To study the pathophysiology of idiopathic postoperative brain swelling or hemorrhage after arteriovenous malformation resection, termed normal perfusion pressure breakthrough (NPPB), we performed cerebral blood flow (CBF) studies during 152 operations in 143 patients, using the xenon-133 intravenous injection method. In the first part of the study, CBF was(More)
PURPOSE To examine the distribution of arterial hypotension surrounding arteriovenous malformations (AVMs) using a standardized system of vascular zones. METHODS Mean arterial pressures were recorded during superselective cerebral angiography in 96 patients with AVMs (before they underwent liquid polymer embolization) with the use of a system of vascular(More)
In this study the authors determined the effect of papaverine on regional cerebral blood flow (rCBF) in the angiographically normal arteriolar beds of patients with arteriovenous malformations (AVMs) who underwent transfemoral superselective angiography. Middle cerebral artery (MCA) branch vessels were catheterized during 10 procedures performed in nine(More)
