神经导航系统辅助切除邻近重要功能区神经胶质瘤

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。

Resection of glioma close in importantly functional area assisted with neuronavigation system

Objective The effect of neuronavigation system on the resection of glioma close in importantly functional area was studied. Methods During June 2000 to October 2001, the removal of glioma assisted with neuronavigation system were performed in 19 patients with glioma close in importantly functional area (such as frontoposterior region, frontoparietal junction, frontotemporal junction, parietal lobe and basal segment). Results The average error of the system was 1.7 mm (1.2-2.3 mm). Total removal rate of lesions was 84.21% (16/19) and subtotal removal rate was 15.79% (3/19). There were astrocytomas (n=9), anaplastic astrocytomas (n=5), glioblastoma mulitiforme (n=3), oligodendrogliomas (n=1) and astroid oligodendrogliomas (n=1) in these lesions. All patients were well recovered, without any severe complication. Conclusion The neuronavigation system can significantly improve the accuracy, safety and removal levels in the operation of cerebral glioma.
