The case of postoperative hemorrhage occurring apart from the operative site as a complication of intracranial surgeryis a rare malady, especially when it involves the cerebellum after supratentorial aneurysm surgery. In a review of theliterature, the possible etiologies for cerebellar hemorrhage are: coagulopathy, intraoperative urokinase irrigation, excessivehead rotation on positioning, brain shift due to excessive cerebrospinal fluid(CSF) and epidural hemovac drainage. We experienced six cases of cerebellar hemorrhage after supratentorial aneurysm surgery, and all of the patientswere improved by instituting conservative medical treatment. The possible mechanism for the remote cerebellarhemorrhages seen in our series is probably a multifactorial effect, such as excessive epidural hemovac and CSF drainage,and jugular venous compression due to the operative position. The purpose of this report is to alert neurosurgeonsto the existence of this syndrome and to suggest several ways of minimizing the possibility of their patients developingremote cerebellar hemorrhage.
