Distal Posterior Cerebral Artery Revascularization in Multimodality Management of Complex Peripheral Posterior Cerebral Artery Aneurysms: Technical Case Report

Abstract

De novo distal P2 sacrifice, advocated for treating peripheral PCA aneurysms, leads to visual field deficits in some patients. Revascularization of the distal segment of the PCA, less technically demanding than bypass to other PCA segments, preserves blood flow, thus sparing vision in this subset of patients.
