Mandibular arteriovenous malformations (AVMs) are rare lesions which can present with life-threatening haemorrhage. Endovascular embolisation can be life saving for these patients. We discuss a patient of mandibular AVM, who initially presented with reports of massive oral bleeding. The lesion was only partially embolised via transarterial route, as the nidus could not be penetrated completely. In view of rebleeding within 72 hours from the same site, a second embolisation procedure was done via combined, transarterial and transvenous approaches. Coils and onyx were used as embolising agents. Complete embolisation was achieved via combined approach. No further bleeding episodes were seen at 1-year follow-up. Endovascular embolisation of mandibular AVMs can be technically challenging and, hence, a sound knowledge of the anatomy as well as the possible modification of technique is essential to achieve complete obliteration of the lesion and to maximise the benefit of embolisation and to avoid major radical surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
