神经导航在幕上肿瘤锁孔手术的应用(附35例报告)

Application of neuronavigation in supratentorial tumour keyhole surgery: report of 35 cases

目的评价神经导航在幕上肿瘤锁孔手术的应用价值。方法分析应用神经导航系统进行幕上肿瘤锁孔手术35例病人的临床资料。结果肿瘤及周围解剖结构定位准确,平均注册误差(2.8 ±0.4)mm。肿瘤全切率85.7%,手术时间和住院日较常规开颅手术缩短。结论①神经导航定位精确,有助于手术计划的精确实施。②导航颅内肿瘤锁孔手术有助于达到微侵袭效果,提高肿瘤全切除率。③摸索了一套减少靶点漂移的经验。

Objective To assess the clinical value of neuronavigation in supratentorial tumor keyhole surgery. Methods The neuronavigation system was applied for keyhole surgery in 35 cases with supratentorial tumor, and the clinical data were reported. Results The tumours and the surrounding structures were located accurately with mean registration error of (2.8±0.4) mm. Total tumour removal was achieved in 30 cases (85.7%). The duration for operating and staying in hospital were found shorter in cases under neuronavigation keyhole surgery than those under conventional surgery. Conclusion The neuronavigation system is accurate in real-time orientation of keyhole surgery, and increases the radical rate for supratentorial tumor by keyhole surgery with favourable micro-invasive outcomes. The methods of reducing brain shift are presented.
