摘 要 目的:将CSEP作为评价脊髓型颈椎病术前术后脊髓功能状态的评分标准,对脊髓型颈椎病(CSM)患者
MR I T2相有无高信号与患者预后的相关性进行评估.方法:将56例接受颈椎后路双开门手术的脊髓型颈椎病患者分
为无高信号组及有高信号组,分别于手术前及术后8d行胫后神经,正中神经及尺神经CSEP检查.结果:56例病人中21
例(37. 5 %)手术前MR I显示有异常高信号(ISI).(1)手术前有MR I T2相高信号(ISI)组正中神经,胫后神经及尺神经
CSEP较无MR I T2相高信号(ISI)组潜伏期略长,波幅略小,但t检验两组无显著性差异(P> 0. 05);(2)手术后CSEP
潜伏期及波幅改善值两组t检验亦无显著性差异(P> 0.05).结论:术前有无MR I T2相高信号与患者的预后无明显相
关.有高信号患者同样可有良好预后.

Abstract Objective : To analyze t he correlations between t he increased signal intensity of t he spinal cord on magnetic reso2
nance images andprognosis of cervical compressive myelopat hy by CSEP. Met hods : Fifty2sixpatients wit h cervical spondylotic
myelopat hy were treated by double open2door surgery t hroughposterior approach at Qilu hospital. They included 40 men and 16
women whose mean age was 51. 2(range 35～78). Thepatients were diagnosed to have cervical spondylotic myelopat hy based
on bot h t he neuralgic examination and MR I findings t hat show spinal cord compression. They were divided into twogroups ac2
cording topre2surgery MR images : ISIgroup and no ISIgroup ,t he former was classified into focal ISIgroup and multi2segmen2
tal ISIgroup . Thepreoperative andpost2operative CSEP ofposterior tibial nerve ,ulnar nerve and median nerve were recorded.
Thepost2operative CSEP wasperformed 8 days after surgery. Results : Increased signal intensity was observed in 21patients
(37. 5 %),16patients showed focal ISI and 5 showed multi2segmental.(1)There was no statistically significant difference be2
