[Extracranial carotid aneurysms].

Extracranial carotid artery aneurysms occur very seldom. Here will be reported on 15 aneurysms (11 arteriosclerotic, 3 false and 1 dissecting aneurysm). Therapy of choice during the second half of this period was aneurysm exstirpation and PTFE interposition, twice with reinsertion of the external carotid artery. No patient died perioperatively, one permanent and one transient ischemic neurologic deficit occurred. Three lesions of the cranial nerves recovered completely. As to avoid cerebral embolisation each extracranial carotid artery aneurysm should be operated on if possible. This can be managed with tolerable risk and represents an effective embolic prophylaxis.
