ABSTRACT

Resumen: Introducción: La neuropatía ciática es una entidad infrecuente y de difícil diagnóstico en Pediatría. Su evolución a largo plazo no ha sido claramente definida. Objetivo: Analizar la presentación clínica y evolución de un grupo de niños con neuropatía ciática. Pacientes y Método: Análisis retrospectivo de las características clínicas de pacientes pediátricos con neuropatía ciática atendidos en 2 hospitales de Santiago, entre 2014-2018. Se evaluó examen motor, trofismo muscular, reflejos osteotendíneos, marcha, sensibilidad y dolor. Se estudió neuroconducción de nervio ciático, electromiografía (EMG) y en 3 pacientes, Resonancia Magnética (RM). Resultados: Se incluyeron 6 pacientes, edad promedio 11,8 años. Hubo 2 causas traumáticas, 2 compresivas, 1 vascular y 1 tumoral. Los 6 pa cientes debutaron con pie caído e hiporreflexia/arreflexia aquiliana; 5 pacientes presentaron dolor neuropático severo. La EMG mostró en todos los casos compromiso en nervios y musculatura de pendientes del nervio ciático. En 2 casos se realizó RM de cintura pélvica y extremidades inferiores, mostrando compromiso muscular selectivo en pierna en territorio ciático. En 1 caso, se realizó RM de plexo lumbosacro, y luego estudio histológico, que concluyeron un tumor neural benigno. En los 3 pacientes que tuvieron seguimiento mayor a un año, se observaron secuelas motoras, con marcha alterada. Conclusión: La neuropatía ciática en este grupo fue secundaria a diversas etiologías, predominando las traumático-compresivas. En los 3 casos que tuvieron seguimiento a largo plazo se observaron secuelas motoras significativas. En la mayoría la lesión se asoció a causas prevenibles como accidentes y posicionamiento en niños con compromiso de conciencia, lo que resulta fundamental en la prevención de una patología con alto grado de secuelas.


Abstract: Introduction: Sciatic neuropathy is rare and difficult to diagnose in pediatrics, and its long-term course has not been completely understood. Objective: To analyze the clinical presentation and evolution of a group of pediatric patients with sciatic neuropathy. Patients and Method: Retrospective anal ysis of the clinical characteristics of pediatric patients with sciatic neuropathy treated in two hospitals of Santiago between 2014 and 2018. Locomotor examination, muscle trophism, deep tendon reflexes, gait, sensation, and pain were assessed. Sciatic nerve conduction study and electromyography (EMG) were performed, and magnetic resonance imaging (MRI) in three patients. Results: Six patients were included with an average age of 11.8 years. The etiologies were traumatic (N = 2), by compression (N = 2), vascular (N = 1), and tumor (N = 1). All of the 6 patients presented foot drop and Achilles tendon hyporeflexia/areflexia, and 5 patients presented severe neuropathic pain. The EMG showed involvement of the sciatic nerve rami and dependent muscles. In two patients, a pelvic girdle and lower limbs MRI was performed, showing selective muscle involvement in sciatic territory. One patient underwent a lumbosacral plexus MRI, and subsequently histological study showing a benign neural tumor. Out of the three patients who were followed-up longer than one year presented motor sequelae and gait disorder. Conclusion: Sciatic neuropathy in the study group was secondary to different causes, predominantly traumatic and compressive etiologies. The three patients that were ina long-term follow-up presented significant motor sequelae. In most of the cases, neural injury wasassoci- ated with preventable causes, such as accidents and positioning in unconscious children, which is crucial in the prevention of a pathology with a high sequelae degree.
