摘要
背景与目的:神经导航外科是微侵袭神经外科的重要组成部分,本研究评价神经导航在颅内星形细胞肿瘤显微手术中的应用价值。方法:回顾性分析哈尔滨医科大学肿瘤医院神经外科于2004年9月至2007年4月应用神经导航系引导进行颅内星形细胞肿瘤切除术的54例病例资料。结果:用神经导航系统进行星形细胞肿瘤及其周围解剖结构定位准确,平均注册误差(1.42±0.46)mm。术后近期复查,CT或MRI证实肿瘤全切36例(78%),次全切除10例,大部切除8例。所有肿瘤全切患者术后增强CT或MRI检查未发现肿瘤残留病灶。结论:神经导航定位精确,有助于手术计划的精确实施。实时导航颅内星形细胞肿瘤显微手术,有助于达到微侵袭效果和提高肿瘤全切除率。
BACKGROUND ＆ OBJECTIVE：To assess the clinical value of neuronavigation in the resection of intracranial astrocytomas. METHODS： From September 2004to April 2007, 54 patients with intracranial astroeytomas were operated with the assistance ofneuronavigation system. The diameter of tumors ranged from 2.8cm to 7.0 cm, with a mean diameter of 6.5cm. The operations were guided by neuronavigation system. RESULTS： The tumors and the surrounding structures were located accurately with mean registration error 1.42±0.46mm. Among 54 cases, total removal was achieved in 36 cases, subtotal removal in 10 cases and partial removal in 8 cases. CONCLUSION： The neuronavigation system is accurate in real-time orientation of intracranial astrocytomas microsurgery. It improve the resection of intracranial astrocytomas with micro-invasion.
