Torção de corno uterino direito associada a metrite crônica em cadela não gestante: relato de caso

Abstract

Uterine torsion is a rare condition in bitches, especially non-pregnant ones, with reports of involvement of one or both horns. Despite being uncommon, this pathology affects entire females of different age groups, sizes and breeds, coursing with nonspecific clinical signs and demanding rapid veterinary intervention, due to the potential risk of death of the patient. This report aims to describe a case of right unilateral uterine torsion of 720º associated with chronic metritis in a fifteen-year-old, non-pregnant mixed-breed bitch, attended at the Veterinary Hospital of the Federal University of Uberlândia (HV-UFU). The animal had a history of recurrent pseudocyesis, a previous pregnancy and administration of contraceptive medication. At the time of consultation, she had an acute abdomen, in addition to increased abdominal volume, lack of appetite and yellowish vaginal secretion. The diagnoses of uterine torsion and chronic metritis were possible based on the association of complementary hematological and imaging tests, especially abdominal ultrasonography, when a cavitary mass was visualized in the middle abdomen and the right uterine horn with content and shape different from the usual, exploratory laparotomy and histopathology of the affected uterine horn. In view of this, this was one of the rare cases of torsion of the uterus in a non-pregnant bitch present in the scientific literature and that can help the veterinary clinical-surgical evaluation of patients who have a similar history and symptomatology.
