Experience of using coronary perfusion balloon catheter for acute middle cerebral artery occlusion,
Surgical Neurology International, Vol.14, No.365, 365, 2023.

(要約): We present the case of an individual with acute occlusion of the middle cerebral artery caused by atherosclerosis. The patient underwent angioplasty using a coronary perfusion balloon, which resulted in a favorable clinical outcome. A 66-year-old male patient presented with an acute onset of right hemiplegia and dysarthria. Magnetic resonance imaging revealed an occlusion of the left middle cerebral artery, and alteplase was administered, followed by a mechanical thrombectomy and intracranial balloon catheter angioplasty. Due to restenosis, a coronary perfusion balloon catheter was used for a 15-minute angioplasty procedure while maintaining the perfusion. This treatment approach led to the recanalization of the artery and favorable clinical outcomes. The coronary perfusion balloon may represent a viable therapeutic alternative for the management of refractory intracranial atherosclerotic large vessel occlusion.

Stent retrieval for free-floating thrombus attached to carotid artery stenosis: A report of two cases.,
Surgical Neurology International, Vol.14, 274, 2023.

(要約): In cases of carotid artery stenosis with FFT, it is technically possible to retrieve a thrombus with a stent retriever. Although thrombus removal may help reduce the risk of ischemic complications in a series of urgent CAS procedures, there are concerns such as mechanical irritation to the carotid artery plaque, and its indications and alternative treatments should be carefully considered.

Cranial geometry in patients with dystonia and Parkinson's disease.,
Scientific Reports, Vol.13, No.1, 2023.

(要約): Abnormal skull shape has been reported in brain disorders. However, no studies have investigated cranial geometry in neurodegenerative disorders. This study aimed to evaluate the cranial geometry of patients with dystonia or Parkinson's disease (PD). Cranial computed tomography images of 36 patients each with idiopathic dystonia (IDYS), PD, and chronic subdural hematoma (CSDH) were analyzed. Those with IDYS had a significantly higher occipital index (OI) than those with CSDH (p = 0.014). When cephalic index (CI) was divided into the normal and abnormal groups, there was a significant difference between those with IDYS and CSDH (p = 0.000, α = 0.017) and between PD and CSDH (p = 0.031, α = 0.033). The age of onset was significantly correlated with the CI of IDYS (τ = - 0.282, p = 0.016). The Burke-Fahn-Marsden Dystonia Rating Scale motor score (BFMDRS-M) showed a significant correlation with OI in IDYS (τ = 0.372, p = 0.002). The cranial geometry of patients with IDYS was significantly different from that of patients with CSDH. There was a significant correlation between age of onset and CI, as well as between BFMDRS-M and OI, suggesting that short heads in the growth phase and skull balance might be related to the genesis of dystonia and its effect on motor symptoms.

Long-sheath Introducer-assisted Revascularization (L-SHARE) Technique for Treating Large-vessel Occlusion by a Giant Clot,
Internal Medicine, Vol.62, No.6, 909-913, 2023.

(要約): Revascularization for common carotid artery (CCA) occlusion might be difficult. We reported our strategy for revascularizing CCA occlusion by giant clots. A 94-year-old woman was transferred to our hospital because of right hemiparesis and aphasia. CCA occlusion and giant clots were detected on ultrasonography. We performed mechanical thrombectomy using a 9-Fr balloon-guiding catheter, stent retriever, and aspiration catheter through a 9-Fr long-sheath introducer [long-sheath introducer-assisted revascularization (L-SHARE) technique]. We successfully recanalized CCA occlusion using this method. The L-SHARE technique might be useful for recanalization of CCA occlusion.

循環器病を防ぐために徳島県循環器病推進計画の中での急性期脳卒中診療の取り組み,
四国医学雑誌, Vol.78, No.5-6, 135-138, 2022年.

(要約): Cerebrovascular and cardiovascular disease are the main causes of death in Japan. The leading causes of the need for long-term care in Japan are also cerebrovascular and cardiovascular disease, which together account for more than one-fourth of the total. The Cerebrovascular and Cardiovascular Disease Control Act, of Japanese national law, was promulgated by a legislative act in 2018. On the basis of the Cerebrovascular and Cardiovascular Disease Control Act, the Ministry of Health, Labour and Welfare, Japan, published the Japanese National Plan for Promotion of Measures Against Cerebrovascular and Cardiovascular Disease (Japanese National Plan) in 2020. By the example of the Japanese National Plan, Tokushima prefecture established a cerebrovascular and cardiovascular disease countermeasure promotion plan to progress cerebrovascular and cardiovascular disease measures according to their own circumstances. One of the important measures of the plan is improving emergency transportation systems. Patients with intracranial large vessel occlusion strokes should be served by direct transfer to endovascular capable centers avoiding delays by misguided transfer to primary stroke centers. Considering the limited availability of endovascular capable centers, accurate identification of patients with high probability of having large vessel occlusion strokes in the prehospital setting is importance. To address this problem, we introduced prehospital scale called Field Assessment Stroke Triage for Emergency Destination (FAST-ED) on emergency transportation systems in Tokushima city.

Diagnosis and Treatment of Tremor in Parkinson's Disease Using Mechanical Devices,
Life, Vol.13, No.1, 78, 2022.

(要約): Parkinsonian tremors are sometimes confused with essential tremors or other conditions. Recently, researchers conducted several studies on tremor evaluation using wearable sensors and devices, which may support accurate diagnosis. Mechanical devices are also commonly used to treat tremors and have been actively researched and developed. Here, we aimed to review recent progress and the efficacy of the devices related to Parkinsonian tremors. The PubMed and Scopus databases were searched for articles. We searched for "Parkinson disease" and "tremor" and "device". Eighty-six articles were selected by our systematic approach. Many studies demonstrated that the diagnosis and evaluation of tremors in patients with PD can be done accurately by machine learning algorithms. Mechanical devices for tremor suppression include deep brain stimulation (DBS), electrical muscle stimulation, and orthosis. In recent years, adaptive DBS and optimization of stimulation parameters have been studied to further improve treatment efficacy. Due to developments using state-of-the-art techniques, effectiveness in diagnosing and evaluating tremor and suppressing it using these devices is satisfactorily high in many studies. However, other than DBS, no devices are in practical use. To acquire high-level evidence, large-scale studies and randomized controlled trials are needed for these devices.

Single-session hematoma removal and transcortical venous approach for coil embolization of an isolated transverse-sigmoid sinus dural arteriovenous fistula in a hybrid operating room: illustrative case,
Journal of Neurosurgery. Case Lessons, Vol.3, No.21, CASE2267, 2022.

