title: Haemodynamics of arteriovenous malformations of the brain and consequences of resection: a review.
abstract: The physiological manifestations of arteriovenous fistulae in humans have been studied since the 18th century. However, confusion regarding concepts of cerebral 'steal', 'normal perfusion breakthrough', and 'congestive hyperaemia' continue. Although the advent of more accurate monitoring of pressures and flows within the brain has provided useful information to help understand some of these proposed pathological hypotheses, disagreement still exists. The purpose of this review is to examine the current physiological data in attempt to explain the clinicopathological manifestations of arteriovenous malformations of the brain and the consequences of their removal.
