Delayed Urethral Obstruction After Uterine Torsion in a Pregnant Dog

Simultaneous Torsion of a Uterine Horn and Spleen in a Pregnant Two-Year-Old Crossbreed Bitch: A Case Report

A pregnant 2-year-old mixed-breed dog was admitted with a 2-day history of lethargy, anorexia and painful abdominal distension. Clinical manifestations were unspecific and mainly suggested hypovolemic shock. Physical examination, ultrasonographic evaluation and radiographs confirmed mid-late pregnancy and evident signs of fetal death and peritoneal effusion. An exploratory laparotomy was immediately initiated which revealed torsion of the right gravid uterine horn over the left one and, simultaneously, the unexpected presence of splenic torsion and rupture, with a stretched omentum covering and exerting tension on the spleen's cranial pole. Histopathology revealed hemorrhagic infarction of the uterus and spleen. The animal recovered uneventfully and was later submitted to a preventive gastropexy.
