The successful surgical management of a patient with a traumatic aneurysm of the internal carotid artery (ICA) at the base of the skull and a second traumatic aneurysm of the ipsilateral superficial temporal artery is described. EC-IC bypass was not necessary, and graded occlusion of the ICA was employed. Direct repair was not chosen because of its high risk of distal embolization. Electrophysiologic monitoring techniques are helpful in predicting hemispheric ischemia.
