title: Remote cerebellar hemorrhage after supratentorial unruptured aneurysmal surgery: report of three cases.
abstract: We report three cases of remote cerebellar hemorrhage that developed after supratentorial unruptured aneurysmal surgery. In all cases, digital subtraction angiography was performed before each operation in order to rule out other vascular abnormalities, especially around the operative field or the posterior circulation. In addition, all patients were screened for any previous history of bleeding tendencies or other related medical disorders. Each patient underwent clipping surgery via the pterional approach. Remote cerebellar hemorrhage was identified on post-operative computed tomographic scans. In all cases, there was no evidence of significant associated long-term morbidity. A consideration of the possible pathophysiologic mechanisms underlying these post-operative remote cerebellar hemorrhages and suggested strategies for avoiding such complications are discussed.
