High-Flow Bypass with Internal Carotid Artery to Middle Cerebral Artery Bypass Using Radial Artery Graft Through the Supramandibular-Subzygomatic Route for Giant Internal Carotid Aneurysm: Technical Case Report

This case provided 2 new methods for high-flow bypass: RA graft route and the anastomosis of the ICA in carotid bifurcation. To our knowledge, this is the first case report of a high-flow bypass with a tunnel created for the RA graft (supramandibular-subzygomatic route) and an ICA-RA-M2 anastomosis.
