Surgical treatment following huge arteriovenous malformation extending from the lower lip to the chin: combination of embolization, total resection, and a double cross lip flap.

摘要

A huge arteriovenous malformation (AVM) extending from the lower lip to the chin was surgically resected and the area was reconstructed during the same surgery in three patients. To control hemorrhage during surgery, a radiologist performed embolization of major arteries in the lesion 2 or 3 days before the surgery. After total resection of the AVM, facial reconstruction was performed by using a double cross lip flap from the upper lip and a local skin flap from the lower jaw. As a result, bleeding was well controlled, the AVM was totally resected, and satisfactory functional and esthetic results were obtained.
