Intraoperative monitoring (IOM) of the motor pathways is a routine procedure for ensuring integrity of corticospinal tracts during scoliosis surgery. We have previously demonstrated presence of ipsilateral motor evoked potentials (MEPs) during IOM for scoliosis surgery, but its significance was uncertain. In this case series, we show concurrent ipsilateral and contralateral MEP amplitude changes obtained with cortical stimulation are of value in reducing false positive observations during IOM. The use of this easily recordable MEP is thus advocated as a diagnostic adjunct to contralateral MEPs for scoliosis and spinal surgery.
运动通路的术中监测(IOM)是脊柱侧弯手术中确保皮质脊髓束完整性的常规操作。我们之前已经证实在脊柱侧弯手术的IOM过程中存在同侧运动诱发电位(MEP),但其意义尚不确定。在这个病例系列中,我们表明通过皮质刺激获得的同侧和对侧MEP幅度的同时变化,对于减少IOM期间的假阳性观察结果具有价值。因此,提倡使用这种易于记录的MEP作为脊柱侧弯和脊柱手术中对侧MEP的诊断辅助手段。
