Interobserver Agreement in Scoring Angiographic Results of Basilar Artery Occlusion Stroke Therapy.

AJNR Am J Neuroradiol 2021 Jun 11. Epub 2021 Jun 11.

Department of Interventional Neuroradiology (Francis Turjman), Hospices Civils de Lyon, Lyon,France.

Background And Purpose: The modified TICI Infarction grading system is a metric currently used to evaluate angiographic results of thrombectomy for large-vessel occlusion in ischemic stroke. Originally designed for evaluating MCA territories, it is currently used for other vessel occlusions, including the posterior circulation. We postulate that the modified TICI use for the posterior circulation is not accurate due to the different vascular territories supplied by vertebrobasilar vasculature, making grading more complex.

Bilateral Vertebral Artery Vasculitis-A Rare Manifestation of Giant Cell Arteritis and a Difficult Diagnosis Made Possible by 2-[F]FDG PET/CT.

Diagnostics (Basel) 2021 May 14;11(5). Epub 2021 May 14.

Department of Ophthalmology, Rigshospitalet, University of Copenhagen, 2600 Glostrup, Denmark.

Giant cell arteritis (GCA) is the most common form of large vessel vasculitis. GCA is a medical and ophthalmological emergency, and rapid diagnosis and treatment with high-dose corticosteroids is critical in order to reduce the risk of stroke and sudden irreversible loss of vision. GCA can be difficult to diagnose due to insidious and unspecific symptoms-especially if typical superficial extracranial arteries are not affected. Read More

Department of Neurology, Korea University Ansan Hospital, Korea University College of Medicine, Ansan, Republic of Korea.

Rationale: Free-floating thrombi in the intracranial artery are rare. We report a case of a free-floating and spinning thrombus caused by turbulent flow distal to the basilar artery stenosis. We compare thrombus changes in a series of images according to time and describe the approach to treatment and thrombosis resolution. Read More

Impact of revascularization therapies on outcome of posterior circulation ischemic stroke: The Indo-US stroke project.

J Neurol Sci 2021 May 18;427:117499. Epub 2021 May 18.

Department of Neurology, Stroke Service, Massachusetts General Hospital, Boston, USA.

Introduction: Posterior circulation strokes (PCS) have been less extensively studied than anterior circulation strokes (ACS), especially regarding revascularization therapies. We analyzed the differences in baseline stroke characteristics, revascularization therapy and 3-month outcomes between PCS and ACS in a large prospective multicentre Indian stroke registry.

Methods: Patients with acute ischemic stroke recruited in the Indo-US collaborative stroke project from January 2012 to August 2014 were classified into PCS and ACS based on imaging-confirmed infarct location. Read More

Frequency, Determinants, and Outcomes of Emboli to Distal and New Territories Related to Mechanical Thrombectomy for Acute Ischemic Stroke.

Stroke 2021 May 20:STROKEAHA120033377. Epub 2021 May 20.

Department of Neurology, UCLA, Los Angeles, CA. (D.L., M.N., L.S., N.R., J.H., S.S., J.L.S.).

Background And Purpose: Clot fragmentation and distal embolization during endovascular thrombectomy for acute ischemic stroke may produce emboli downstream of the target occlusion or in previously uninvolved territories. Susceptibility-weighted magnetic resonance imaging can identify both emboli to distal territories (EDT) and new territories (ENT) as new susceptibility vessel signs (SVS). Diffusion-weighted imaging (DWI) can identify infarcts in new territories (INT). Read More

A Pre-Interventional Scale to Predict Atherosclerotic Thrombosis in Acute Vertebrobasilar Artery Occlusion Patients.

Front Neurol 2021 7;12:648081. Epub 2021 Apr 7.

Department of Neurology, Jinling Hospital, Medical School of Southeast University, Nanjing, China.

