神经导航引导下的显微手术治疗颅内病灶

Application of Neuronavigation System to Microsurgical Treatment for Intracranial Lesions

目的 :探讨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 2 8例颅内病灶患者进行 3mm层厚的CT或磁共振 (MR)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 2 3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。

Objective: To operate with minimal invasion is what neurosurgeons have been seeking for long time. Neuronavigation system aided by computer is one of the powerful tools that help to finish operation more precisely. The application of neuronavigation system to the treatment of intracranial lesions was to be evaluated. Methods: Twenty eight cases with intracranial lesions were scanned (CT or MRI) with slice thickness of 3 mm preoperatively. Operation planning,skin incision design,identification of lesions and surrounding critical structures were all done under the direction of navigation station. Results: All cases were targeted precisely. Among them,total resections were achieved in 23 cases,subtotal resection in 2 cases,and part resection in 3 cases. There was no neurological deficit upon discharge. Conclusion: Microsurgery aided by neuronavigation system can be performed precisely with maximal preservation of neurological function.
