The circle of Willis is an anastomotic network of arteries surrounding the base of the brain,
providing collateral circulation to prevent ischemia. It has, however, long been established …

Background and Purpose—The circle of Willis (CW) is considered an important collateral
pathway in maintaining adequate cerebral blood flow in patients with internal carotid artery …

High-resolution phase—contrast magnetic resonance imaging can now assess flow in
proximal and distal cerebral arteries. The aim of this study was to describe how total cerebral …

A distributed model of the human arterial tree including all main systemic arteries coupled to
a heart model is developed. The one-dimensional (1-D) form of the momentum and …

Brains were obtained from 1000 medicolegal autopsy subjects of varying ages. The circle of
Wills was examined at the base of the brain. The cerebral vessels were observed with …

In a fetal-type posterior circle of Willis (FTP) there is an embryonic derivation of the posterior
cerebral artery (PCA) from the internal carotid artery (ICA). Besides the fact that a larger area …

Migraine headache is widely believed to be associated with cerebral or meningeal
vasodilatation. Human evidence for this hypothesis is lacking. 3 Tesla magnetic resonance …

Methods Electronic searches were performed using six databases from their inception to
January 2013. Two reviewers independently identified all relevant studies comparing DHCA …

Background and Purpose—The circle of Willis is regarded as the major source of collateral
flow in patients with severe carotid artery disease. The purpose of the present study was to …

The Circle of Willis (CoW) is an important network of arteries connecting major circulations of
the brain. Its vascular architecture is believed to affect the risk, severity, and clinical outcome …