Determining the occlusion mechanism before endovascular treatment (EVT) is of great significance for acute large vessel occlusion patients. We aimed to develop and validate a simple pre-EVT scale with readily available variables for predicting atherosclerotic thrombosis (ISAT) in acute vertebrobasilar artery occlusion (VBAO) patients. Consecutive patients were retrieved from Nanjing Stroke Registry Program between January 2014 and December 2019 as a derivation cohort. Read More

Bilateral Vertebral Artery Hypoplasia and Fetal-Type Variants of the Posterior Cerebral Artery in Acute Ischemic Stroke.

Front Neurol 2021 8;12:582149. Epub 2021 Apr 8.

Department of Neurology, Chung Shan Medical University Hospital, Taichung, Taiwan.

Unilateral vertebral artery hypoplasia is considered a risk factor for posterior circulation infarction. Despite the increasing attention on unilateral vertebral artery hypoplasia, few studies have discussed bilateral vertebral artery hypoplasia, its influence on stroke, or its collateral supply from the circle of Willis. We aimed to identify its characteristics, stroke pattern, and unique ultrasonographic and brain imaging findings. Read More

Acute Dizziness, Vertigo, and Unsteadiness.

Neurol Clin 2021 05 30;39(2):373-389. Epub 2021 Mar 30.

Department of Neurology, Lahey Hospital and Medical Center, 41 Mall Road, Burlington, MA 1805, USA; Tufts University School of Medicine, Burlington, MA, USA.

Vestibular symptoms, including dizziness, vertigo, and unsteadiness, are common presentations in the emergency department. Most cases have benign causes, such as vestibular apparatus dysfunction or orthostatic hypotension. However, dizziness can signal a more sinister condition, such as an acute cerebrovascular event or high-risk cardiac arrhythmia. Read More

Departments of1Neurosurgery.

Objective: Symptomatic nonsaccular vertebrobasilar aneurysms (NSVBAs) are associated with high rates of aneurysm-related death. Anecdotal evidence suggests that brainstem infarction may be a harbinger of aneurysm rupture.

Child Development Centre, Pediatric Hospital, Centro Hospitalar e Universitário de Coimbra, Coimbra, Portugal. Electronic address:

Cerebrovascular events in pediatric population are very rare. Up to 30% may result from varicella zoster (VZV) arteriopathy, usually as a delayed complication of varicella primary infection. The most typical pattern includes involvement of anterior brain circulation arteries, probably by VZV migration from the trigeminal ganglia. Read More

Endovascular recanalization for non-acute basilar artery occlusions with progressive or recurrent ischemic symptoms: a multicenter clinical experience.

J Neurointerv Surg 2021 Mar 4. Epub 2021 Mar 4.

Department of Interventional Neuroradiology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Background: There is no consensus on the optimal treatment of non-acute basilar artery occlusion (BAO), and endovascular recanalization still poses a therapeutic challenge for these patients. We report a multicenter clinical experience of endovascular recanalization for symptomatic non-acute BAO and propose an angiographic grouping to determine which patient subgroup most benefits from this treatment.

Methods: Forty-two patients with non-acute BAO with progressive or recurrent vertebrobasilar ischemic symptoms who underwent endovascular recanalization were retrospectively analyzed from January 2015 to December 2019. Read More

Basilar artery occlusion presenting as sudden bilateral deafness: a case report.

J Med Case Rep 2021 Mar 2;15(1):111. Epub 2021 Mar 2.

Department of Neurosurgery, Tokushima Municipal Hospital, 2-34, Kitajyosanjima-cho, Tokushima, 770-0812, Japan.

Background: Most sudden-onset hearing loss is due to otolaryngologic- and very rarely to cerebrovascular disease. We report a woman with sudden bilateral sensorineural hearing loss. This case suggests that even in the absence of brainstem or cerebellar signs, magnetic resonance imaging (MRI) and MR angiography (MRA) should be performed since such studies may reveal signs of life-threatening vertebrobasilar artery occlusion.
