Abstract

Purpose: To show the morphological changes in postoperative lumbar spine. Material and methods: We reviewed 128 Magnetic Resonance Imaging (MRI) studies of lumbar spine. All patients complained of low back pain and had a previous lumbar surgery (1 month to 8 years). All the examinations include axial and sagittal Gadopentate-dimeglumine enhanced T1 weighted imaging. Results: Only 7,8% have the normal appearance of the postoperative lumbar spine. Epidural scar was found in 69% of examinations; of this group, 72% showed radicular involvement, and 28% had no radicular involvement. Recurrent disc herniation was found in 14,8% of exams, using gadopentate-dimeglumine to assist the differentiation from epidural fibrosis; infections like spondylodiscitis and abscess in 12,5%. Other findings included arachnoiditis, pseudomeningoceles and seromas. Conclusions: MRI is a useful method to study the postoperative lumbar spine, specially when enhanced with gadopentate-dimeglumine. Enhanced images can differentiate two of the major complication like epidural fibrosis, and recurrent disc herniation. Spondylodiscitis are important and frequent too. Although the findings of complications in our series in the postoperative lumbar spine represent 92,18 %, these not always explain the symptomatology. Therefore, the interrelation is important with the surgeon to determine which abnormalities are clinically significant. (authors) [Spanish] Objetivo: Mostrar los  More>>

(authors) [Spanish] Objetivo: Mostrar los hallazgos evidenciados en Resonancia Magnetica (RM) en pacientes operados de columna lumbar. Material y metodos: Se evaluaron retrospectivamente 128 estudios de RM de columna lumbar. Todos los pacientes consultaron por dolor lumbar y tenian antecedentes quirurgicos de un tiempo de evolucion que variaba entre 1 mes y 8 anos. En todos los casos el protocolo de estudio incluyo secuencias axiales y sagitales T1 con gadolinio, ademas del protocolo habitual. Resultados: Solo el 7,8 % de los estudios mostro los hallazgos postoperatorios habituales (cambios anatomicos y posquirurgicos sin complicaciones). La complicacion mas frecuente (69%) fue la presencia de tejido fibroso epidural en el nivel intervertebral operado. De este grupo, el 72 % de los pacientes tenia compromiso radicular y el 28 % restante no presentaba compromiso de las raices nerviosas. La recidiva discal se observo en un 14,8 % de los casos, siendo diferenciada de la fibrosis epidural en las secuencias contrastadas. Las infecciones (discitis y colecciones) se encontraron en el 12,5 % de los pacientes. Otros hallazgos menos frecuentes fueron seromas, seudomeningoceles y aracnoiditis. Conclusion: La RM es el metodo de eleccion para el estudio de la columna lumbar operada, especialmente cuando se utilizan secuencias con contraste. Estas permiten distinguir entre la fibrosis epidural y la recidiva discal, las dos complicaciones mas frecuentes, sin olvidar el lugar que ocupan las infecciones. Si bien los hallazgos imagenologicos de complicaciones en la columna operada en nuestra serie representan el 92,18 %, ellos no siempre explican la sintomatologia. Por lo tanto, es importante la interrelacion con el cirujano para determinar cuales son las anomalas clinicamente relevantes en cada caso. (autores)}
