摘要
目的:探讨马尾综合征(CES)的神经电生理特征。方法:收集2019年1月至2020年12月于驻马店市第一人民医院经临床确诊为CES的15例患者的临床资料,对神经电生理结果进行回顾性分析。结果:本组资料无一例运动传导速度、感觉传导速度减慢,腓肠、隐神经无一例感觉神经动作电位异常。F波、H反射、神经传导阳性率低于针极肌电图阳性率;针极肌电图阳性率高达100%。外伤起病者位置偏高(第2腰神经根),腰椎间盘突出症起病者位置偏低(第5腰神经根)。CES可双侧对称或不对称,与发病机制相关,但二者间统计数据比较差异未见统计学意义(P>0.05)。盆底肌在第3~4骶神经根功能检查中应用简单、便捷,可有效保护患者隐私。结论:神经电生理检查判断CES简单,具有良好的一致性和真实性,对神经根损伤的定位、定性诊断意义重大。
Objective To investigate the electrophysiological characteristics of cauda equina syndrome(CES).Methods The clinical data of 15 patients with CES diagnosed in the First People’s Hospital of Zhumadian from January 2019 to December 2020 were collected,and the results of neuroelectrophysiology were analyzed retrospectively.Results There was no decrease in motor conduction velocity and sensory conduction velocity,and no abnormality of sensory nerve active potential in sural nerve and saphenous nerve.The positive rate of F wave,H reflex,and nerve conduction was lower than the positive rate of needle electromyography.The positive rate of needle electromyography was 100%.The region of onset was higher in patients with trauma(the second lumbus nerve root)and lower in patients with lumbar disc herniation(the fifth lumbus nerve root).CES could be bilateral symmetric or asymmetric,which was related to the pathogenesis,but there was no significant difference in statistical data(P>0.05).The pelvic floor muscle group in the third to fourth sacral nerve root function examination was simple and convenient,which can effectively protect the privacy of patients.Conclusions The nerve electrophysiological method is simple,consistent and authentic,which is of great significance for the localization and qualitative diagnosis of nerve root injury.
