Cerebral arterial fenestration associated with stroke and other cerebrovascular diseases

In this study, we aimed to investigate the imaging characteristics of cerebral fenestrations, the clinical characteristics of fenestrations complicated with cerebrovascular diseases, and the correlation between fenestrations and cerebrovascular diseases. Methods We reviewed the magnetic resonance imaging and computed tomography (CT) imaging findings of patients with cerebrovascular fenestrations in the Third Affiliated Hospital of Soochow University from January 2016 to December 2020, mainly focused on the shape and location of fenestrations. According to the location of fenestrated arteries, patients were divided into the internal carotid arterial system (ICAS) group and the vertebrobasilar arterial system (VAS) group. For patients complicated with cerebrovascular diseases, detailed data about the demographics and clinical characteristics were recorded. Stroke patients with injured lesions located in the territories of fenestrated arteries were further screened out and analyzed. Moreover, the proportions of cerebrovascular diseases including stroke between the ICAS group and the VAS group were compared. Results A total of 280 cerebrovascular fenestrations were found in 274 patients (six patients had two fenestrations). The most frequently involved vessels were the anterior cerebral artery (123/280), the basilar artery (76/280) and the vertebral artery (35/280). As to the shape of fenestrations, slit-like fenestrations accounted for 63.2% (177/280), followed by ...
