New neuronavigation in microsurgery for intracranial tumors

Objective To explore the application of new neuronavigation in microsurgery for intracranial tumors. Methods Thirty-six patients with intracranial tumors, admitted to our hospital from November 2016 to April 2017, were treated with brain LAB KICK neuronavigational system-assisted micro-neurosurgery. Preoperative MRI or CT thin-layer scanning were performed, and the images were input to the Brain LAB Vector Vision neural system for three-dimensional reconstruction. The tumors and the important structures were marked. Intraoperative guidance in the neuronavigation system was performed to find the important nerves, vascular and bone signs and other structures. The clinical data and therapeutic effect of these patients were retrospectively analyzed. Results All the 36 patients were successfully guided by neuronavigation to reach the tumor sites, with the registration error of 0.10-0.25 mm. Total resection was achieved in 31 patients, subtotal resection in 3, and most resection in 2. Symptoms improved significantly in 34 patients after the surgery. No surgical complications caused by neuronavigation errors were found, and no asymptomatic deterioration or death were noted. Conclusion Brain LAB neuronavigation system in neurosurgery is accurate and safe, enjoying high total resection rate and minimized operation complications.
