Abstract

A 43 year old man underwent spinal cord surgery for removal of filum terminale lipoma. Intraoperative somatosensory evoked potentials (SSEP) monitoring showed a transient loss of response on simultaneous bilateral posterior tibial nerve (PTN) stimulation that recovered within 20 minutes. The patients exhibited paralysis and abnormal proprioceptive perception in the right leg postoperatively, when SSEP recordings revealed abnormal response to right PTN and normal response to bilateral PTN stimulation. In order to avoid false negative intraoperative responses, stimulation of each leg independently in an alternative fashion is recommended.

摘要

一名43岁男性因终丝脂肪瘤切除接受脊髓手术。术中体感诱发电位（SSEP）监测显示，在同时双侧刺激胫后神经（PTN）时出现短暂反应丧失，20分钟内恢复。术后患者右腿出现瘫痪和异常本体感觉，此时SSEP记录显示对右侧PTN刺激反应异常，对双侧PTN刺激反应正常。为避免术中出现假阴性反应，建议交替独立刺激每条腿。