(要約): Dural arteriovenous fistula (DAVF) can present with massive hematoma, which sometimes requires emergent removal. Therefore, a surgical strategy for single-session hematoma removal and shunt occlusion in the same surgical field is important. A 73-year-old man was transferred to the authors' hospital with a headache. Brain computed tomography (CT) revealed an intracerebral hematoma in the right temporoparietal lobe (hematoma volume 12 ml). A cerebral angiogram revealed a right isolated transverse-sigmoid sinus (TSS)-DAVF fed by the occipital artery and middle meningeal artery. There was cortical venous reflux into the Labbé vein and posterior parietal vein. Percutaneous transarterial and transvenous embolization were unsuccessful. The following day, his consciousness level acutely declined with a headache, and brain CT showed hematoma expansion (hematoma volume 41 ml) with a midline shift. Therefore, the authors performed single-session hematoma removal and a transcortical venous approach for coil embolization of an isolated TSS-DAVF in a hybrid operating room. His postoperative course was uneventful. No recurrence was observed 3 months postoperatively on cerebral angiography. Single-session hematoma removal and a transcortical venous approach for coil embolization of an isolated TSS-DAVF is considered in cases with massive hematoma. This strategy is useful, considering recent developments in hybrid operating rooms.

Seizure types associated with negative arterial spin labeling and positive diffusion-weighted imaging on peri-ictal magnetic resonance imaging,
Journal of the Neurological Sciences, Vol.436, 1-8, 2022.

(要約): Arterial spin labeling (ASL) and diffusion-weighted imaging (DWI) are useful for assessing hyperperfusion and cytotoxic edema, respectively, caused by acute seizures. This study investigated the clinical characteristics associated with normal ASL findings and DWI abnormalities in patients with acute seizures. Overall, 41 patients with ASL and DWI images that were obtained within 48 h of focal onset seizure diagnosis, due to epilepsy or acute symptomatic seizures, were divided into groups based on initial ASL findings (ASL-negative vs. ASL-positive), and DWI abnormalities (DWI-negative vs. DWI-positive). The diagnosis was made based on seizure semiology, electroencephalography, and conventional imaging modalities. ASL and DWI abnormalities were based on visual assessment. Of the 41 patients, eight (19.5%) displayed normal ASL findings. The proportion of patients with focal aware seizures (FAS) was significantly higher among ASL-negative patients (62.5%) than that in ASL-positive patients (15.2%); the proportion of patients with focal impaired awareness seizures (FIAS) was significantly lower among ASL-negative patients (12.5%) than that among ASL-positive patients (57.6%). Hyperintensity findings on DWI were observed in 12 patients (29.3%, DWI-positive). The proportion of patients with FIAS was significantly higher among DWI-positive patients (75.0%) than that among DWI-negative patients (37.9%). Multivariate analysis revealed that FAS and FIAS were associated with normal ASL findings (odds ratio [OR]: 21.37, P = 0.010) and DWI abnormalities (OR = 6.11, P = 0.028). A diagnosis of seizures should not be excluded based on normal ASL findings, especially in patients with FAS. FIAS may be a risk factor for neuronal damage caused by seizure activity.

The claw sign predicts first-pass effect in mechanical thrombectomy for cerebral large vessel occlusion in the anterior circulation,
Surgical Neurology International, Vol.13, No.72, 1-7, 2022.

(要約): Mechanical thrombectomy (MT) is an effective treatment for acute cerebral large vessel occlusion (LVO). Complete recanalization of vessels in a single procedure is defined as the first-pass effect (FPE) and is associated with good prognosis. In this study, angiographic clot protruding sign termed the "claw sign," was examined as candidate preoperative imaging factor for predicting the FPE. We retrospectively analyzed data from 91 consecutive patients treated for acute LVO in the anterior circulation by MT between January 2014 and December 2019. The claw sign was defined as a thrombus that protruded proximally by more than half of the diameter of the parent artery. Radiological findings such as claw sign, clinical and etiological features, and outcomes were compared between groups with and without successful FPE. Multivariate analysis was conducted to evaluate perioperative factors associated with FPE. FPE was achieved in 26 of 91 (28.6%) patients and the claw sign was observed in 34 of 91 (37.4%) patients. The claw sign was significantly more frequent in the successful FPE group than in the failed FPE group (53.8% vs. 30.8%; = 0.040). After the multivariate analysis, the claw sign was the only pretreatment parameter that could predict FPE (odds ratio, 2.67; 95% confidence interval, 1.01-7.06; = 0.047). The claw sign is an angiographic imaging factor that might predict FPE after MT for anterior circulation acute ischemic stroke.

Subarachnoid Hemorrhage Due to Rupture of Vertebral Artery Dissecting Aneurysms: Treatments, Outcomes, and Prognostic Factors,
World Neurosurgery, Vol.152, e86-e93, 2021.

(要約): Mortality rate after subarachnoid hemorrhage due to rupture of vertebral artery dissecting aneurysms (VADAs) is high; endovascular coil trapping is the first-line therapy to prevent rerupture. To select optimal treatments, the positional relationship between the VADA and posterior inferior cerebellar artery (PICA) and the morphology of the contralateral vertebral artery must be considered, and outcome predictors of different treatment methods and their possible complications must be identified. We retrospectively studied 44 patients with ruptured VADAs who had undergone endovascular or surgical treatment. VADA morphology was assessed on conventional preoperative angiograms, and VADAs were categorized based on their site in relation to the PICA. VADA site, treatment method, and complications were used to identify prognostic factors. The sites of the 44 VADAs were PICA-proximal (n = 3), PICA-distal (n = 22), PICA-absent (n = 7), and PICA-involved (n = 12). Treatments included internal coil trapping (n = 30), proximal coil occlusion (n = 5), and stent placement (n = 3); surgical flow alteration via an occipital artery-PICA bypass and ligation at the proximal vertebral artery and the PICA origin was performed in 6 patients. Periprocedural rebleeding was associated with a poor outcome. Internal coil trapping prevented the rerupture of PICA-proximal and PICA-absent VADAs, and flow alteration prevented rerupture of PICA-involved VADAs; there were no complications directly attributable to these procedures. Periprocedural rebleeding was a poor prognostic factor. Internal trapping of PICA-proximal and PICA-absent VADAs and flow alteration in PICA-involved VADAs prevented rerupture.

Coil embolization with overlapping horizontal low-profile stents to treat a giant thrombosed fetal posterior cerebral aneurysm using contralateral approach through anterior communicating artery: Case report.,
Surgical Neurology International, Vol.12, No.347, 2021.

(要約): The treatment of internal carotid artery (ICA) - posterior communicating artery aneurysms (ICPC aneurysms) is challenging when a fetal posterior cerebral artery (PCA) arises from the saccular neck. This complex angioarchitecture renders endovascular approaches difficult. Giant thrombosed IC-PC aneurysms are also hard to treat by endovascular coiling because its flow-diversion effect is insufficient. We report the first case of a ruptured giant thrombosed IC-PC aneurysm associated with a fetal PCA that was successfully treated by coil embolization with retrograde overlap horizontal stenting using low-profile stents introduced through the contralateral ICA. The aneurysm was completely occluded and follow-up MRI scans demonstrated the reduction of the aneurysmal size. Our technique is advantageous because low-profile stents can be used to treat lesions not accessible with flow-diverter stents due their presence in complex angioarchitectures, and overlap stenting may have flow-diversion effects that can result in the complete occlusion of giant thrombosed aneurysms.

