Doença do disco intervertebral em cães : prevalência de casos no Hospital Veterinário Universitário em Cuiabá - Mato Grosso (2017-2024)

Abstract

Intervertebral disc disease is the most common disorder affecting the spinal cord in dogs. The aim of this study is to report the incidence of IVDD in dogs submitted to computed tomography. It is the first study based on a survey of dogs with IVDD in the state of Mato Grosso. A literature review was conducted on intervertebral disc disease in dogs and data on age, gender, breed, type of IVDD and location of the lesion were analyzed. The dogs underwent computed tomography at the Diagnostic Imaging Department of the Veterinary Hospital of the Federal University of Mato Grosso from May 25, 2017, to July 31, 2024. The demographic data of the dogs was collected from individualized records at HOVET - UFMT. The year with the highest number of cases was 2021, with 34.95%. The diagnosis of intervertebral disc extrusion was the most frequent, with 64.78%, and 56.91% were male. The age group with the highest incidence was the elderly (54.47%), represented by dogs aged 72 months and over. Dogs with a defined breed were most affected (84.43%), with the chondrodystrophic breeds, Shih-Tzu, French Bulldog and Lhasa Apso, being the most recurrent. The site most affected by IVDD was the thoracolumbar segment, at L3-L4. Disc extrusion mainly affected the T12-T13 and L3-L4 vertebrae, while protrusion was more common in the lumbosacral region, at L7-S1. It can be concluded that dogs with a defined breed and chondrodystrophic breeds are more likely to have disc extrusion.
