title: [Traumatic dissection of the internal carotid artery by a safety belt: a report of two cases].
abstract: Traumatic internal carotid artery dissection secondary to blunt trauma is a rare event accounting for 0.08 to 0.4% of all traumatic lesions. The spectrum of traumatic lesions that can affect the internal carotid artery includes minor lesions like spasm, intimal tears, or mural contusions and serious lesions like pseudoaneurysms and complete occlusion. Delayed clinical presentation is typical and can include headache, hemiparesis, partial Horner's syndrome, and cranial nerve palsy. Embolization secondary to the dissection can have devastating effects because it may cause ischemic stroke. Traumatic internal carotid artery dissection after safety belt trauma is very rare; it is usually due to direct cervical trauma on the side of the shoulder fixation point, which causes external bruising along the pathway of the safety belt. We present two cases of traumatic internal carotid artery dissection with concomitant cerebral infarcts caused by safety belts; we discuss the clinical, diagnostic, and therapeutic aspects of this lesion.
