[Neuronavigation for the resection of intracranial cavernous angiomas].
OBJECTIVE
To evaluate the use of the Stealth Station neuronavigator in conjunction with preoperative computerized tomography (CT) in the resection of intracranial cavernous angiomas (CAs).


METHODS
The Stealth Station neuronavigator was used to provide real-time correlation of the operating field and computerized images in 6 patients with CAs. All of them suffered from epileptic seizures.


RESULTS
Neuronavigation-guided lesionectomy with removal of hemosiderin deposition, gliosis and calcification in all cases was performed precisely. Mean fiducial error, predicted accuracy at 10 cm, and sustained accuracy ranged from 1.65 to 4.53 mm, 1.82 to 3.28 mm, and 0.50 to 3.45 mm, respectively.


CONCLUSIONS
The Stealth Station neuronavigator is reliable and accurate in the resection of CAs.
