title: [Subarachnoid hemorrhage caused by a dissecting aneurysm of the internal carotid artery: case report and review of the literature].
abstract: A case of subarachnoid hemorrhage (SAH) resulting from a ruptured intracranial dissecting aneurysm of the internal carotid artery (ICA) is reported. A 58-year-old woman presented with headache and vomiting. A CT showed diffuse SAH. A cerebral angiography demonstrated a dissecting aneurysm at the C2 segment of the right ICA. In the present case, trapping with STA-MCA anastomosis was performed and the postoperative course was uneventful. Postoperative follow-up cerebral angiogram detected no aneurysm. SAH caused by the rupture of a dissecting aneurysm of the ICA has been considered rare. To our knowledge, there have been only 29 cases. We discuss the clinical characteristics with a review of the literature.
