Herniated lumbar disc surgery in triathlon athletes with intraoperative neurophysiologic monitoring Cirurgia de hérnia de disco lombar em atleta de triathlon com monitoração neurofisiológica intraoperatória

ABSTRACT Intraoperative neurophysiologic monitoring was performed in a patient by somatosensory evoked potential, motor evoked potential and free-running electromyography with intraoperative stimulation. It was verified that after decompression, there was an increase in the amplitude of motor evoked potential responses, showing an immediate improvement of the treated levels. Intraoperative neurophysiologic monitoring for surgical lumbar disc herniation in an athlete allowed a dynamic neurophysiological diagnosis, differentiation of the involvement of compression at the central or foraminal levels, and clinical awareness of the iatrogenic damage, thereby increasing safety. Keywords: Intervertebral disk displacement/surgery; Athletes; Monitoring, intraoperative; Decompression, surgical; Case reports RESUMO Foi realizada em um paciente a monitorizacao intraoperatoria neurofisologica com potencial somatossensitivo, motor e eletroneuromiografia continua com estimulacao intraoperatoria. Depois da descompressao, ocorreu aumento da amplitude de resposta do potencial evocado motor, mostrando imediata melhora dos niveis tratados. A monitorizacao neurofisiologica intraoperatoria para hernia de disco lombar em um atleta permitiu um diagnostico neurofisiologico dinâmico, diferenciacao da compressao central ou foraminal e diagnosticar qualquer alteracao iatrogenica aumentando a seguranca.
