The cortical somatosensory evoked potential (SEP) disappeared during corrective spinal surgery in a patient with muscular dystrophy. The patient died 18 hours after surgery. Autopsy revealed an intramedullary hemorrhage 4 mm in diameter in the posterior horn of the cervical spinal cord. Microscopically, hypoxic neurons were seen adjacent to the hemorrhagic area, implying that the lesion was at least 6 hours old. The hemorrhage corresponded to the loss of SEPs and confirms that spinal cord monitoring can detect such lesions.
在一名患有肌肉萎缩症的患者进行脊柱矫正手术期间，皮质体感诱发电位（SEP）消失。患者术后18小时死亡。尸检发现颈髓后角有一个直径4毫米的髓内出血。显微镜下，在出血区域附近可见缺氧神经元，这意味着该病变至少已有6小时。出血与SEP消失相对应，证实脊髓监测可检测到此类病变。
