Facial Nerve Injury as a Complication of Endovascular Treatment for Cavernous Dural Arteriovenous Fistula

Abstract

Facial nerve injury following endovascular treatment of cavernous dural arteriovenous fistulae may be caused by ischemia from inadvertent embolisation of vasa nervorum, shearing or compressive forces. We report a case of unilateral facial nerve palsy as a complication of cavernous dural arteriovenous fistula embolisation.
