Congenital arteriovenous malformation of the head and neck.

A discussion of congenital arteriovenous malformation of the head and neck based on five patients followed from three to twenty years is presented. Definition of the lesion and its progression as followed by angiography is described. The poor response to surgery is ascribed to the ischemic nature of the area of involvement. The concept of supplying normal tissue with normal vascularity to the involved area is advocated.