(要約): Objective: During percutaneous transluminal angioplasty (PTA) for the vertebral artery, occlusion of the subclavian artery using a balloon guiding catheter may be useful to prevent embolism of clots and/or debris distal to an atherosclerotic lesion. However, when placing a balloon guiding catheter at the intended vessels is difficult, it may be useful to use an aspiration catheter (AC) for mechanical thrombectomy as an intermediate catheter to suction way clots and/or debris. We report two cases in which PTA was performed for an atherosclerotic lesion at the intracranial vertebral artery using an AC, which ended without complications.Case Presentations: Case 1: A 74-year-old man presented with dysarthria and was admitted to our hospital. MRI revealed severe left vertebral artery stenosis and diffuse cerebral infarct areas at the territory of the posterior circulation. The patient had an abdominal aortic aneurysm and abnormally shaped left tortuous subclavian artery. Therefore, we performed PTA and stenting via the left brachial artery. We guided a 6-Fr long sheath to the left subclavian artery, and a 6-Fr AC for thrombectomy was guided through the long sheath to the V4 portion of the left vertebral artery. Thereafter, PTA was carried out under manual aspiration from the AC. As restenosis at the atherosclerotic lesion occurred after PTA, we performed stenting using a coronary stent system for this lesion under manual aspiration from the AC. No new infarct areas were observed on post-procedural MRI. Case 2: A 74-year-old woman presented with dysarthria and was admitted to our hospital. MRI demonstrated basilar artery occlusion and diffuse cerebral infarct areas at the territory of the posterior circulation. As her symptom worsened after admission, we performed urgent mechanical thrombectomy. We first performed thrombectomy using a stent retriever and then performed PTA and stenting (PTAS) for residual basilar artery stenosis via the AC under manual aspiration.Conclusion: When it is difficult to place a guiding catheter at the intended vessels during PTA, an AC may be useful to prevent distal embolization.

Elevated Urinary Titin and its Associated Clinical Outcomes after Acute Stroke.,
Journal of Stroke & Cerebrovascular Diseases, Vol.30, No.3, 2021.

(要約): Forty-one patients were included (29 male; age, 68 ± 15 years), 29 had ischemic stroke, 8 had intracerebral hemorrhage, and 4 had subarachnoid hemorrhage. The levels of urinary titin on days 1, 3, 5, and 7 were 9.9 (4.7-21.1), 16.2 (8.6-22.0), 8.9 (4.8-15.2), and 8.7 (3.6-16.2) pmol/mg Cr, respectively. The peak urinary titin level was associated with the mRS score (r = 0.55, p < 0.01), the NIHSS score (r = 0.72, p < 0.01), and the BI (r = -0.59, p < 0.01) upon hospital discharge. In multivariate analysis, the peak urinary titin was associated with poor outcome (p = 0.03).

Ataxia with vitamin E deficiency in the Philippines: A case report of two siblings.,
The Journal of Medical Investigation : JMI, Vol.68, No.3.4, 400-403, 2021.

(要約): Here we report two siblings with ataxia and peripheral neuropathy. One patient showed head tremors. Genetic analysis revealed a mutation in the hepatic α-tocopherol transfer protein (α-TTP) gene (TTPA) on chromosome 8q13. They were diagnosed with ataxia with vitamin E deficiency which is firstly reported in the Philippines. As the symptoms of ataxia with vitamin E deficiency can be alleviated with lifelong vitamin E administration, differential diagnosis from similar syndromes is important. In addition, ataxia with vitamin E deficiency causes movement disorders. Therefore, a common hereditary disease in the Philippines, X-linked dystonia-parkinsonism, could be another differential diagnosis. The Philippines is an archipelago comprising 7,107 islands, and the prevalence of rare hereditary diseases among the populations of small islands is still unclear. For neurologists, establishing a system of genetic diagnosis and counseling in rural areas remains challenging. These unresolved problems should be addressed in the near future. J. Med. Invest. 68 : 400-403, August, 2021.

Factors associated with DWI-ASPECTS score in patients with acute ischemic stroke due to cerebral large vessel occlusion,
Clinical Neurology and Neurosurgery, Vol.199, 106316, 2020.

(要約): The Alberta Stroke Program Early CT score (ASPECTS) of patients with acute ischemic stroke at the time of admission varies. It is crucial to select appropriate methods of treatment, such as recombinant tissue-plasminogen activator, and/or endovascular thrombectomy. According to the recent guidelines, endovascular thrombectomy for patients with large vessel occlusion (LVO) and lesion of ischemic tissue that was not yet infarcted is effective. This result demonstrates the importance of patient selection based on neuroradiological imaging. However, there are many patients who are judged as ineligibility for recanalization therapy because of presence of large ischemic core, indicating unfavorable ASPECTS, at the time of admission. We investigated the factors associated with favorable diffusion-weighted image (DWI)-ASPECTS score at the time of admission. We studies patients with LVO within 24 h from onset who were admitted into our hospital. We divided them into two groups, with favorable DWI-ASPECTS (≥6), and unfavorable DWI-ASPECTS (<6) at the time of admission. We investigated factors associated with favorable DWI-ASPECTS by evaluation of our patients' severity of clinical symptom, etiology, and radiological findings. This study showed that mild white matter lesion (Fazekas scale ≤1), absence of internal carotid artery (ICA) occlusion and cardioembolic stroke were independent factor of favorable DWI-ASPECTS at the time of admission. (odds ratio 12.92, p < 0.001, odds ratio 0.31, p = 0.001, odds ratio 0.16, p = 0.001, respectively) CONCLUSIONS: Absence of severe white matter lesion, cardioembolic stroke, and ICA occlusion might be associated with favorable DWI-ASPECTS at the time of admission.

Can Pallidal Deep Brain Stimulation Rescue Borderline Dystonia? Possible Coexistence of Functional (Psychogenic) and Organic Components.,
Brain Sciences, Vol.10, No.9, 636, 2020.

(要約): The diagnosis and treatment of functional movement disorders are challenging for clinicians who manage patients with movement disorders. The borderline between functional and organic dystonia is often ambiguous. Patients with functional dystonia are poor responders to pallidal deep brain stimulation (DBS) and are not good candidates for DBS surgery. Thus, if patients with medically refractory dystonia have functional features, they are usually left untreated with DBS surgery. In order to investigate the outcome of functional dystonia in response to pallidal DBS surgery, we retrospectively included five patients with this condition. Their dystonia was diagnosed as organic by dystonia specialists and also as functional according to the Fahn and Williams criteria or the Gupta and Lang Proposed Revisions. Microelectrode recordings in the globus pallidus internus of all patients showed a cell-firing pattern of bursting with interburst intervals, which is considered typical of organic dystonia. Although their clinical course after DBS surgery was incongruent to organic dystonia, the outcome was good. Our results question the possibility to clearly differentiate functional dystonia from organic dystonia. We hypothesized that functional dystonia can coexist with organic dystonia, and that medically intractable dystonia with combined functional and organic features can be successfully treated by DBS surgery.

Cone beam-computed tomography angiography by intravenous contrast injection is reliable to evaluate patients with large vessel occlusion,
Journal of Clinical Neuroscience, Vol.70, 67-71, 2019.

