Review Case ReportsPostpartum dissecting aneurysm of the superior cerebellar artery--case report.
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. ⋯ 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.

Case ReportsBow hunter's stroke associated with an aberrant course of the vertebral artery--case report.
A 53-year-old male presented with repeated vertebrobasilar insufficiency on turning the head to the left. Angiography revealed severe stenosis of the dominant right vertebral artery at the atlantoaxial level in this position. ⋯ Therefore, decompression was performed at the bony canal, which was the contributing site, and the symptoms improved. Bow hunter's stroke may be caused by atlantoaxial arterial anomalies, so accurate preoperative evaluation of the region is necessary to avoid anatomical confusion at surgery.
