Geometrical determinants of cerebral artery fenestration for cerebral infarction.
PeerJ
January 2025
Department of Magnetic Resonance Imaging, Hongqi Hospital, Mudanjiang Medical University, Mudanjiang, Heilongjiang, China.
Purpose: Few data are available on the causality of cerebral artery fenestration (CAF) triggering cerebral infarction (CI) and this study aims to identify representative morphological features that can indicate risks.
Methods: A cohort comprising 89 patients diagnosed with CAF were enrolled from a total of 9,986 cranial MR angiographies. These patients were categorized into Infarction Group ( = 55) and Control Group ( = 34) according to infarction events.
Three episodes of basilar tip occlusion necessitating thrombectomies and a vertebral artery sacrifice in a patient with subclavian artery dissection distal to the vertebral artery origin: a case report.
AME Case Rep
October 2024
Department of Diagnostic Imaging, Soroka University Medical Center, Ben-Gurion University of the Negev, Beer-Sheva, Israel.
Background: While acute occlusion of the subclavian artery (SCA) proximal to the vertebral artery (VA) origin is an uncommon but recognized cause of embolic stroke, an occlusion distal to the VA is rare and can be easily overlooked.
Case Description: We describe the clinical presentation and evaluation of a previously healthy 56-year-old woman who experienced four life-threatening posterior circulation strokes within 1 month, three of which led to basilar artery (BA) occlusions requiring thrombectomies. Workup revealed an occlusion of the right SCA located less than 1 cm distal to the VA origin.
Delayed Aneurysm Rupture Following Endovascular Treatment with Contour Device: A Case Report.
Neurointervention
January 2025
Department of Neuroradiology, Neuroscience Institute, Hamad Medical Corporation, Hamad General Hospital, Doha, Qatar.
Delayed rupture of intracranial aneurysms after endovascular treatment is a rare but serious complication. We report the first documented case of late aneurysmal rupture following treatment with a Contour intrasaccular device. A patient in their 60s with a basilar tip aneurysm underwent endovascular treatment using a 14-mm Contour device.
View Article and Find Full Text PDFAberrant anatomical variation of the vertebral artery (VA) from an internal carotid artery (ICA) is considered a rare finding. The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.

J Neurol Surg Rep
January 2025
Department of Neurosurgery and Spine Surgery, Qatif Central Hospital, Qatif, Saudi Arabia.
A rare variant of congenital aqueductal stenosis (CAS) is known as adult-onset CAS, characterized by the emergence of symptoms during adulthood. A 35-year-old man presented complaining of acute-onset headache and vomiting. Magnetic resonance imaging of the brain revealed an acute hydrocephalus due to an aqueductal web.
