title: Neuronavigation for the resection of cavernous angiomas.
abstract: OBJECTIVE
  To introduce the use of the StealthStation neuronavigator combined with preoperative computerized tomography (CT) in resection of intracranial cavernous angiomas (CAs).
  
  
  METHODS
  The StealthStation neuronavigator was used to provide a realtime correlation of the operating field and the computerized images in 6 patients with CAs. All patients suffered from epileptic seizures. Four patients underwent keyhole surgery and 2 underwent small skin-flap craniotomy. The mean follow-up was 4.5 months.
  
  
  RESULTS
  With the guidance of neuronavigator, lesionectomy associated with removal of hemosiderin deposition, gliosis and calcification was performed precisely. The mean fiducial error was from 1.65 mm to 4.53 mm, the predicted accuracy at 10 cm was between 1.82 mm and 3.28 mm, and the sustained accuracy ranged from 0.50 mm to 3.45 mm.
  
  
  CONCLUSIONS
  The StealthStation neuronavigator is reliable and accurate in the resection of CAs.