(要約): Mechanical thrombectomy (MT) for acute ischemic stroke (AIS) patients due to emergent large vessel occlusion (ELVO) is standard treatment, the benefits, however, are highly time-sensitive. After patient eligibility for reperfusion therapy is determined by conventional radiological examinations, the time to be transferred from the department of radiological examination to angiography-suites is critical. We speculated that the time required for the diagnosis of AIS might be reduced if we could determine MT eligibility in patients with ELVO at angiography-suites. Modern angiography-suites with flat panel detectors can perform cone beam (CB)-CT. We performed CB-CTA using intravenous injection of contrast agent to evaluate occlusion sites, collateral score, and construction of vessels distal to occlusion sites and determined if CB-CTA could be useful to evaluate patients with ELVO. We included 15 patients with ELVO diagnosed by conventional MRI or CT/CTA, and investigated whether CB-CTA was reliable to diagnose occlusion sites. We also studied if collateral score on CB-CTA was associated with prognosis after successful reperfusion by MT by comparison between favorable (modified Rankin scale (mRS) 0-2), and unfavorable outcome group (mRS 3-6). There was strong agreement of occlusion sites between CB-CTA and conventional radiological examination (κ = 0.80). Collateral score determined by CB-CTA was significantly different between favorable outcome and unfavorable outcome group (median collateral score 2.3 v.s. 1.3, p = 0.040). Although prospective study of AIS patients at a radiography department is indispensable, CB-CTA performed in an angiography-suite might be useful to evaluate patients with ELVO.

Active Cancer and Elevated D-Dimer Are Risk Factors for In-Hospital Ischemic Stroke,
Cerebrovascular Diseases Extra, Vol.9, No.3, 129-138, 2019.

(要約): Little attention has been paid to the pathogenesis of in-hospital stroke, despite poor outcomes and a longer time from stroke onset to treatment. We studied the pathophysiology and biomarkers for detecting patients who progress to in-hospital ischemic stroke (IHS). Seventy-nine patients with IHS were sequentially recruited in the period 2011-2017. Their characteristics, care, and outcomes were compared with 933 patients who had an out-of-hospital ischemic stroke (OHS) using a prospectively collected database of the Tokushima University Stroke Registry. Active cancer and coronary artery disease were more prevalent in patients with IHS than in those with OHS (53.2 and 27.8% vs. 2.0 and 10.9%, respectively; p < 0.001), the median onset-to-evaluation time was longer (300 vs. 240 min; p = 0.015), and the undetermined etiology was significantly higher (36.7 vs. 2.4%; p < 0.001). Although there was no significant difference in stroke severity at onset between the groups, patients with IHS had higher modified Rankin Scale (mRS) scores (3-6) at discharge (67.1 vs. 50.3%; p = 0.004) and rates of death during hospitalization (16.5 vs. 2.9%; p < 0.001). D-dimer (5.8 vs. 0.8 µg/mL; p < 0.001) and fibrinogen (532 vs. 430 mg/dL; p = 0.014) plasma levels at the time of onset were significantly higher in patients with IHS after propensity score matching. Multivariate logistic regression analysis revealed that active cancer (odds ratio [OR] 2.30; 95% confidence interval [CI] 1.26-4.20), prestroke mRS scores 3-5 (OR 6.78; 95% CI 3.96-11.61), female sex (OR 1.57; 95% CI 1.19-2.08), and age ≥75 years (OR 2.36; 95% CI 1.80-3.08) were associated with poor outcomes. Patients with IHS had poorer outcomes than those with OHS because of a higher prevalence of active cancer and functional dependence before stroke onset. Elevated plasma levels of D-dimer and fibrinogen, especially with active cancer, can help identify patients who are at a higher risk of progression to IHS.

The Claw Sign: An angiographic Predictor of Recanalization After Mechanical Thrombectomy for Cerebral Large Vessel Occlusion.,
Journal of Stroke & Cerebrovascular Diseases, Vol.28, No.6, 1555-1560, 2019.

(要約): Mechanical thrombectomy undoubtedly improves functional outcomes for patients with acute ischemic stroke. Although we have observed occlusion sites that protrude proximally into the vessel on angiography, termed the "claw sign," we have been unable to state its clinical significance. In this study, we aimed to determine whether the presence of a claw sign was related to recanalization success after mechanical thrombectomy. We retrospectively included 73 consecutive patients treated for acute cerebral large vessel occlusion by mechanical thrombectomy between January 2014 and December 2017. The angiographic claw sign was defined as a thrombus that protruded proximally by more than half the diameter of the parent artery. Claw sign positivity, clinical and etiological features, and outcomes were compared between groups with and without recanalization. The claw sign was observed in 29 of 73 (40%) patients and was positive significantly more frequently in those with recanalization (50.0%) than in those without recanalization (5.9%) (P < .01). By multivariate analysis, the claw sign was the only pretreatment parameter to predict successful recanalization (odds ratio, 12.50; 95% confidence interval, 1.50-103.00; P = .019). The presence of the claw sign might predict successful recanalization in patients undergoing mechanical thrombectomy for large vessel occlusion.

Dural arteriovenous fistula in the superior orbital fissure,
Surgical Neurology International, Vol.9, No.1, 95, 2018.

(要約): Dural arteriovenous fistulas (dAVFs) are extremely rare in the superior orbital fissure, and they exhibit ocular symptoms similar to the dAVF in the cavernous sinus because of the intraorbital venous congestion. Hence, the distinction of these conditions is imperative because of some inherent differences in endovascular treatment techniques. A 58-year-old woman presented with a gradually worsening left eyeball protrusion and conjunctival congestion. The digital subtraction angiography revealed a dAVF with a shunting point in the left superior orbital fissure. Moreover, the inferolateral trunk of the left internal carotid artery and the left middle meningeal artery were involved as feeding arteries. Shunting blood flow drained into the facial vein through the superior ophthalmic vein (SOV) but not into the cavernous sinus, which was located just posterior to the superior orbital fissure. We performed transvenous coil embolization in the SOV through the facial vein, and the symptoms disappeared completely. We experienced a case of a dAVF in the superior orbital fissure. This case presented a possibility of the presence of one subtype of the dAVF in the part of the cavernous sinus separated at the superior orbital fissure in front. Transvenous coil embolization in the SOV through the facial vein efficiently occluded the fistula.

Risk Factors of Neurological Deterioration in Patients with Cerebral Infarction due to Large Artery Atherosclerosis,
Journal of Stroke & Cerebrovascular Diseases, Vol.26, No.8, 1801-1806, 2017.

(要約): In some patients with acute ischemic stroke, neurological deterioration (ND) is observed, and it is difficult to predict at the time of admission. Especially in some patients with large-artery atherosclerosis (LAA), aggressive medical treatments and surgical interventions might be helpful to prevent ND. Therefore, we investigated factors associated with ND in patients with LAA. We studied patients with LAA who were admitted to our hospital. We divided them into 2 groups with (group 1) and without deterioration (group 2), and evaluated their medical records, risk factors, and radiological findings, such as number of diffusion-positive lesion and degree of stenosis. Our study population consisted of 171 patients; 71 (41.5%) did and 100 (58.5%) did not suffer deterioration. By univariate analysis, blood pressure (BP), heart rate, National Institutes of Health Stroke Scale (NIHSS) score, number of diffusion-positive lesion, count of red blood cell, high-density lipoprotein, and degree of stenosis differed significantly between the 2 groups. By multivariate analysis, systolic BP (170 mm Hg, odds ratio: 7.20, P <.001) was associated with ND. Furthermore, number of diffusion-weighted image (DWI)-positive lesion (8), degree of stenosis (>80.0%), and NIHSS score (4) were also independent factors associated with ND. High BP, severity of neurological deficit at the time of admission, and radiological findings, such as degree of stenosis and number of DWI-positive lesion, are independently associated with ND in patients with LAA.

