Abstract

|
Congenital arteriovenous malformation is one of developmental anomaly of vascular system. Since the lesion consist of abundant vascular component, feeding arteries and draining vessels, most of the lesions show poor demarcation and even show invasion to the adjacent tissues. Because of this characteristics, management of this malformations is troublesome. Selective arterial embolization and excision of the lesion is one of the recommended management. We experienced congenital arteriovenous malformation at the buttock of 18 years old male patient. He had been performed multiple feeding arterial embolization using Histoacryl with lipiodol 2 years ago because of repeated bleeding. But that buttock bleeding recurred 2 years later. After confirmation of the lesion by MRI and angiogram, wide excision and ligation of feeding artery was done. The wound was repaired by posterior thigh flap.
