Megaesófago secundário adquirido em cão - Relato de caso

Abstract

Megaesophagus is a disorder that generates esophageal dilatation and hypomotility, and may be of primary or secondary origin depending on factors related to age, secondary diseases or undefined causes. The objective of this study was to report a case of secondary megaesophagus acquired in a dog suspected of infection with the male and female Border Collie virus, one year and five months old, which was referred to the Small Animal Clinic of the Veterinary Hospital of the Federal University of Uberlândia, presenting recurrent pictures of vomiting, one month after having attended and discharged from the disease distemper. In the anamnesis the animal was alert and with good body score, but presented myoclonus, suspected sequels due to the neurological phase of distemper. After being treated for acute gastritis, and the frequency of "vomiting" increased, we chose to perform contrast-enhanced radiography of the esophagus, thus diagnosing the secondary megaesophagus acquired. Conservative dietary management was instituted by offering food on a raised platform and keeping the animal in this position for 10 minutes after ingestion of food. In the case reported, it was possible to obtain a total improvement of the clinical signs of the animal.
