Long-term outcome and prognostic factors after spontaneous cerebellar hemorrhage.

Cerebellar hemorrhage is the least common type of intracranial hemorrhage (ICH) encountered in clinical practice, and clinical data concerning the long-term outcomes are limited. This study aimed to investigate the long-term outcomes following spontaneous cerebellar hemorrhage in a cohort of Chinese patients. This single-center observational study was carried out between 1996 and 2010 and included 72 consecutive Chinese patients with a first spontaneous cerebellar hemorrhage. Of 440 patients with primary ICH, 72 (16.4%) had primary cerebellar hemorrhage. The mean age was 67.5 ± 12.3 years and patients were predominantly male (54%). The 30-day mortality was 16.7% with Glasgow coma scale ≤ 8 as the only predictor. At 6 months, 56.7% of patients who survived the first 30 days had a persistently poor functional status with modified Rankin scale score >2. After a mean follow-up of 4.7 years, 3.3% of patients had recurrent ICH, a recurrence rate of 7.3 per 1,000 patient-years. Ischemic stroke occurred in 12% of patients, an incidence of 25.5 per 1,000 patient-years. This study provided data on the long-term outcome of post-cerebellar hemorrhage in Chinese patients.
