Indication to surgical management of cerebellar hemorrhage.

Few reports have compared patients operated for cerebellar infarcts with those operated for cerebellar hemorrhage. Considering our previous paper about patients with massive cerebellar infarcts, we report on our surgical experience with five patients with cerebellar hemorrhage. The indication for operation was decreased consciousness with signs of brainstem compression. In all patients hydrocephalus was absent or mild, as opposed to patients with cerebellar infarcts. Suboccipital craniotomy with hematoma evacuation was therefore the surgical procedure of choice. The outcome was worse than in patients with cerebellar infarcts. We conclude that depressed mental state in cerebellar hemorrhage is mainly due to pressure of the cerebellum on the activating reticular system of the brainstem. The surgical approach to patients with bleeding in the cerebellum differ somewhat from that of patients with cerebellar infarcts in timing and kind of first choice procedure.