Treatment Outcome of Carotid Artery Stenting Underwent within 14 Days of Stroke Onset - Consideration of Safety and Efficacy of Urgent Carotid Artery Stenting for Neurologically Progressing Patients,
Neurologia Medico-Chirurgica, Vol.57, No.6, 278-283, 2017.

(要約): As the safety and effectiveness of urgent carotid artery stenting (CAS) for neurologically progressing patients remain controversial, we retrospectively analyzed the outcome of urgent CAS based on the patients' pathophysiological condition and neuroimaging findings. We divided 71 patients who underwent CAS within 14 days of stroke onset into two groups. Group 1 (n = 35) was comprised of patients with progressing neurologic signs and a reversible ischemic penumbra on magnetic resonance images (MRI). They were treated by urgent CAS. Group 2 (n = 36) was neurologically stable and underwent prophylactic CAS. In all patients we recorded the National Institutes of Health Stroke Scale (NIHSS) score and the modified Rankin scale (mRS). Urgent CAS resulted in significant improvement in the NIHSS score, when compared before and after CAS in group 1 (5.3 ± 4.3, P < 0.01). The rate of good outcomes (mRS 0-2 at 3 months post-CAS) was 48.6% in group 1, and 75% in group 2. The cumulative incidence of ipsilateral stroke between 31 days and 1 year was 5.9% in group 1, and 0% in group 2. The procedural complication rate was similar in both groups (group 1: 5.7%, n = 2; group 2: 5.6%, n = 2). No patient suffered a symptomatic intracerebral hemorrhage. When the pathophysiological status and neuroimaging findings are used to determine patient eligibility for urgent CAS, this treatment improve neurologic outcome and can be performed as safely as prophylactic CAS in our cohort of patients with acute ischemic stroke.

Intra-arterial high signals on arterial spin labeling perfusion images predict the occluded internal carotid artery segment,
Neuroradiology, Vol.59, No.6, 587-595, 2017.

(要約): Arterial spin labeling (ASL) involves perfusion imaging using the inverted magnetization of arterial water. If the arterial arrival times are longer than the post-labeling delay, labeled spins are visible on ASL images as bright, high intra-arterial signals (IASs); such signals were found within occluded vessels of patients with acute ischemic stroke. The identification of the occluded segment in the internal carotid artery (ICA) is crucial for endovascular treatment. We tested our hypothesis that high IASs on ASL images can predict the occluded segment. Our study included 13 patients with acute ICA occlusion who had undergone angiographic and ASL studies within 48 h of onset. We retrospectively identified the high IAS on ASL images and angiograms and recorded the occluded segment and the number of high IAS-positive slices on ASL images. The ICA segments were classified as cervical (C1), petrous (C2), cavernous (C3), and supraclinoid (C4). Of seven patients with intracranial ICA occlusion, five demonstrated high IASs at C1-C2, suggesting that high IASs could identify stagnant flow proximal to the occluded segment. Among six patients with extracranial ICA occlusion, five presented with high IASs at C3-C4, suggesting that signals could identify the collateral flow via the ophthalmic artery. None had high IASs at C1-C2. The mean number of high IAS-positive slices was significantly higher in patients with intra- than extracranial ICA occlusion. High IASs on ASL images can identify slow stagnant and collateral flow through the ophthalmic artery in patients with acute ICA occlusion and help to predict the occlusion site.

Usefulness of 3-Tesla magnetic resonance arterial spin-labeled imaging for diagnosis of cranial dural arteriovenous fistula,
Journal of the Neurological Sciences, Vol.372, 428-432, 2017.

(要約): Conventional digital subtraction angiography (DSA) has been a useful tool for the diagnosis of cranial dural arteriovenous fistula (cDAVF). In most patients with cDAVF, blood flow through the arteriovenous shunt was pooled at diseased veins and/or sinuses. Therefore, we speculated that pooled blood at diseased veins in patients with cDAVF could be detected on arterial spin-labeled imaging (ASL). The purpose of the present study was to investigate the usefulness of ASL to detect cDAVF. Consecutive 13 patients with cDAVF who were admitted to our hospital between April 2013 and September 2016 were included in our study. We performed magnetic resonance imaging (MRI), including ASL, before DSA and within 7days after treatment for all of our patients. The accuracy for diagnosis of cDAVF was compared between conventional MRI findings and ASL findings. We also investigated the difference in ASL findings before and after treatment. We could detect venous ASL signals in 12 patients, and this was more sensitive for diagnosis of cDAVF versus conventional MRI findings. ASL found the same location of cDAVF as conventional angiography. After successful treatment, venous ASL signals disappeared. ASL might be useful to detect cDAVF and predict the location of diseased sinuses.

Optimal Timing of Diffusion-Weighted Imaging to Avoid False-Negative Findings in Patients With Transient Ischemic Attack,
Stroke, Vol.48, No.7, 1990-1992, 2017.

(要約): We aimed to investigate the optimal timing of diffusion-weighted imaging (DWI) in patients with transient ischemic attack (TIA). Seventy-three consecutive patients with TIA underwent DWI on admission (initial DWI) and at 24 hours after admission (second DWI). Patients were divided into 2 groups based on initial DWI findings in relation to the second examination: false negative (group 1) and other (group 2). The probability of initial false-negative findings was determined for each hour from TIA onset to initial DWI. Multivariate analysis was used to evaluate the independent risk factors associated with false-negative findings on initial DWI. Of the 73 patients examined (56 men; mean age, 68 years), 9 (12%) were categorized into group 1. The latency from TIA onset to initial DWI was 1.7±0.6 hours for group 1 (range, 1-2.8 hours) and 3.3±2.6 hours for group 2 (range, 35 minutes to 12 hours). The probability of false-negative findings on initial DWI decreased in a time-dependent manner (25%, 21%, and 7% for 1, 2, and 3 hours, respectively), and no false-negative findings were observed on initial DWI performed at >3 hours from symptom onset. Short latency (2 hours) from TIA onset to initial DWI was an independent risk factor related to false-negative findings (odds ratio, 13.11; 95% confidence interval, 1.07-161.38; P=0.045). If the duration between TIA symptom onset and initial DWI is <2 hours, a repeat examination should be performed to minimize the risk of false-positive findings.

Coexistence of Quasi-moyamoya Disease and POEMS Syndrome in a Patient with Intracranial Hemorrhage: A Case Report and Literature Review,
NMC Case Report Journal, Vol.4, 5-9, 2017.

