神经导航辅助下的微创显微手术处理颅内病变

Neuronavigation System in the Microsurgical Treatment of Intracranial Lesions

微创手术是神经外科手术的发展趋势和基本要求,计算机神经导航系统使手术更精确。本文探讨了神经导航在颅内病变微创显微手术中的应用价值,以最小的手术创伤来达到最好的手术疗效。方法:对27例颅内病灶患者进行3mm层厚的CT或MRI扫描,利用导航工作站进行术前计划、切口设计、术中指示病灶部位及重要颅内结构。结果:所有病灶定位准确,全切22例,次全切除2例,大部切除3例。术后神经功能保留良好。结论:神经导航辅助下的微创显微神经外科手术可以达到准确定位及切除病灶,减少功能损害的目的。

BACKGROUND & OBJECTIVE: Minimizing damage to normal nervous tissue while maintaining maximal removal of intracranial lesion is what neurosurgeons been seeking for a long time. The concept is now commonly referred to as minimally invasive neurosurgery. Computerized neuronavigation system is one of the most powerful tools that help to achieve this goal. In this paper, the application of neuronavigation system to the treatment of intracranial lesions was evaluated. METHODS: Twenty-seven cases with intracranial lesions were scanned by CT or MRI with slice thick-ness of 3 mm preoperatively. Planning of the operation approach, design of skin incision, localization of lesions and surround-ing critical structures were all done under the guidance of neuronavigation station. RESULTS: The localization of the le-sions was precise in all the cases. Among them, total resection was achieved in 22 cases, subtotal resection in 2 cases,and partial resection in 3 cases. There is no neurological deficit upon discharge. CONCLUSION: Neuronavigation sys-tem can improve the precision in microsurgery and the preservation of neurological function.
