Treatment of mandibular arteriovenous malformation by transvenous embolization: A case report

Background. Arteriovenous malformations (AVMs) of the mandible are relative ly rare and potentially life-threatening lesions. Treatment is usually diff icult. This study presents a case with high-flow AVM of the mandible in whi ch most of the AVM were occluded by transvenous coil embolization. Methods. Transvenous embolization using several size 57 microcoils and 3 Gi anturco coils was performed through a right femoral vein access. The small residual AVM was occluded by superselective transarterial injection of cyan oacrylate. Results. Angiography after embolization showed almost complete obliteration of AVM. Panoramic radiograph 2 years after treatment confirmed reossificat ion. There was no recurrence of the symptoms in a follow-up evaluation 2 ye ars later. Conclusion. Transvenous coil embolization may be a safer and more effective method in the treatment of mandibular AVM. (C) 1999 John Wiley & Sons, Inc . Head Neck 21: 574-577, 1999.
