Preliminary study of StealthStation neuronavigation in the operation of intracranial lesions / 解放军医学杂志

ABSTRACT

Objective To evaluate the value of the StealthStation neuronavigation in the operation of intracranial lesions. Methods 22 patients with different intracranial lesions, including 14 cases of glioma, 2 cases of meningioma,4 cases of cavernous angioma,1 case of lymphoma and 1 case of metastatic cancer, were operated on with the aid of StealthStation neuronavigational system. The neuronavigational accuracy and surgical effect were analysed. Results All intracranial lesions were found accurately with StealthStation neuronavigational system, the predicted accuracy (PA) value was 2.53?0.73mm, accuracy sphere of intracranial lesions in the neuronavigational system was within 2mm in all patients. 13 cases out of 14 gliomas were totally removed under microscope, in 1 case removal was subtotal. In 2 patients, neurological symptoms became worse immediately after the operation but improved within 3 months after the operation. The other 12 patients recovered very well. In another 8 cases total removal under microscopy was successful, but one lymphoma patient showed exacerbation of neurological symptoms immediately after operation, but improved within 1 week after operation. The other 7 cases recovered very well. Conclusion The StealthStation neuronavigational system is reliable and accurate in neurosurgical operation, thus it is helpful to facilitate total resection of intracranial lesions with less operative complications.
