We describe a technique for placement of a cervical spinal cord electrode under general anesthesia using the contacts as cortical evoked potential stimulating electrodes.
A 37-year-old man required revision of the percutaneous lead of a spinal cord stimulator system placed for right upper extremity pain. A Resume-TL laminotomy lead was inserted at the C5-6 interspace in the prone position under general anesthesia. The contacts were functionally over the right dorsal column by evoked potential recording, despite the apparent midline position of the lead.
Postoperatively, the patient had excellent coverage and pain relief at the right shoulder and extremity. There was no stimulation perceived on the left side of the body.
This technique allows for intraoperative testing under general anesthesia in laminotomy lead placement to localize the optimal position of the lead.
我们描述了一种在全身麻醉下使用接触作为皮质诱发电位刺激电极来放置颈椎脊髓电极的技术。
一名 37 岁男性因右上臂疼痛需要对脊髓刺激器系统的经皮引线进行修改。在全身麻醉下，患者取俯卧位，行 Resume-TL 椎板切开术导引线插入 C5-6 椎间。通过诱发电位记录，尽管导引线明显位于中线位置，但接触点位于右侧背柱功能区。
术后，患者右肩部和上肢的覆盖范围和疼痛缓解效果极佳。身体左侧没有感觉到刺激。
这种技术允许在椎板切开术导引线放置过程中进行全身麻醉下的术中测试，以定位导引线的最佳位置。
