33例电磁导航在颅脑手术中的应用分析

The application of electro-magnetic navigation in craniotomies

目的探讨COMPASS Cygnus电磁导航在颅脑手术中的应用价值。方法回顾性分析2009年收治的33例电磁导航辅助颅脑外科手术治疗患者的临床资料。结果电磁导航系统病变定位成功率100,图像匹配误差0.88~3.10mm,平均1.54mm。术后无明显神经功能损害。系统安全性、稳定性、兼容性高。结论电磁导航系统可提高手术精度,缩短手术时间,减少手术并发症,有望成为新一代导航手段。

Objective To investigate the value of COMPASS Cygnus electro-magnetic navigation in neurosurgical operations.Methods A retrospective review of 33 patients who were operated under the guidance of COMPASS Cygnus electro-magnetic navigation system in 2009 were conducted.Results All the intracranial lesions were accurately located.The estimated error was 0.88~3.10mm,and the mean fiducial error was 1.54mm.No postoperative neurological complication and no operative death were observed.The navigation system was safe,stable,convenient and withoutsignal blockage.Conclusion Electro-magnetic navigation system could assist lesion location accurately and reduce operation time and decrease operation complications.It can be considered to be a new generation of operation guidance system.
