Currently we report a case with severe spine deformity in which intraoperative neurological monitoring (IOM) loss after interrupting T8 nerve root finally led to spinal cord injury during PVCR surgery.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Case presentation<\/jats:title>\n<jats:p>The patient was a 14-year-old female with severe congenital kyphoscoliosis (CKS) without preoperative neurologic deficits. The IOM events (MEP loss and SSEP latency prolong) were showed when T8 nerve root at concave side was interrupted. And then we reduce the scope of osteotomy to control bleeding, raised blood pressure (MAP, 65\u201380) to increase blood supply for spinal cord, placed the bilateral rod to stabilized the spinal cord, used the methylprednisolone, explored the presence or absence of spinal cord compression, and prepared to change the surgical plan from PVCR to PSO. After that the IOM signals partial recovered from the lowest point. Postoperatively the patients showed transient motor function deficits of left lower limbs weak without somatosensory deficits, and come back to preoperative status 6\u2009months later.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Interrupting the thoracic spine nerve root is danger to trigger the spinal cord injury during PVCR procedure of severe CKS.
