Application of ASA-610V neuronavigation system in minimally invasive neurosurgery

Objective The application of ASA-610V neuronavigation system in minimally invasive neurosurgery was studied. Methods The micro-neurosurgery was performed in 89 patients with ASA-610V neuronavigation system. Their disorders included intracranial tumor (n=70), inflammatory lesion (n = 12) and cerebral arteriovenous malformation (n=7). Of these lesions, 10 patients with tumor in motor function area were resected by fMR1-guided neuronavigation. Results The mean registration error of the system was about 2.5 mm. The total removal rate of these lesions was 66.29% (59/89), subtotal removal rate was 20.22% (18/89) and partial removal rate was 13.48% (12/89). The prognosis in 80 patients was good, and minimal postoperative complications occurred in 9 cases. Postoperation in patients with total removal of tumor in motor area of cerebrum, the exacerbation of dysfunction in nervous system was not found. Conclusion ASA-610V neuronavigation system can provide an accurate localization in neurosurgery, especially for the lesions in base of skull and motor functionarea, and it is helpful in increasing removal rate and decreasing the surgical complication.
