Carotid Sacrifice via Endonasal Clipping to Treat Carotid Injury in Extended Endoscopic Endonasal Surgery

Abstract Internal carotid artery (ICA) injury is a rare but disastrous complication during extended endoscopic endonasal surgery. The method of ICA sacrifice via endonasal clipping has only been reported in a few cases to treat ICA injury. To provide some technical experience of this method, here the authors present 2 cases of ICA injury during extended endoscopic endonasal surgery with 2-year follow-up. The 2-nostrils/4-hands technique was used to control the active bleeding. Based on the good collateral circulation status and the normal results of intraoperative electrophysiological monitoring, we sacrificed the injured ICAs via endonasal clipping. Both cases had a satisfying tumor resection rate and a good clinical outcome.
