Mielopatia constritiva em pug - relato de caso

Abstract

Vertebral malformations are the result of defects in formation or segmentation and occur frequently in Pug breed dogs. The aim of this study is to describe the clinical, diagnostic and therapeutic aspects of constrictive myelopathy associated with dysplasia of the caudal articular process in a Pug breed dog. A nine-year-old male Pug dog with alterations in its pelvic limbs was admitted to the Veterinary Hospital of the Federal University of Minas Gerais. The patient had ambulatory paraparesis, proprioceptive ataxia, proprioceptive deficits and urinary and fecal incontinence. Magnetic resonance imaging and computed tomography scans of the patient showed dysplasia of several caudal articular processes, spinal cord compression and hypersignal adjacent to the aplasia of the caudal articular process of T12. The treatment was a surgical laminectomy with excision of anomalous tissue in the T12-T13 interarch space that was compressing the spinal cord and bilateral vertebral stabilization with titanium plates. In the immediate post-surgery period, the patient developed paraplegia with superficial sensitivity, but follow-up for a longer period was not possible due to its premature death in a different clinic.
