Abstract
✓ Five cases of congenital extracranial arteriovenous malformations are reported. The need for careful preoperative definition of all feeding vessels by selective arteriography is stressed. The radiographic phenomenon of “washout” may preclude the recognition of some arterial feeders at the time of the initial contrast studies. The surgical management of these patients using repeated selective angiography, embolization, and ligation of the major arterial supply, followed by total excision of the malformation, is described.
