神经导航显微外科在脑肿瘤手术中的应用

目的 探讨在神经导航下脑肿瘤及其周围结构定位的准确性和显微手术的治疗效果。方法 应用Stealth Station和Vector Vision神经导航系统,以显微手术切除65例脑肿瘤,分析导航定位的准确性与手术治疗效果的关系。结果 65个脑肿瘤,在满足神经导航注准确性和术中导航持续准确性的前提下,全切除63个（97.0%）、次全切除2个（3.0%）。出院时患者症状明显改善56例（86.2%）,无明显变化9例（13.8%）,无病情恶化及死亡。结论 使用神经导航系统,在术前可制定详细的脑肿瘤手术计划,术中可辅助术者追踪瘤体、准确定位,有 地切除肿瘤并降低手术并发症。

Neuronavigator-guided microsurgery for resection of brain tumors

OBJECTIVE: To study locating accuracy for the brain tumors and their peri-structures by the neuronavigator and elucidate the microsurgical effects. METHODS: 65 patients with intracranial tumors were microsurgically treated by the application of Stealth Station and Vector Vision system. The treatment effects were summarized and the neuronavigational accuracy was discussed. RESULTS: After mean fiducial error (MFE) and sustained accuracy (SA) were satisfied. Total tumor removal was achieved in 63 cases (97.0%), subtotal removal in 2 cases (3.0%). The neurological functions were improved in 56 cases (86.2%), unchanged obviously in 9 cases (13.8%). No case deteriorated and died in the group. CONCLUSIONS: Navigation systems are reliable and accurate in making microneurosurgical plans for brain tumors. And they can provide tracing of the tumor in the operation and guide the operator's manipulation. The techniques, which help total removal of the tumors and reduce the postoperative complications, are very useful in guarantee operation effects.
