Delayed Anterior Choroidal Artery Territory Infarction after Carotid Ligation Surgery with an Extracranial to Intracranial High-flow Bypass for a Large Cavernous Carotid Aneurysm: A Case Report

Abstract

A 65-year-old female presented with right oculomotor nerve palsy due to a large internal carotid artery (ICA) cavernous aneurysm. She underwent ligation of the right ICA with an external carotid artery to middle cerebral artery high-flow bypass (HFB).
