title: Stereotactic burr hole aspiration surgery for spontaneous hypertensive cerebellar hemorrhage.
abstract: OBJECTIVE
  Patients with severe spontaneous cerebellar hemorrhage typically undergo treatment with suboccipital craniectomy and hematoma evacuation. However, this is a stressful procedure for patients due to the long operating time and operation-induced tissue damage. In addition, the durotomy can result in pseudomeningocele. We investigated the efficacy of stereotactic or navigation-guided burr hole aspiration surgery as a treatment for spontaneous hypertensive cerebellar hemorrhage (SHCH).
  
  
  METHODS
  Between January 2002 and December 2011, 26 patients with SHCH underwent surgery using the stereotactic or navigation-guided burr hole aspiration and catheter insertion technique in our institution.
  
  
  RESULTS
  Mean hematoma volume was 21.8 ± 5.8 cc at admission and 13.1 ± 5.4 cc immediately following surgery. Preoperative Glasgow Coma Scale (GCS) score was 12.5 ± 1.3 and postoperative GCS score was 13.1 ± 1.2. Seven days after surgery, the mean hematoma volume was 4.3 ± 5.6 cc, and there was no occurrence of surgery-related complications during the six-month follow-up period. The mean operation time for catheter insertion was 43.1 ± 8.9 min, and a mean 31.3 ± 6.0 min was also added for extra-ventricular drainage. The mean Glasgow Outcome Scale (GOS) score after six months was 4.6 ± 1.0.
  
  
  CONCLUSIONS
  Stereotactic burr hole aspiration surgery for treatment of SHCH is less time-consuming and invasive than other interventions, and resulted in no surgery-related complications. Therefore, we suggest that this surgical method could be a safe and effective treatment option for selected patients with SHCH.
