title: Postpartum dissecting aneurysm of the superior cerebellar artery--case report.
abstract: A 37-year-old female with toxemia of pregnancy suffered sudden headache and loss of consciousness on the day following a cesarean delivery. Computed tomography revealed subarachnoid hemorrhage (SAH). Vertebral angiography revealed a fusiform dilatation near the origin of the right superior cerebellar artery (SCA) with distal luminal narrowing. She underwent surgery within 24 hours of the ictus. A SAH clot was carefully removed from the prepontine cistern, and subadventitial discoloration was seen in the wall of the right SCA just distal to the aneurysmal protuberance (rupture site). The dissecting aneurysm was treated with body clipping by directly clipping the rupture site and with additional wrapping of the proximal SCA, including the aneurysmal protuberance and discolored site. The postoperative clinical course was uneventful. Postoperative angiography revealed complete obliteration of the aneurysm and patency of the SCA. Therapeutic intervention should be considered for patients with ruptured dissecting aneurysm who present with recurrent SAH.
