Unilateral uterine torsion in a preparturient Boer Bull bitch resolved by caesarian section and unilateral cornuectomy

Abstract

Uterine torsion is a rare finding in dogs and most often presented with a life-threatening condition. We hereby report a case of unilateral uterine torsion in a three-year old, pregnant bitch, two days to its expected date of delivery. The bitch became anorexic about two days prior to presentation and lumps of blood from vulva were found inside its kernel on the morning of presentation. The physiological parameters, except the rectal temperature (38.70C), were all outside the normal range for dogs. Haematology investigation revealed a packed cell volume (PCV) of 20% and hence, the need for haemaccel® administration. Digital evaluation of the birth canal with the middle finger only revealed a foetus with normal anterior presentation but no cervical dilation. Ultrasonography showed two live foetuses at the pelvic region of the bitch. Caesarean section was conducted according to standard technique to save the two puppies in the left contralateral horn. The right uterine horn was twisted along its longitudinal axis over 360o in a clockwise direction from inter-cornual junction. It had two dead foetuses and was filled with over 5 litres of clotted blood/dark fluid with a lot of necrotic tissue. The dead foetuses were removed and the right horn was excised after due consultation with the owner. The surgical incisions were closed according to standard techniques. Our timely intervention to do caesarean section and right unilateral cornuectomy saved the bitch and the two foetuses in the contralateral intact horn and partially preserved the reproductive potential of the bitch.
