Traumatic bilateral dissections of the internal carotid artery: an infrequent diagnosis not to be missed.

We report the case of two patients involved in a car crash and victims of multiple injuries. The diagnosis of bilateral dissection of the internal carotid arteries was only evoked belatedly in view of the increase of the neurologic symptoms. They benefitted from anticoagulant treatment. The clinical evolution was good. Dissection of both carotid arteries from blunt head or neck trauma has been reported but is unusual. Diagnosis and treatment are discussed.
