title: Endoscopic hematoma evacuation for hypertensive cerebellar hemorrhage.
abstract: OBJECTIVE
  The management of spontaneous cerebral hemorrhage remains controversial, particularly the surgical indications. Endoscopic surgery was evaluated for the treatment of spontaneous cerebellar hemorrhage.
  
  
  METHODS
  The records of 69 patients with hypertensive cerebral hemorrhage were retrospectively reviewed. Patients treated by endoscopic surgery (n = 10) were compared with patients treated by conventional surgical hematoma evacuation (n = 10) under the same surgical indications.
  
  
  RESULTS
  The surgical procedure time, duration of ventricular drainage, extent of hematoma evacuation, necessity for cerebrospinal fluid (CSF) shunt, surgical complications, and outcome at discharge and at 3 months after onset were compared. The extent of hematoma evacuation was greater in the endoscopic group (95.2 %) than in the craniectomy group (90.6 %) but without significant difference. The endoscopic technique (64.5 min) took significantly less time than the craniectomy method (230.6 min, p < 0.0001). The period of ventricular drainage was significantly shorter in the endoscopic group (2.6 days) compared to the craniectomy group (12.3 days, p < 0.01). CSF shunt surgery was required in no patient in the endoscopic group compared to three in the craniectomy group.
  
  
  CONCLUSIONS
  Endoscopic hematoma evacuation is a rapid, effective, and safe technique for the removal of hypertensive cerebellar hemorrhage. Reduction of the mass effect can be accomplished with low risk of recurrent hemorrhage. Release of obstructive hydrocephalus in the early stage may improve the patient's outcome and decrease the requirement for permanent shunt emplacement.
