OBJECTIVE: Arteriovenous malformation (AVM) of the mandible is a rare but potentially life-threatening entity. Traditional treatment involved complex surgical procedures that usually failed to completely cure the malformation without disfigurement and functional difficulties. We report our experience in transarterial and transvenous embolizations of mandibular AVMs using different embolization agents and discuss the potential use of Onyx and new detachable-tip microcatheters. CLINICAL PRESENTATION: Patients presented with progressive mandibular swelling, pain, soft-tissues discoloration and dental misalignment with tooth loosening. INTERVENTION: The AVMs were completely and persistently occluded by endovascular transarterial and transvenous approaches. CONCLUSION: Less invasive endovascular approaches proved to be highly effective in curing certain types of mandibular AVMs. Every malformation requires a tailored endovascular strategy in terms of approach and selection of an embolizing agent.
