Pseudoaneurysm of the cervical internal carotid artery secondary to blunt trauma.

A case of pseudoaneurysm in the extracranial internal carotid artery secondary to blunt trauma is presented to corroborate reports of aneurysmal formation in association with ipsilateral mandibular fracture. Because of the possibility of rupture or the development of neurologic symptomatology due to embolization, pseudoaneurysms of the cervical internal carotid artery should be repaired. We recommend use of the autogenous interposition vein graft to restore arterial continuity.