(要約): POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome is a rare paraneoplastic syndrome elicited by plasma cell dyscrasia. Its clinical manifestations are multiple and stroke is not a recognized feature. A 44-year-old woman with a 3-month history of bilateral lower extremity sensorimotor disturbance was admitted to our hospital. Examinations revealed polyneuropathy, organomegaly, hypothyroidism, monoclonal gammopathy, pelvic plasmacytoma, and elevated serum vascular endothelial growth factor (VEGF) levels. A diagnosis of POEMS was made. Her condition was improved by radiation therapy of her pelvic plasmacytoma and she continued to be seen on an outpatient basis. Five years after her first admission she was re-admitted with sudden-onset right hemiparesis. A brain computed tomography (CT) scan revealed a left intracranial hemorrhage and magnetic resonance (MR) angiography and cerebral angiography showed occlusion of the proximal portion of the bilateral middle cerebral artery and narrowing of the bilateral internal carotid artery at the terminal portion; moyamoya vessels were seen. This is the first report of a patient whose intracranial hemorrhage was attributable to quasi-moyamoya disease associated with POEMS syndrome. We suggest that the POEMS syndrome be ruled out in the differential diagnosis of patients presenting with atypical stroke, multivessel stenotic lesions (moyamoya vessels), and polyneuropathy.

徳島大学病院脳卒中センターに搬送されたrt-PA静注療法の"Drip and Ship"症例における検討,
四国医学雑誌, Vol.72, No.3-4, 107-112, 2016年.

(要約): Recently,"Drip and Ship"treatment conducted in collaboration of a hospital in remote area and an institution capable of emergency stroke treatment under guidance by a stroke specialist has been reported to be effective. "Drip and Ship" treatment refers to initiating intravenous recombinant tissue-type plasminogen activator(rt-PA)infusion at a remote hospital(Drip)and then transporting patients to an institution capable of multimodality management and endovascular treatment of stroke(Ship). We report here a case analysis and examinations on treatment methods, prognosis, and some other parameters in 16 patients who were transported to the Stroke Care Unit(SCU)of the Tokushima University Hospital while undergoing"Drip and Ship"treatment between June 2013 and November 2015. Occluded vessels were recanalized by rt-PA administration in 5/12patients (42%). For 6 cases in which recanalization was not achieved with rt-PA, endovascular treatment was performed, and recanalization was obtained in 3 patients(50%). There was a marked improvement(8 4points on average)in NIHSS at the time of discharge compared to that before rt-PA administration. A representative case showed a 26-point improvement in NIHSS at the time of discharge compared to the pretreatment value. The advantage of"Drip and Ship"treatment is two-fold : It allows for rt-PA treatment of acute ischemic stroke patients at remote-area institutions incapable of multimodality stroke management, and also makes it possible to add endovascular treatment for rt-PA-irresponsive cases in which recanalization of occluded vessels could not be achieved with rt-PA therapy. The results suggest that the"Drip and Ship"treatment is a safe and effective means to eliminate regional disparities in intravenous rt-PA therapy and can make more contributions to the collaborative stroke care in the Tokushima prefecture in the future.

The susceptibility vessel sign containing two compositions on 3-tesla T2*-weighted image and single corticosubcortical infarct on diffusion-weighted image are associated with cardioembolic stroke,
Journal of the Neurological Sciences, Vol.359, No.1-2, 141-145, 2015.

(要約): Although accurate diagnosis of the ischemic stroke subtype is one of the most important factors for selection of therapeutic approach, it is sometimes difficult at the time of admission. We previously reported that susceptibility vessel sign (SVS) with two layers (termed two-layered SVS) on 3-tesla-T2*-weighted image (T2*-WI) might be useful to predict cardioembolic stroke in patients with cerebral major vessel occlusion. We studied about biomarkers on magnetic resonance imaging (MRI), including two-layered SVS for diagnosing cardioembolic stroke. We included 132 ischemic stroke patients within 24h from onset who suffered internal carotid artery or middle cerebral artery occlusion due to cardioembolic stroke (group CE) or large artery atherosclerosis (group LAA). We studied about biomarkers on MRI such as two-layered SVS and abnormal finding patterns of diffusion-weighted image (DWI) for diagnosis of cardioembolic stroke in addition to laboratory data, physiological examination, and clinical findings. In this study, 132 patients (72 men and 60 women, age 74.5 ± 12.1 years) were included. Of these, 63 (47.7%) were cardioembolic stroke. In univariate analysis, frequency of comorbid atrial fibrillation, presence of two-layered SVS on T2*-WI and that of single corticosubcortical infarct on DWI, intima-media thickness were significantly higher in group CE. In multivariate analysis, the presence of two-layered SVS and single corticosubcortical infarct were associated with cardioembolic stroke (odds ratio, two-layered SVS, 30.08, p<0.001; single corticosubcortical infarct, 15.78, p<0.001). Biomarkers associated with cardioembolic stroke may be two-layered SVS on T2*-WI and single corticosubcortical infarct on DWI.

Predictors of a favorable outcome after recanalization in patients with cerebral major vessel occlusion,
Journal of Stroke & Cerebrovascular Diseases, Vol.24, No.12, 2793-2799, 2015.

(要約): Although tissue plasminogen activator and endovascular treatment were reported to be useful for recanalization in patients with major vessel occlusion (MVO), the outcome in some patients with recanalization was unfavorable. We could detect prolongation of the ipsilateral posterior cerebral artery (PCA) to the ischemic side on magnetic resonance angiography in some patients (ipsilateral-PCA sign). We investigated the predictors including radiological findings for a favorable outcome after successful recanalization. We included 76 patients with MVO of the anterior circulation and documented recanalization by treatment. We divided our patients into 2 groups: group F (modified Rankin scale [mRS] score = 0-2) and group UF (mRS score = 3-6). We compared biomarkers between the groups. National Institutes of Health Stroke Scale (NIHSS) score before treatment in group F (8.5) was lower than that in group UF (16.0; P <.001). Sensitivity of the ipsilateral-PCA sign was commonly associated with group F (67.5% versus 19.4%, P <.001), and specificity of the sign was 80.6%. Absence of infarcts in the anterior cerebral artery (ACA) territory and ACA occlusion were also associated with a favorable outcome. In multivariate analysis, the ipsilateral-PCA sign and NIHSS score (≤ 10) were independent predictors of favorable outcome (odds ratio = 9.92, 95% confidence interval [CI] 2.71-36.23, P = .001; and odds ratio = 9.15, 95% CI 2.44-34.36, P = .001, respectively) The ipsilateral-PCA sign and low NIHSS score (≤ 10) were predictors of a favorable outcome in patients with MVO and documented recanalization by treatments.

Is the Susceptibility Vessel Sign on 3-Tesla Magnetic Resonance T2*-Weighted Imaging a Useful Tool to Predict Recanalization in Intravenous Tissue Plasminogen Activator?,
Clinical Neuroradiology, 2014.

(要約): The aim of this study was to investigate the independent factors associated with the absence of recanalization approximately 24 h after intravenous administration of tissue-type plasminogen activator (IV TPA). The previous studies have been conducted using 1.5-Tesla (T) magnetic resonance imaging (MRI). We studied whether the characteristics of 3-T MRI findings were useful to predict outcome and recanalization after IV tPA. Patients with internal carotid artery (ICA) or middle cerebral artery (MCA) (horizontal portion, M1; Sylvian portion, M2) occlusion and treated by IV tPA were enrolled. We studied whether the presence of susceptibility vessel sign (SVS) at M1 and low clot burden score on T2*-weighted imaging (T2*-CBS) on 3-T MRI were associated with the absence of recanalization. A total of 49 patients were enrolled (27 men; mean age, 73.9 years). MR angiography obtained approximately 24 h after IV tPA revealed recanalization in 21 (42.9 %) patients. Independent factors associated with the absence of recanalization included ICA or proximal M1 occlusion (odds ratio, 69.6; 95 % confidence interval, 5.05-958.8, p = 0.002). In this study, an independent factor associated with the absence of recanalization may be proximal occlusion of the cerebral arteries rather than SVS in the MCA or low T2*-CBS on 3-T MRI.

