Abstract:
Objective To study the onset,treatment,prognosis and possible causes of transient quadriplegia shortly after anterior cervical compression and fixation (within four hours postoperatively) in three patients with cervical spondylotic myelopathy who could function well for limbs after anesthesia awakening from the operation. Methods A retrospective study was carried out on medical data of three patients including two males and one females,at age of 41-61 years.Anterior cervical corpectomy,titanium mesh bone fusion and titanic plate fixation were performed under general anesthesia.The decompression segment was C5 in one patient,C6 in one and C5 plus C6/7intervertebral disc in one respectively.Paralysis occurred between 30 minutes and 4 hours postoperatively.Two patients were with complete paralysis and one with incomplete. All the patients received dehydration,neurotrophic drugs and high-dose methylprednisolone therapy immediately after paralysis. Meanwhile,emergent cervical MRI was performed,which showed spinal cord swelling,without obvious spinal cord compression by hematoma.Results The paralysis was alleviated completely in two patients within two hours after early medication without additional surgical compression.The other one patient was recovered incompletely at 24 hours after medicationand then underwent posterior cervical laminoplasty,when tremendous pressure was released from cervical spinal cord.But the spinal function had significant recovery after surgical compression and won complete recovery one week later. Conclusions Besides spinal cord ischemia-reperfusion injury,the transient paralysis after anterior cervical surgery may be associated with cervical spinal cord swelling and limited anterior decompression space.Early diagnosis and early intervention of paralysis may save the spinal cord function and attain a satisfactory prognosis.
