title: Traumatic aneurysm of the supraclinoid internal carotid artery-case report-.
abstract: A 23-year-old male was admitted after a motor vehicle accident with acute epidural hematoma, diffuse subarachnoid hemorrhage (SAH) in the basal cistern, and fractures at the anterior cranial base. Angiography revealed an aneurysm of the right supraclinoid internal carotid artery (ICA). His consciousness suddenly worsened on the 23rd day. Expansion of the SAH in the basal cistern and two hump aneurysms were detected. He underwent endovascular embolization of these aneurysms and the right ICA with Guglielmi detachable coil. Traumatic aneurysms are difficult to diagnose in the early period after injury and are associated with a high mortality. Endovascular treatments for traumatic aneurysms have lower mortality rate, and can be performed under local anesthesia.
