The classical Circle of Willis configuration was oberved in only 15 samples (50%). Greater calibers were observed in the arteries of the posterior circulation and multiple linear regression analysis ...

Subarachnoid Hemorrhage - Anterior Cerebral Artery Aneurysm. (Left) Axial CT scan without contrast; (Right) Left internal carotid artery angiogram, Lateral oblique view. On the CT scan, note the ...

The posterior communicating artery (PCOM) is a part of a group of arteries in the brain known as the circle of Willis. The artery connects the internal carotid and the posterior cerebral arteries. Its ...

Willis captures that haunting futility as the hapless James is sent back to the 1990s from 2035 in order to discover the origins of a deadly disease that wiped out five billion people.

Background Collateral circulation is an important determinant of outcome in people with acute ischemic stroke due to large vessel occlusion (LVO). Objective To explore the impact of the circle of ...

Reviewer #1 (Public Review): Cheng et al investigated how vascular cells of the zebrafish Circle of Willis arteries differentiate using live imaging of transgenic zebrafish embryos. They find an ...

Cheng et al. explore the development of the arteries that form the circle of Willis and investigate how blood flow pulsatility influences vascular smooth muscle cell (VSMC) differentiation. Using live ...

The anterior system of the polygon of Willis plays an anastomotic role between the carotid territories and communicates with the posterior system. It ensures adequate cerebral blood flow in the event ...

This study describes a theoretical model of brain cooling by intracarotid cold saline infusion which takes into account redistribution of cold perfusate through the circle of Willis (CoW) and cold ...
