新型神经导航系统在颅内肿瘤手术中的应用

New neuronavigation in microsurgery for intracranial tumors

目的探讨新型神经导航系统在颅内肿瘤切除术中的应用价值。方法北京大学深圳医院神经外科自2016年11月至2017年4月在神经导航系统辅助下完成36例颅内肿瘤切除术，术前患者均行MRI或CT薄层扫描，将图像资料输入Brain LAB KICK神经导航系统中进行三维重建，设计最佳手术入路，并对肿瘤及重要结构作标记，术中在神经导航系统引导下寻找重要神经、血管及骨性标志等结构。本研究回顾性分析患者的临床资料和疗效。结果36例患者术中均在神经导航引导下顺利到达肿瘤部位，注册误差0．10～0．25mm。肿瘤全切31例，次全切3例．大部切除2例。术后34例患者的临床症状明显改善，未发现由于神经导航偏差导致的手术并发症．无症状恶化及死亡病例。结论颅内肿瘤切除术中应用Brain LAB KICK神经导航系统准确、安全．肿瘤全切除率高，最大程度减少了手术并发症。

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 K/CK 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.
