This report describes the diagnosis and treatment of a case of unilateral uterine torsion, which was detected at the caesarean section of a pregnant bitch. A one-year-old, 34 kg half-breed Kangal dog, with signs of apathy, anorexia and emesis for the past two days was the material of this case report. The dog only displayed a mild apathy. Mucous membranes colour, capillary refilling time, heart and respiratory rates were within the physiological ranges. The body temperature was 37.5°C. A mucoid brown-greenish coloured vaginal discharge was determined. The measured biochemical values fell within the physiological ranges. Both live and dead foetuses were determined ultrasonographically then the number of dead foetuses increased half an hour later on second ultrasonographic examination so it was decided to perform a caesarean section. One female and two male live foetuses from the right uterine horn and two dead female foetuses from the left uterine horn were removed. The left uterine horn displayed hyperaemia, haemorrhage and fragility with a 1800° torsion along its long axis, near the uterine bifurcation. The amniotic fluids appeared normal, the chorioallantoic fluid was haemorrhagic in the left horn. Total ovariohysterectomy was performed. The uterine torsion cases may be manifested with nonspecific clinical signs such as anorexia and emesis. In the event of increased number of dead foetuses in repeated ultrasonographic examination, the presence of uterine torsion should be considered. In such cases, the pregnant animal can be saved by surgical intervention, as was in this case study.
