Background: Pyometra or pyometritis is a serious and common condition of intact female dogs characterized by the inflammation of the uterus with a buildup of purulent exudate. It may be classified as open or closed. If untreated, pyometracan lead to uterine rupture and sepsis. Pyometra may also predispose to uterine torsion, defined as a rotation of one orboth uterine horns around its longitudinal axis. Uterine torsion in female dogs is rare, and usually with late pregnancy orparturition. This case report describes the clinical presentation and therapeutic management of uterine torsion correlatedwith open pyometra in a non-gravid bitch with no history of exogenous progesterone exposure.Case: A 10-year-old intact Yorkshire Terrier bitch weighing 3.2 kg was referred to a veterinary clinic in Porto Alegre,Brazil, with a 7 day history of prostration, anorexia, polydipsia, and sanguinopurulent vulvar discharge. Physical examination revealed pronounced abdominal tenderness. On abdominal ultrasonography, the uterus was enlarged and filled withcellular anechoic content, suggestive of pyometra. A complete blood count showed mild microcytic normochromic anemiaand leukocytosis. The animal was stabilized and an urgent ovariohysterectomy was performed. Preanesthetic analgesiaconsisted of subcutaneous methadone 0.3 mg/kg. Anesthesia was induced with propofol 3 mg/kg i.v. and maintained withinhaled isoflurane. During the procedure, significant enlargement of the left uterine horn and slight enlargement of theright uterine horn were observed. In addition, a torsion was identified near the left ovary, with copious sanguinopurulentsecretion. The animal remained under observation and fluid therapy for 48 h after the procedure and was discharged topostoperative follow-up. After discharge, the following treatment was medicine, local cleaning and rest for 14 days. Concluding...(AU)
