Excision with restoration of arterial continuity has become the treatment of choice for extracranial carotid aneurysms. Three of the seven cases reported here involved the common carotid artery, and four the internal carotid artery. Technics included excision and primary repair, excision and graft, temporary external or internal shunts, and permanent bypass graft. The one patient who died had congenital absence of a portion of the circle of Willis. The other six patients recovered without neurologic sequelae.
