Background Circulus arteriosus cerebri (CAC), responsible for supplying blood to the brain,
presents anatomical variations that have been associated with both haemorrhagic and …

The Circle of Willis (CoW) is a complex pentagonal network comprised of fourteen cerebral
vessels located at the base of the brain. The collateral flow feature within the circle of Willis …

Progression of carotid stenosis (CS) significantly reduces blood flow in the affected arteries
and alters both proximal and distal hemodynamics. While conventional studies consider …

Background/Aim. The presence of aneurysmal changes on the brain blood vessels has
been subject to numerous research. This study investigated the relation between ruptured …

Objectives: Less ischemic volume and better functional outcome are related with good
cerebral collaterals in ischemic stroke. But the method of assessing collateral circulation is …

Objective: In patients with stenosis of the internal carotid artery (ICA), the presence of
collateral circulatory pathways may be crucial to maintain cerebral perfusion pressure …

Objective This narrative review aims to analyze the role and efficacy of different methods of
intraoperative neuro-monitoring during carotid endarterectomy (CEA). Methods Articles were …

Background Adaptive arterial remodeling caused by flow reduction from downstream
stenosis has been demonstrated in animal studies. The authors sought to determine …

Computed tomography (CT) angiography is the main method for the initial evaluation of
cerebral circulation in acute stroke. A comprehensive CT examination that includes a review …

Background The role of the willisian collaterals during carotid endarterectomies (CEAs) is a
debated issue. The aim of the present work was to test whether an incomplete or non …
