RÉSUMÉ
Objective:To explore the application value of microsurgical tethered cord release in children with tethered cord syndrome under perioperative electro-neurophysiology monitoring.Methods:Ninety-six patients with tethered cord syndrome accepted tethered cord release in our hospital from January 2015 to December 2019 were chosen in our study; perioperative electro-neurophysiology monitoring was performed to evaluate whether there was neurological impairment. The surgical results, neuroelectrophysiological monitoring results, and follow-up results were retrospectively analyzed.Results:In these 96 patients, symptoms disappeared in 45 patients, improved in 34, not improved in 10, worsened in 3, and tethered again in 4 patients, with a total effective rate of 82.6%. No death was noted. Preoperative neuroelectrophysiological monitoring showed abnormal sensory and motor functions of lower limbs in 40 patients, and postoperative monitoring showed abnormal sensory and motor functions of lower limbs in 6 patients. Follow up was performed for an average of 13 months; symptoms improved in 79 patients, stabilized in 10 patients, and aggravated in 7 patients.Conclusion:In children with tethered cord syndrome, tethered cord release should be performed as soon as possible regardless of early neurological injury; perioperative electro-neurophysiology monitoring can protect spinal cord function, prevent nerve function injury, improve the surgical safety and improve the prognosis of these children.
