Transarterial onyx embolization of arteriovenous malformation in the infratemporal fossa and parotid region

Abstract

Maxillofacial arteriovenous malformation (AVM) is a rare, but potentially life-threatening entity. Surgical excision usually associates with a high rate of significant blood loss and cosmetic defects. We report a patient who had an AVM involving infratemporal fossa and parotid region, supplied by an enlarged branch of the left ophthalmic artery, cavernous internal carotid artery, middle meningeal artery, and internal maxillary. Successful treatment of this lesion was achieved by transarterial embolization with Onyx. Less invasive transarterial embolization with Onyx is rewarding when curing certain types of maxillofacial AVMs.
