title: Cerebellar hemorrhage after supratentorial craniotomy--report of three cases.
abstract: We report on three cases of remote cerebellar hemorrhage after supratentorial craniotomy, which had much in common in their computed tomographic, operative, and clinical findings. We speculate that, when the patient is in the supine position, displacement of the cerebellum causes stretching of the superior vermian veins and their tributaries, resulting in tearing of these vessels. Postoperative cerebrospinal fluid overdrainage or massive air reflux into the cranial cavity through the drainage tube may accelerate this process. Meticulous management of the drainage system is necessary to prevent this postoperative complication.
