The risk factors for intraprocedural rupture (IPR) of unruptured intracranial aneurysms (UIAs) and the outcomes IPR itself are unclear. This study was performed to identify independent IPR.We retrospectively evaluated medical records radiologic data 1375 patients (1406 UIAs) who underwent coil embolization from January 2001 October 2016.IPR occurred in 20 (1.4%). Univariate analyses showed that rate significantly higher treatment with a small dome size, anterior communicating artery (AcomA)...
ObjectivesAs the number of patients with left ventricular assist device (LVAD) implantation has been increasing, treatment LVAD-related ischemic stroke is becoming a critical issue. We sought to clarify features mechanical thrombectomy in large vessel occlusion.MethodsIn multi-center, retrospective case-control study, we compared 20 strokes 33 non-LVAD strokes, all which had occlusion anterior circulation treated thrombectomy. A comparative histopathological examination retrieved thrombi was...
Background: Chronic subdural hematoma (CSDH) of the posterior fossa is uncommon in adults.Only a few cases have been reported, and most these were secondary to head injury or anticoagulant therapy.We herein describe case successful surgical treatment CSDH after removal large supratentorial infratentorial dermoid cyst.Case Description: A 71-year-old woman underwent left cyst via transzygomatic approach.Three years, 6 months surgery, screening computed tomography revealed regions.Four later,...
The differences in clinical outcomes between endovascular coiling (EC) and surgical clipping (SC) patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH) are controversial. Therefore, this study aimed to evaluate whether EC is superior SC identify risk factors aSAH.We used data from the "Predict for Outcome Study of SubArachnoid Hemorrhage." World Federation Neurological Societies (WFNS) grade III-V aSAH was defined as aSAH, unfavorable (modified Rankin Scale scores 3-6) were...
To describe our initial experience with the Versi Retriever for mechanical thrombectomy in patients acute ischemic stroke.This study is a single-center, single-arm, first-in-man registry under institutional review board control to evaluate efficacy and safety of new stent retriever, Retriever. Patients stroke were consecutively enrolled between September November 2017. The clinical procedural data retrospectively analyzed. angiographic result after procedure was self-graded based on...
Objective: Recently, dual-antiplatelet therapy (DAPT) including clopidogrel (CLP) with endovascular treatment for unruptured cerebral aneurysm has been widely accepted. However, patients who are poor metabolizers of CLP (CLP-PMs) more frequent in East Asians than Caucasians, and an adequate antiplatelet effect may not be achieved a normal dose such patients. Prasugrel, which is novel thienopyridine drug that less likely to poorly metabolized CLP, used percutaneous coronary intervention, but...
Various surgical treatments are available for occlusive subclavian and common carotid artery diseases. Nevertheless, to date, when cerebral endovascular treatment is utilized, revascularization via direct surgery may be required. This study reported five symptomatic cases of CCA SCA stenotic lesions that were expected challenging treat with treatment. We performed artery-common or internal bypass using artificial blood vessels saphenous vein grafts in patients steal syndrome, occlusion,...
OBJECTIVE The authors sought to compare methods of measurement for venous phase delay (VPD) or mean stump pressure (MSTP) rank their potential predict ischemic tolerance during balloon test occlusion in the internal carotid artery, exploring a more correlative and convenient way measure cerebral blood flow (CBF) that could be utilized even acute institutions not adequately equipped CBF test. METHODS X-ray angiography perfusion analysis using diagnostic digital subtraction (DSA) equipment...
Objective: Intracranial hemorrhage (ICH) after endovascular revascularization (ER) for acute ischemic stroke is associated with poor outcome. In this study, we examined the risk factors postoperative ICH in patients who underwent ER our hospital.
脳動静脈奇形(arteriovenous malformation:AVM)のfeeder遠位部に形成されたflow-related aneurysm(distal FA)は破裂急性期に自然血栓化することがまれにあるが,その後の自然経過に関しては不明な点が多く,これまでに再開通に関連した報告はない.今回,破裂distal FAが自然血栓化後に再開通した症例を経験したので報告する.
Surgical treatments for moyamoya disease (MMD) include direct revascularization procedures with proven efficacy, example, superficial temporal artery (STA) to middle cerebral (MCA) bypass, STA anterior occipital (OA) MCA or OA posterior bypass. In cases poor development of the parietal branch STA, auricular (PAA) is often developed and can be used as bypass donor artery. this report, authors describe double performed using only PAA in initial surgery MMD.In authors' institution, MMD...
Patients with pediatric moyamoya disease (PMMD) showing recurrent symptoms or decreased cerebral blood flow after initial revascularization therapy may require additional to improve their clinical condition. The authors evaluated the and hemodynamic benefits of an occipital artery (OA)-middle (MCA) bypass for patients PMMD who have undergone procedure.
BACKGROUND Gamma Knife radiosurgery (GKRS) is a safe and effective treatment, but it has risk of bleeding. Herein, the authors describe their experience with some patients who required surgical removal cerebral arteriovenous malformations (AVMs) located mainly in eloquent areas brain after GKRS, they consider advantages GKRS. OBSERVATIONS Twelve had undergone AVMs GKRS at Tokyo Women’s Medical University between April 2013 July 2019 were selected for analysis. All participants underwent as...
BACKGROUND Unlike in aneurysms of the adult-type posterior cerebral artery (PCA), fetal-type PCA, parent occlusion (PAO) results vascular insufficiency and major ischemic strokes. Preservation or reconstruction PCAs is necessary to prevent these complications. Furthermore, it select an appropriate bypass method approach for revascularization PCA. OBSERVATIONS The authors report 2 cases that were successfully treated with PAO revascularization. A 38-year-old man a large unruptured right PCA...
Kissing aneurysms refer to the condition in which two cerebral with separate necks are contact each other. At present, there is scarce information on kissing occurring near vertebral artery (VA)-posterior inferior cerebellar (PICA). We report first case of VA-PICA and nonbranched PICA aneurysms, were successfully treated contralateral stenting after anchor coil technique using microcatheters. A 64-year-old woman was diagnosed a left aneurysm (5.5 mm) an adjacent small (2.5 aneurysmal walls...
Cavernous malformations of the midbrain have a higher rate hemorrhage and poorer prognosis than vascular other brain areas. Surgical resection these lesions is often necessary to avoid neurological deficits in affected patients. Herein, literature surrounding cavernous was examined, case 48-year-old man with left hemiparesis diplopia caused by incomplete right oculomotor nerve palsy, who diagnosed from malformation, discussed. The lesion expanded gradually on magnetic resonance imaging...
