Traumatic aneurysm associated with fibrointimal proliferation of the common carotid artery following blunt trauma: case report.

Late neurologic symptoms following blunt trauma to the neck and upper torso were evaluated with duplex scanning of the carotid arteries and the diagnosis of a traumatic aneurysm of the common carotid artery with an associated stenosis was made. Resection and an end-to-end anastomosis resulted in an excellent outcome. Carotid aneurysm following blunt trauma is unusual and duplex scanning facilitated the diagnosis. Duplex scanning is useful in the evaluation of the carotid arteries in patients with posttraumatic neurologic symptoms.
