The authors report two cases of huge arteriovenous malformations in the head and neck regions treated successfully with preoperative superselective transarterial embolization and resection followed by a free perforator flap transfer. Based on the authors' previous cases, en block mass resection of the malformation was possible with bleeding of less than 150 ml. The massive defects could be repaired with free perforator flaps using an anterolateral thigh flap and a deep inferior epigastric artery perforator flap. One patient who lost facial muscle underwent reconstruction by simultaneous muscle transfer, and both patients regained acceptable cosmetic appearance and dynamic facial function. Now, more than 4 to 7 years after surgery, the patients have shown no reexpansion of the malformation. The important points of this treatment are complete embolization to accomplish total resection with minimal bleeding, free flap transfer to prevent postoperative reexpansion or recurrence of arteriovenous malformations, and the selection of recipient vessels because of arterial embolization in part of the lesion.
