Relatório do Estágio Supervisionado Obrigatório (ESO), realizado na área de reprodução equina no município de Moreno - PE e Agreste Central do estado de Pernambuco, nas áreas de clínica, cirurgia e reprodução no Hospital Veterinário da Universidade Federal Rural de Pernambuco, município de Recife - PE, Brasil. Ovariectomia unilateral em égua com infertilidade idiopática - Relato de caso

Abstract

The Compulsory Supervised Internship (ESO), a compulsory subject in the last term of the Veterinary Medicine course, took place in two stages: the first was in the field, in the area of equine reproduction, with Dr. Sandra Victalino at 6 properties in the municipality of Moreno, located in the Metropolitan Region of Recife-PE, and in the municipalities of Chã Grande and Gravatá, both located in the Central Agreste region of Pernambuco, between the dates of 06/05/2023 and 07/21/2023. The second stage of the internship took place at the Large Animal Outpatient Clinic (AGA) of the Department of Veterinary Medicine (DMV) of the Federal Rural University of Pernambuco (UFRPE), in the area of clinic, surgery and reproduction, from 07/24/2023 to 08/30/2023, from Monday to Friday, accounting for a total of 420 hours of supervised internship. During the ESO period, students were supervised by Prof. Dr. Gustavo Ferrer Carneiro, professor at UFRPE, and by two supervisors, one for each period: Dr. Sandra Lacet Victalino Mancebo and Prof. Dr. Sandra Regina Fonseca de Araújo Valença, professor at UFRPE. The ESO period allows students to have more autonomy in directing their internship towards the area in which they feel the most affinity or even use this period to try out new areas that they did not have the opportunity to during their undergraduate studies. In this way, the aim of this work is to report on the activities carried out during the ESO period, as well as to report on a case monitored during this period concerning a mare, who is currently 5 years old and who, since she reached reproductive age, has been unsuccessful in her reproductive activity After a few years of assessment and detailed hormonal testing and imaging, the mare presented an hypertrophy of right ovary with a suspicion of a granulosa cell tumor. As a result of this suspicion and the fact that the donor mare was unable to cycle, the decision was made to perform a unilateral ovariectomy in an attempt to return the contralateral ovary to normal hormonal activity. After a histopathological examination, the ovary showed a neoplasm of the sex cord, suggestive of Tecoma. Based on this diagnosis, new treatment attempts will be made in order to promote physiological hormone production in the contralateral ovary.
