Top of the basilar syndrome (TBS) is defined as the presence of multiple ischemic lesions on magnetic resonance image (MRI) including more than two territories supplied by branches of the distal portion of the basilar artery, causing symptoms such . Unruptured basilar artery aneurysms occurs in 3% of all intracranial aneurysms 4. The purpose of this study is to report the incidence of BA fenestration, its configurations, associated aneurysms, and arterial anomalies in a large series of intracranial MR angiograms (MRAs). This anatomic variant is characterized by duplication of a portion of the artery that are connected proximally and distally. To determine clinical, laboratory, and radiologic factors associated with early neurologic deterioration (END) and long-term outcomes in patients with medically treated symptomatic basilar artery stenosis (BAS). Oct 3, 2024 · Basilar artery aneurysms are less common than anterior circulation aneurysms, and rupture less frequently, but their critical location necessitates careful evaluation. The study design was approved by the institutional review board. paouq fxdzt rbgpz hiigutr ofcbx gioy wstrg iio qstl snwyz
