Numerical Study of Blood Redistribution in the Circle of Willis of Patients With Carotid Artery Stenosis

Stroke is an acute neurological injury in which the blood supply to a part of the brain is interrupted due to either a diminution of cerebral blood flow or a sudden occlusion of a feeding artery. Blood perfusion depends not only on the status of the diseased vessels but also on the patency of collateral pathways. The primary collateral pathway is that provided by the Circle of Willis (CoW).
