Is Routine Intraoperative Angiography in the Surgical Treatment of Cerebral Aneurysms Justified? A Consecutive Series of 147 Aneurysms

Abstract

IA is recommended during the surgical clipping of complex or large aneurysms and some middle cerebral artery aneurysms. High cost-benefit ratio, false-negative rate, and moderate risk, however, preclude routine use. With future technological advances, IA may warrant broader use by replacing postoperative studies in the neurosurgical management of intracranial aneurysms.
