神经导航辅助切除邻近重要功能区神经胶质瘤

Neuronavigation-assisted resection of gliomas near eloquent regions

目的 介绍神经导航系统在切除邻近重要功能区神经胶质瘤 (简称胶质瘤 )手术中的初步应用体会。 方法 2 0 0 0年 6月～ 2 0 0 1年 2月 ,应用BrainLAB公司VectorVision2导航系统辅助切除邻近重要功能区胶质瘤 11例 ,并对神经导航用于胶质瘤手术的优越性、精确性以及注意事项进行分析。 结果 本组病例中 ,平均注册误差为 (1 5± 0 7)mm ,术后近期复查CT或MRI证实肿瘤全切除率为 81 8%,患者临床症状均得到改善 ,肢体活动等重要神经功能未受明显影响 ,无手术并发症。 结论 神经导航系统对于切除邻近重要功能区胶质瘤具有定位准确、动态示踪、微侵袭、安全可靠等特点 ,有助于提高胶质瘤的全切除率及降低手术并发症的发生。

Objective To evaluate the effect of the neuronavigation system in operation of gliomas near eloquent regions. Method The brain LAB VV2 navigation system was used in 11 patients with gliomas near eloquent regions. The value of this system for glioma resection was assessed, and the accuracy and notice for application were discussed. Results The mean registration error was (1.5±0.7)mm in the patients. Total lesion removal was achieved in 9 patients (81.8%). The clinical status of all patients improved, and their functions of motor were not significantly affected. No complications were attributed to the use of this system. Conclusion The neuronavigation system is reliable and accurate in surgical treatment of gliomas near eloquent regions. It increases the fraction of radical in glioma resection without injury to the critical functions.
