Hemodynamic changes are of importance while re-moving large and high-flow arteriovenous malfor-mations (AVM), because a phenomenon called "normal perfusion pressure breakthrough" may occur. In this report, we evaluated hemodynamic changes in 14 cases of high-flow AVM with cerebral angiogram and intraoperative monitoring of cortical-surface blood flow. The criteria we used for high-flow AVM are ; 1) nidus larger than 4 cm, 2) a few large feeders, 3) high-flow shunt in the nidus, and 4) reduced circulation or dilated arteries in the adjacent brain tissue.
