Chronological Changes in Embolization for Cerebral Arteriovenous Malformations: Impact of Endovascular Treatment Device Advancements.

Objective: Although embolization of cerebral arteriovenous malformations (AVM) is widely performed as an adjunctive therapy before microsurgery or radiosurgery, there is no high-level evidence to ascertain its effectiveness. However, the technology for endovascular devices has improved. Therefore, this study aimed to identify the chronological changes in AVM embolization due to advances in endovascular treatment devices.

Endovascular Embolization with n-Butyl Cyanoacrylate for Ruptured Distal Posterior Inferior Cerebellar Artery Dissecting Aneurysm.

Parent artery occlusion is a definitive treatment method for preventing rebleeding of dissecting aneurysms. We herein report a case of a ruptured distal posterior inferior cerebellar artery (PICA) dissecting aneurysm treated with internal trapping using n-butyl-2-cyanoacrylate (NBCA). A 65-year-old man visited our hospital with a complaint of headache and neck pain that began 1 week before his arrival.

Parent Artery Occlusion for Symptomatic Large Internal Carotid Artery Aneurysm with Primitive Trigeminal Artery Variant: A Case Report.

Objective: To report a case of symptomatic large cerebral aneurysm of the internal carotid artery (ICA), associated with a primitive trigeminal artery variant (PTAv), which was treated with a balloon occlusion test (BOT) to evaluate ischemic tolerance.

Case Presentation: A 79-year-old woman was diagnosed with a symptomatic large cerebral aneurysm of the ICA bifurcating the PTAv due to diplopia. After confirming the ischemic tolerance of the perfusion area and PTAv by BOT, we performed ICA parent artery occlusion with selective embolization of the PTAv.

Transient Hemichorea-hemiballism Induced by a Combination of Postprandial Hypotension and Severe Stenosis of the Innominate Artery Concomitant with Left Carotid Occlusion.

Hemichorea-hemiballism (HCHB) due to transient ischemic attacks (TIAs) is rare. An 83-year-old woman had repeated episodes of right-sided HCHB for 3 months. Magnetic resonance (MR) angiography demonstrated occlusion of the left carotid and middle cerebral arteries and severe stenosis of the innominate artery, and 24-hour ambulatory blood pressure monitoring showed a blood pressure decrease of >20 mmHg after each meal.

Hidden Bow Hunter's Syndrome Diagnosed Using Dynamic Cerebral Angiography and Successfully Treated with Spinal Surgery: A Case Report and Review of the Literature.

Hidden bow hunter's syndrome (HBHS) is a rare disease in which the vertebral artery (VA) occludes in a neutral position but recanalizes in a particular neck position. We herein report an HBHS case and assess its characteristics through a literature review. A 69-year-old man had repeated posterior-circulation infarcts with right VA occlusion.

A Case of Acute Embolic Occlusion of the Common Carotid Artery in Which a Giant Thrombus Was Retrieved Using the Parallel Stent Retriever Technique.

Objective: We report a case of embolic occlusion of the common carotid artery (CCA) in which a giant thrombus was retrieved using the parallel stent retriever technique.

Case Presentation: An 84-year-old woman without anticoagulant therapy despite a history of cardioembolic stroke presented to our hospital because of left hemiparesis after developing sudden vision loss in her right eye. Emergency angiography revealed a giant thrombus in the right CCA.

Vestibular dysfunction as cortical damage with amyotrophic lateral sclerosis.

Background: Cortical damage in areas such as the frontal lobe is reported in amyotrophic lateral sclerosis (ALS). However, aside from executive dysfunction, the pathological significance of this cortical damage has yet to be clarified. The present study investigated the effects of cortical damage on vestibular function in ALS.

A cerebral phenotype of chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids: A case report and review of the literature.

CLIPPERS (chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids) is an inflammatory central nervous system disorder that gives rise to brainstem symptoms such as diplopia and articulatory disorders. It shows characteristic "salt-and-pepper" enhancing brainstem lesions on magnetic resonance imaging (MRI) scans. We present an unusual case of CLIPPERS, in which a 29-year-old man initially presented with a seizure.
