Background and Objectives: The published literature highlights the fact that the integrity of
the Circle of Willis has a direct impact on stroke outcome, especially in cases of distal …

Background: The main scope of this paper is to investigate the prevalence of the anatomical
variants of the circle of Willis (CoW) in the Romanian population through magnetic …

For patients with symptomatic unilateral internal carotid artery (ICA) occlusion, impaired
cerebrovascular reactivity (CVR) indicates increased stroke risk. Here, the role of collateral …

Purpose To confirm and illustrate the great variability of morphology of the Cerebral Arterial
Circle (CAC)—also commonly called “Circle of Willis”—in current clinical Computed …

Purpose Acute ischemic stroke is a life-threatening emergency caused by an occlusion of a
cerebral artery through a blood clot. Aspiration thrombectomy is an endovascular therapy for …

Background The circle of Willis (COW) is part of the brain collateral system. The absence of
COW segments may affect functional outcome in patients with ischaemic stroke undergoing …

Background Catheter size, location and circle of Willis anatomy impact the flow conditions
during interventional stroke therapy. The aim of the study was to systematically investigate …

Background: Acute cerebral artery occlusion is a common disease with high morbidity and
mortality. At present, the commonly used mechanical thrombectomy schemes are …

Background and Objectives: Contralateral A1 and AComA aplasia/hypoplasia are critically
important in distal ICA T occlusion as the protective collateral blood supply from the circle of …

Purpose: Thromboembolic occlusion of the middle cerebral artery with tandem occlusion of
the internal carotid artery is a life-threatening condition with unfavorable neurological …
