Resumo
A coluna vertebral é responsável pela mobilidade, flexibilidade, absorção de choques e proteção da medula espinhal, que é de grande importância no sistema nervoso central. A doença do disco intervertebral toracolombar é uma enfermidade neurológica frequentemente descrita em cães, seus sintomas incluem paraparesia, paraplegia, incontinência urinária e perda da capacidade perceptiva de dor profunda. Essas discopatias podem ser classificadas entre Hansen tipo I, II e III. O diagnóstico é feito por meio de anamnese, sinais clínicos, exame neurológico e exames de imagem, onde a tomografia computadorizada é a preferida atualmente na medicina veterinária. Este artigo tem como objetivo descrever um relato de caso de recidiva do disco intervertebral em um cão sem raça definida atendido no Hospital Veterinário Santa Vida, o paciente apresentava paraparesia não ambulatória e através do exame de tomografia computadorizada o paciente foi diagnosticado com doença do disco intervertebral entre L1-L2. A cirurgia de escolha foi a hemilaminectomia, com pré, trans e pós cirúrgicos estáveis. Após 15 dias o paciente retorna com reaparecimento de sinais clínicos, onde foi indicado nova tomografia computadorizada, que constou uma recidiva da extrusão de disco no local anteriormente operado, porém do lado oposto. A técnica realizada foi de descompressão pela janela cirúrgica anterior. A recuperação pós cirúrgica foi estável, porém, o acompanhamento do caso clínico deste animal se mostrou inviável, já que o mesmo morava em outro estado. Com base neste relato, observa-se que a não realização da fenestração discal, que é uma importante técnica realizada após a hemilaminectomia, pode ter sido a causa da recidiva, visto que houve a permanência de conteúdo no interior do espaço intervertebral.
A spinal column is responsible for mobility, flexibility, shock absorption, and protection of the spinal cord, which is of great importance in the central nervous system. Thoracolumbar intervertebral disc disease is a neurological condition often described in dogs, with symptoms including paraparesis, paraplegia, urinary incontinence, and loss of deep pain perception. These discopathies can be classified as Hansen types I, II, and III. Diagnosis is made through medical history, clinical signs, neurological examination, and imaging, with computed tomography currently preferred in veterinary medicine. This article aims to describe a case report of recurrent intervertebral disc disease in a mixed-breed dog treated at Santa Vida Veterinary Hospital. The patient presented with non-ambulatory paraparesis, and computed tomography revealed intervertebral disc disease between L1-L2. Hemilaminectomy was the chosen surgery, with stable pre-, intra-, and postoperative periods. After 15 days, the patient returned with a recurrence of clinical signs, leading to a new computed tomography that showed a disc extrusion recurrence at the previously operated site but on the opposite side. Decompression was performed through the anterior surgical window. Postoperative recovery was stable, but clinical follow-up for this animal became unfeasible as it resided in another state. Based on this report, it is observed that the failure to perform disc fenestration, an important technique after hemilaminectomy, may have caused the recurrence, as there was a persistence of content within the intervertebral space.