The two-1 layered susceptibility vessel sign on 3-tesla T2*-weighted imaging is a predictive biomarker of stroke subtype,
Stroke, Vol.46, No.1, 269-271, 2014.

(要約): A susceptibility vessel sign (SVS) on 1.5-tesla (T)-T2*-weighted images may predict cardioembolism. It has also been detected in patients with large artery atherosclerosis. In patients with major vessel occlusion, the SVS was comprised 2 layers on 3T-T2*-weighted images. We assessed the efficacy of 2-layered SVS on 3T-T2*-weighted imaging scans for predicting cardioembolism. Our study included 132 patients who had ischemic stroke within the preceding 24 hours and presented with internal carotid artery or middle cerebral artery occlusion because of cardioembolism or large artery atherosclerosis. We compared 2-layered SVS and SVS on 3T-T2*-weighted imaging scans for their sensitivity, specificity, and diagnostic odds ratio for predicting cardioembolism. We enrolled 132 patients (72 men; mean age, 74.5 years); of these, 63 (47.7%) were presented with cardioembolism. Although the sensitivity of SVS and 2-layered SVS for cardioembolism and large artery atherosclerosis was not statistically different (74.6% and 58.0%, respectively), the sensitivity of 2-layered SVS was significantly higher in patients with cardioembolism (42.9%) than those with large artery atherosclerosis (2.9%; P<0.001). The specificity and diagnostic odds ratio for 2-layered SVS for cardioembolism were 97.1% and 25.1; for SVS they were 42.0% and 2.1, respectively. The specificity of 2-layered SVS for cardioembolism was high. It may be useful for predicting cardioembolism and for the management of patients with acute ischemic stroke.

Predictors of neurologic deterioration in patients with small-vessel occlusion and infarcts in the territory of perforating arteries,
Journal of Stroke & Cerebrovascular Diseases, Vol.23, No.8, 2151-2155, 2014.

(要約): It is difficult to predict neurologic deterioration in patients with small-vessel occlusion (SVO), that is, small infarcts in the territory of cerebral perforating arteries. We reviewed 110 patients with SVO who were admitted to our hospital. We divided them into groups with (n = 32, group 1) and without deterioration (n = 78, group 2) and evaluated their medical records, risk factors, magnetic resonance imaging findings, grade of periventricular hyperintensity (PVH), maximum diameter of the infarct area, and the number of slices showing infarcts on diffusion-weighted images (DWI). Our study population consisted of 110 patients (71 males and 39 females; mean age 69.2 years): 32 (29%) did and 78 (71%) did not suffer deterioration. By univariate analysis, the age, current smoking, history of stroke, maximum diameter of the infarcted area, number of DWI slices with infarcts, frequency of PVH, and PVH grade based on Fazekas classification differed significantly between the 2 groups. By multivariate analysis, conventional risk factors other than PVH and history of stroke were not associated with neurologic deterioration (PVH grade ≥ 2 versus PVH grade ≤ 1, odds ratio 6.72, P = .006; with stroke versus without stroke, odds ratio .21, P = .049). We also found that higher the PVH grade, the worse the National Institutes of Health Stroke Scale score at the time of discharge. PVH and without history of stroke are independently associated with neurologic deterioration in patients with SVO.

Intra-arterial signal on arterial spin labeling perfusion MRI to identify the presence of acute middle cerebral artery occlusion,
Cerebrovascular Diseases, Vol.38, No.3, 191-196, 2014.

(要約): The susceptibility vessel sign on gradient echo-type-T2*-weighted imaging is a well-known marker of arterial occlusion. Stagnant flow in front of the middle cerebral artery (MCA) occlusion sites may contribute to the intra-arterial, high-intensity signal on arterial spin labeling magnetic resonance imaging (MRI), making it another potential marker of MCA occlusion. We compared the intra-arterial, high-intensity signal and susceptibility vessel sign in patients with symptomatic MCA occlusion and patients without major vessel occlusion. We identified transient ischemic attack or ischemic stroke patients with (1) 3-T MRI performed within 24 h after clinical onset including arterial spin labeling, T2*-weighted imaging, and magnetic resonance angiography (MRA) and (2) either having MCA occlusion (n = 34 patients) or without major vessel occlusion (n = 24 patients). The intra-arterial, high-intensity signal was defined as an enlarged circular or linear bright hyperintensity within the artery. The susceptibility vessel sign was defined as an enlarged spot of hypointensity within the MCA, in which the diameter of the hypointense signal within the vessel exceeded the contralateral vessel diameter. The presence or absence of the intra-arterial, high-intensity signal and susceptibility vessel sign were assessed, along with their inter-rater agreement and consistency with the presence of MCA occlusion on MRA. The intra-arterial, high-intensity signal was detectable in 30 patients (52%), and susceptibility vessel sign was observed in 17 patients (29%). The sensitivity of the intra-arterial high-intensity signal was significantly higher than that of the susceptibility vessel sign (88% vs. 50%; p < 0.05). The accuracy of the intra-arterial high-intensity signal was also higher than that of the susceptibility vessel sign (93% vs. 71%; p < 0.05). The intra-arterial high-intensity signal was situated in the proximal regions of the susceptibility vessel sign on T2*WI within the MCA. Neither the intra-arterial high-intensity signal nor the susceptibility vessel sign was observed in patients without major vessel occlusion. Inter-rater agreement was good for intra-arterial high-intensity signal detection (κ = 0.73) and moderate for susceptibility vessel sign detection (κ = 0.47). The presence or absence of the intra-arterial high-intensity signal was highly consistent with that of MCA occlusion on MRA (κ = 0.74). The intra-arterial high-intensity signal on arterial spin labeling appears to be useful to identify the presence of acute MCA occlusion and may be associated with stagnant flow in front of occlusion sites. The intra-arterial high-intensity signal may also be used to identify the occlusion site.

Reversibility of ischemic findings on 3-tesla magnetic resonance T2(*)-weighted image after recanalization,
The Journal of Medical Investigation : JMI, Vol.61, No.1,2, 190-196, 2014.

(要約): Ischemic vessel signs (IVS) can be detected on 3-tesla T2(*)-weighted magnetic resonance images as a vessel enlargement at the territory of acute ischemia caused by major vessel occlusion or stenosis. Here, we studied changes in IVS before and after recanalization by the administration of intravenous recombinant tissue plasminogen activator (IV rtPA), carotid artery stenting or percutaneous transluminal angioplasty in patients with major vessel occlusion or stenosis. We performed magnetic resonance imaging for all patients treated by IV rtPA at the time of admission, shortly after and 24-72 hours after treatment with IV rtPA. We reviewed the IVS to assess its natural course of IVS by assessing patients who did not recanalize. IVS tended to disappear after recanalization. Conversely, in patients without recanalization, IVS did not disappear shortly after IV rtPA; rather, it disappeared 24-72 hours after IV rtPA, especially in the presence of complete infarction. Recanalization by IV rtPA or endovascular treatment contributed to improved clinical deficits or the prevention from further progression. IVS can be a parameter of misery perfusion and an important factor to detect the patients who have an indication of treatment for recanalization.

