Physiologic Studies of Arteriovenous Anomalies of the Brain

Abstract

Two patients suffering con-vulsive disorders were shown to have large cerebral angio-mata. Cerebral blood flow (a Fick method), a.-v. O2 difference, blood pH, cardiac output (ballistocardiograph), ECG, blood vol. (T 1824 dye), mean arterial pressure and interior jugular bulb pressure (direct method), were estimated for each patient. In both, cerebral blood flow was markedly increased, with increase of cardiac output and size, and decrease of dia-stolic pressure.
