ABSTRACT:
The aim of this study was to identify dogs with thoracolumbar intervertebral disc disease (Hansen type I) submitted for surgical treatment on a routine service in neurology in a university veterinary hospital in 2006-2014, and to get information about age, sex, breed, site of extrusion, interpretation of myelography, evaluation of the degree of neurological dysfunction, functional recovery of these dogs, and to verify the recurrence of clinical signs of disease. The most common breed was Dachshund (69%), followed by mixed breed (14.5%). The most affected sites were between T12-T13 (31.9%) and L1-L2 (19.1%). Of the 110 dogs, 74 (67.3%) improved clinical signs after surgery, 54 (49.1%) satisfactory and 20 (18.2%), in part satisfactory. From these dogs, six (8.1%) dogs were in grade II, 19 (25.7%) in grade III, 35 (47.3%) in grade IV, and 14 (18.9%) in grade V. It can be concluded that satisfactory surgical treatment promotes functional recovery in most dogs with thoracolumbar disk extrusion. The prognosis for functional recovery after surgical treatment is better the lower the degree of neurological dysfunction and the recurrence percentage is lower in dogs subjected to this type of therapy.
