title: [Surgical and endovascular treatment for superior cerebellar artery aneurysms: report of two cases].
abstract: Aneurysms located on the superior cerebellar artery (SCA) are uncommon and their presentation, natural history, and clinical management are poorly understood. Reports related to the endovascular or surgical management of SCA aneurysms are rare. Herein, we report two cases of SCA aneurysm. The first is that of a 70-year-old woman who presented with subarachnoid hemorrhage (SAH). Surgical treatment (neck clipping) of the ruptured SCA aneurysm was performed, and the flow of the parent artery disappeared. The second is that of a 69-year-old woman with an unruptured SCA aneurysm who underwent endovascular surgery to occlude the parent artery. Neither patients exhibited any additional neurological deficits. SCA aneurysms often have either relatively wide or undefinable necks, so it is difficult to preserve the parent artery. According to several surgical reports, occlusion of the SCA appears well tolerated for a variety of reasons.
