Balloon-assisted Onyx Embolization of an Extensive Mandibular Gingival Arteriovenous Malformation: a case report

This is a rare case of mandibular arteriovenous gingival malformations with episodes of spontaneous bleeding and referred to our department for emergent interventional therapy. Onyx was chose as embolic agent due to its specific physical properties and infuse under balloon-assisted technique for good penetration of embolic particles into the nidus and feeders. We present this case and share the experience of this technique. We also describe the technical details, properties of embolic agents and review some literatures in public.
