Haematoma evacuation in cerebellar intracerebral haemorrhage: systematic review.

Controlled studies on the effect of neurosurgical treatment in patients with spontaneous cerebellar ICH are lacking, and the risk of bias in published series is high. Due to substantial differences in patient characteristics between conservatively and surgically treated patients, and high variability in treatment indications, a meaningful comparison in outcomes could not be made. There is no good published evidence to support treatment recommendations and controlled, preferably randomised studies are warranted in order to formulate evidence-based treatment guidelines for patients with cerebellar ICH.
