Treatment of arteriovenous malformations of the mandible by arterial and venous embolization.

High-flow arteriovenous malformations (AVMS) of the mandible, though rare, may cause death from intractable bleeding, usually following a dental extraction [1-3]. Treatment is difficult, as evidenced by the large range of therapies that have been proposed. These include repetitive embolization, embolization andjor surgical resection, and curettage [1 , 4-6). Nevertheless, some authors have described successful AVM embolization with the use of superselective catheterization in direct proximity to the nidus [3, 7, 8]. We report two cases in which arterial embolization was followed by percutaneous transmandibular occlusion of the venous drainage, producing complete disappearance of the AVM with osseous reconstruction.
