Ventriculostomy for hydrocephalus in cerebellar hemorrhage.

ABSTRACT

In a matter of hours the neurologic status of two hypertensive patients deteriorated to coma. Cranial computed tomography (CT) showed mild to moderate cerebellar hemorrhage and secondary hydrocephalus. Ventriculostomy resulted in clinical improvement within 20 minutes and obviated the need for suboccipital craniectomy. Both patients made a very satisfactory recovery. Similar patients have occasionally been observed by others. Ventriculostomy should be considered for patients with cerebellar hemorrhage who have hydrocephalus by CT scan and undergo progressive neurologic deterioration. Because the frequency of improvement and the risk of upward cerebellar herniation following ventriculostomy is unknown, immediate surgical evacuation of the hemorrhage should be anticipated.
