Circle of Willis Collateral Flow Investigated by Magnetic Resonance Angiography [PDF]

open access: yesStroke, 1999
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 (ICA) obstruction. We aimed to investigate the anatomic variation of the CW in patients with severe symptomatic carotid obstructive disease and to analyze diameter changes of
