Treatment of Complex Cerebral Aneurysm Using Extracranial-intracranial Bypass: Case Report

We describe intracranial bypass options employed in direct clipping of the large cerebral aneurysm. The bypass techniques used included STA-MCA bypass (n = 2), radial artery graft (n = 2), ACA-ACA side to side (n = 1), and STA-PCA, STA-SCA bypass (n = 1). We consider the options of vascular reconstruction prior to manipulation of the aneurysm when the patency of the parent artery is unpredictable.
