| ABSTRACT |
|
Four cases of intracerebral hemorrhage remote from the site of initial supratentorial craniotomy are presented.
Traumatic cases are excluded in this report and all cases developed after uneventful elective craniotomy. Two patients had ruptured aneurysm and the other two had giant supratentorial tumors, one craniophayrngioma and one ependymoma. All patients were operated on supine position and no patient had preoperative hypertension. Two had hematoma in the sucortical white matter, one in the cerebellar hemisphere and the other one showed hematoma both in the cerebellar hemisphere and the supratentorial subcortical area. The size of hematoma ranged from 8-20cc in volume. No definite cause could be found except one in which the blood pressure was transiently elevated during induction of anesthesia. A possible cause might be the sudden changes of blood pressure during induction and recovery from anesthesia, overdrainage of CSF, continuous CSF drainage and sudden changes in intracranial dynamics by removal of a huge intracranial mass. One patient with intracerebellar hemorrhage needed emergency suboccipital craniectomy for removal of the hematoma. One patient shows no improvement due to aspiration pneumonia and subsequent lung abscess.
Although rare, these conditions may occur after any craniotomy and surgeons should always be alert to the possibilities of such comlication, especially when intracranial pressure(ICP) was elevated. |
