目的 观察神经导航系统对脑重要功能区附近的神经胶质瘤手术定位的意义。方法2000年6月～2001年10月,在神经导航系统辅助下完成19例邻近脑重要功能区(额后、额顶交界、额颞交界、顶叶和基底节区)神经胶质瘤的切除手术。结果 导航系统对19例患者肿瘤病灶的定位误差为1.2～2.3mm,平均1.7 mm。肿瘤全切除者16例(84.21％),次全切除者3例(15.79％)。术后病理学分类为星形细胞瘤(9例),间变性星形细胞瘤(5例),多形性胶质母细胞瘤(3例),少突胶质细胞瘤(1例),星形-少突混合性胶质细胞瘤(1例)。手术未对患者重要神经功能造成不良影响。结论 借助神经导航系统可明显提高脑神经胶质瘤手术的准确性和安全性,并可显著提高肿瘤的切除程度。
Objective To observe the significance of neuro-navigation system in glioma surgical localization near important brain functional areas. Methods From June 2000 to October 2001, 19 patients with glioma adjacent to the important functional areas of the brain (forehead, frontal border, frontotemporal border, parietal lobe and basal ganglia) were completed with the aid of neuro-navigation system. surgery. Results The localization error of the navigation system in 19 patients with tumor lesions was 1.2 ~ 2.3mm with an average of 1.7mm. Total tumor resection in 16 cases (84.21%), subtotal resection in 3 cases (15.79%). Pathological classification was astrocytoma (n = 9), anaplastic astrocytoma (n = 5), glioblastoma multiforme (n = 3), oligodendroglioma Star - oligodendrocyte mixed glioblastoma (1 case). Surgery did not adversely affect patients with important neurological functions. Conclusion With the help of neuronavigation system, the accuracy and safety of brain glioma surgery can be significantly improved, and the degree of tumor resection can be significantly improved.