80歳以上の破裂脳動脈瘤の治療成績,
脳卒中の外科, Vol.42, No.1, 42-46, 2014年.

(要約): While the number of elderly patients who presented with aneurysmal subarachnoid hemorrhage (SAH) has been increasing, its optimal management in that population remains controversial. Therefore, we retrospectively reviewed the treatment outcomes in 49 consecutive patients aged between 80 and 94 years who presented with SAH. The neurological World Federation of Neurological Surgeons (WFNS) grade at the time of admission was Grade I in 7, Grade II in 11, Grade III in 8, Grade IV in 13, and Grade V in 10 patients. Of the 49 patients, 28 underwent coil embolization, and 7 (25%) had a favorable outcome (mRS: 0-2) at discharge, while in 21 (75%) the outcome was poor (mRS: 3-6). Six patients underwent clipping; the outcome was favorable in one patient (17%) and poor in 5 (83%). Of 15 patients under conservative therapy none had a favorable outcome. A low WFNS grade (I-II) was significantly associated with a favorable outcome (p<0.05). Although the treatment outcome in elderly patients with SAH was poor, radical treatment of ruptured aneurysms should be considered if their WFNS grade is low.

Brush sign on 3-T t2*-weighted MRI as a potential predictor of hemorrhagic transformation after tissue plasminogen activator therapy,
Stroke, Vol.45, No.1, 274-276, 2014.

(要約): The brush sign (BS) is the enlargement of medullary veins on 3-T T2*-weighted MRI seen in patients with ischemic stroke because of major cerebral artery occlusion. However, the clinical relevance of BS in patients with acute stroke remains unclear. We assessed the correlation between detecting BS with the development of hemorrhagic transformation after intravenous thrombolysis. We enrolled consecutive patients with M1 or M2 occlusion treated with intravenous tissue plasminogen activator. We classified the patients into 2 groups: the group positive for BS (P-BS) and the group negative for BS (N-BS). We investigated the differences in MRI findings and the clinical outcome between the 2 groups. The subjects consisted of 36 patients (19 men; mean age, 74.7 years). Twenty-one patients (58%) had M1 occlusion, and 15 (42%) had M2 occlusion. Twenty-five patients (69%) were classified into the P-BS group and 11 (31%) into the N-BS group. Recanalization was observed in 15 (60%) and 10 (90%) patients in the P-BS and N-BS groups, respectively (P=0.116). Hemorrhagic transformation on MRI was observed more frequently in the P-BS group than in the N-BS group (64% versus 18%; P=0.027). A good outcome (mRS, 0-1) at discharge was found in 24% of patients in the P-BS group and in 45% of patients in the N-BS group (P=0.152). A multivariate logistic regression analysis revealed that the presence of BS (odds ratio, 9.08; 95% confidence interval, 1.4-59.8; P=0.022) was independently associated with hemorrhagic transformation. BS may predict the development of hemorrhagic transformation in patients with acute stroke treated with intravenous tissue plasminogen activator.

Evaluation of Serial Intra-Arterial Indocyanine Green Videoangiography in the Surgical Treatment of Cranial and Craniocervical Junction Arteriovenous Fistulae: A Case Series,
Operative Neurosurgery, Vol.25, No.3, 292-300, 2023.

(要約): Intravenous indocyanine green (IV-ICG) videoangiography is commonly performed to detect blood flow in the microscopic view. However, intra-arterial ICG (IA-ICG) videoangiography provides high-contrast imaging, repeatability within a short period of time, and clear-cut separation of the arterial and venous phases compared with IV-ICG. These features are useful for detecting retrograde venous drainage (RVD) and shunt occlusion in arteriovenous fistulae (AVF) surgery. This study aimed to investigate whether IA-ICG videoangiography can be repeatable within a short period of time and be useful for detecting RVD and shunt occlusion in cranial- and craniocervical junction (CCJ)-AVF surgery. Between January 2012 and December 2022, 50 patients were treated with endovascular or surgical intervention for cranial- and CCJ-AVF at Tokushima University Hospital. Of these, 5 patients (6 lesions) underwent open surgery with IA-ICG videoangiography in a hybrid operating room. We analyzed the data of these 5 patients (6 lesions). There were 4/patient (median, range 2-12) and 3.5/lesion (median, range 2-10) intraoperative IA-ICG runs. IA-ICG videoangiography detected RVD in all patients. Clearance of IA-ICG-induced fluorescence was achieved within 30 seconds in all patients at each region of interest. After the disconnection of the fistulae, IA-ICG videoangiography and intraoperative digital subtraction angiography (DSA) confirmed the disappearance of RVD in all patients. There were no complications associated with IA-ICG videoangiography. This study showed that IA-ICG videoangiography is repeatable within a short period of time before and after obliteration and can be useful for detecting RVD and shunt occlusion in cranial- and CCJ-AVF surgery. IA-ICG videoangiography also allows intraoperative DSA studies in a hybrid operating room. Considering the recent advancements in hybrid operating rooms, combining IA-ICG videoangiography with intraoperative DSA is a useful strategy for cranial- and CCJ-AVF surgery.

徳島大学病院脳卒中センターでの内頚動脈急性閉塞に対する治療戦略,
四国医学雑誌, Vol.70, No.5,6, 167-172, 2014年.

(要約): Objective : Strokes related to acute internal carotid artery (ICA) occlusion are associated with extremely poor prognosis. Recently, some studies have reported that the prognosis has been getting better by treating with intra-arterial endovascular therapy. We sought to evaluate clinical outcomes in patients with acute ischemic stroke attributable to ICA occlusion treated with intraarterial endovascular therapy or otherwise. Methods : We reviewed 44 patients who underwent treatment with intra-arterial endovascular therapy or otherwise in our stroke care unit (SCU) from January, 2011 to May, 2014. We compared the prognosis of patients in the 2 treatment groups (endovascular group, n＝23 vs nonendovascular group, n＝21). Results : The rate of good prognosis (modified Rankin Score of ≦2) was significantly higher in the endovascular group than non-endovascular group (17．4% vs0%，p＝0．045). The rate of patients who had extreme improvements of National Institutes of Health Stroke Scale (NIHSS) ≧8 was higher in the endovascular group than non-endovascular group (30．4% vs14．3%). Concerning the improvement of NIHSS ≧8, recombinant tissue-type plasminogen activator (rt-PA) or the left side ICA occlusion were associated significantly (p＝0．019, p＝0．042, respectively). Although the hypothesis that endovascular therapy could contribute to extreme improvements of NIHSS wasn't proved (p＝0．202), there was one case that NIHSS was dramatically improved from 22 to 0 by endovascular therapy. Conclusions : Intra-arterial endovascular therapy of ICA occlusion might result in improved clinical outcomes for indicated cases.
