摘要 目的探讨皮层体感诱发电位(CSEP)联合经颅电刺激运动诱发电位(TES-MEP)在椎管内占位手术中的应用价值。方法 2009年7月至2011年1月,在52例颈胸椎管内占位手术中实施CSEP联合TES-MEP监护。椎管内肿瘤患者46例,椎管内血肿患者6例。患者均采用后方手术入路。均采用全静脉麻醉。结果 9例术中诱发电位阳性的病例中,除2例不明原因的假阳性外,7例与手术操作直接相关。4例患者术中CSEP明显改善,2例患者术中CSEP好转的同时伴部分肌肉TES-MEP的出现。1例患者术中无电位变化,术后3h出现双下肢瘫痪,MRI证实为术后血肿引起。CSEP的灵敏度67.0%,特异度95.6%,约登指数0.66。术中TES-MEP的灵敏度83.3%,特异度97.6%,约登指数0.81。联合监护的灵敏度100%,特异度93.0%,约登指数0.93。结论 TES-MEP可补充CSEP对脊髓运动功能监护的不足,极大提高手术的安全性,并在一定程度上预测患者的预后;CSEP联合TES-MEP监护可指导围手术期脊髓再损伤的诊断。
