Abstract

：Objective To summarizeour experience with intraoperative neural electrophysiological monitoring during spinalcord surgery. Methods The clinical data of 11 patients undergoing spinal cord surgery withintraoperative neural electrophysioiogical monitoring were retrospectively reviewed, andthe monitoring was performed by recording the motor-evoked potential (MEP), somatosensoryevoked potential (SEP), and evoked electromyography (EMG). Results Subtotal resection ofthe intramedullary cystic lesion was performed in 1 case and partial resection of theintramedullary tumor in another. In 9 cases of tethered spinal cord syndrome, obviousimprovement was obtained in 8 cases, and the other 1 case showed no obvious changes in thesymptoms after the operation. In all the 11 cases, the spinal cord remained intact and itsfunction was totally preserved without damage of the eonus medullaris or the cauda equine.Conclusion Combined monitoring of MEP, SEP, and evoked EMG during spinal cord surgery isuseful for protecting the spinal cord and the nerves roots, and may enhance the detectionof the tethered tissue and ensure better safety of operations. Key words: Spinal cord; Neural electrophysiological monitoring; Tethered spinalcord syndrome
