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 …

Background There is considerable variation in circle of Willis morphology among the
general population, and these variations have been correlated with risk of aneurysms …

BACKGROUND: Blunt cerebrovascular injury (BCVI) was underdiagnosed until the 1990s
when blunt carotid injuries were found to be more common than historically described …

Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of
recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly …

Abstract The Circle of Willis (COW) is an important collateral pathway to protect the
persistence of cerebral blood perfusion. This study aims to investigate the morphological …

Purpose (1) to estimate the prevalence of Circle of Willis (CoW) variants in patients
undergoing carotid endarterectomy,(2) to correlate these variants to controls and (3) …

Background: During unilateral selective cerebral perfusion (SCP), via canulation of the
brachiocephalic trunk, the brain receives blood only through the right common carotid artery …

Purpose: To prospectively investigate the extent of flow territories of the contralateral internal
carotid artery (ICA) and vertebrobasilar arteries in patients with symptomatic ICA occlusion …

Objective Aimed to evaluate the different anatomical variations of the circle of Willis (COW)
and determined average vessels diameters in general Egyptian population. Patients and …

Purpose: To assess the presence of anterior and posterior collateral pathways in the circle of
Willis in patients with symptomatic carotid artery stenosis (SCAS) and to compare this to …
