We describe five patients with blunt traumatic carotid dissection with delayed clinical presentation that varied from 2 weeks to 6 months.Four patients had severe head injury,and one patient had direct blunt trauma to the neck.Cerebrovascular symptoms developed in four patients.The fifth patient suffered loss of vision as a result of a concurrent giant intracranial dissecting aneurysm.Arteriography demonstrated a"string sign" in two cases and a cervical carotid aneurysm in three;two of the latter also had siphon occlusion,and one of these had a superimposed supraclinoid dissecting aneurysm.One patient was treated by thromboendarterectomy,one by aneurysmorraphy,another by carotid ligation,and the other two patients were treated medically.Mechanisms of injury,forensic problems,and therapeutic options are discussed. |
