Cerebellar haemorrhage following supratentorial craniotomy.
Distant cerebellar haemorrhage is a rare complication occurring in approximately 0.3-0.6% of all supratentorial craniotomy. A Medline and Pubmed search revealed only 98 cases in the English literature. We report three cases from our institution. An overall review of these 101 cases demonstrated that this complication commonly presented early in the postoperative course as decreased level of consciousness following aneurysm repair surgery or lobectomy for epilepsy. Asymptomatic presentation due to small haemorrhage was not uncommon. A transtentorial pressure gradient set up by excessive CSF loss is generally held responsible for disrupting the cerebellar venous blood flow and consequently leading to venous haemorrhage. Perioperative hypertension may also play a role. The outcome of patients who survived the complications was generally good, though not infrequently fatality resulted from the mass effect of extensive cerebellar haemorrhage demanded vigilance in its management.
