A novel case report of clockwise and counterclockwise uterine torsions during the same gestation period in a mare

Abstract

Uterine torsion (UT) is a common obstetrical problem in Straight Egyptian Arabian mares, causing a medical emergency for both the mare and the fetus. This case report describes, for the first time, the management of a case of UT in both directions during a single gestation period in a 5-year-old Straight Egyptian Arabian mare. The mare was 8 months pregnant and experienced intermittent unresponsive colic signs. Rectal examination revealed clockwise 180° UT and ultrasonography showed a viable fetus. The haematological findings were within the normal range. The mare was surgically treated immediately by standing flank laparotomy (SFL) on the right side. 4 days later, the mare was returned to the clinic with the same complaint. Rectal and ultrasonography examinations revealed counterclockwise 180° UT and a viable fetus. The animal was subjected again to SFL on the left side. After surgeries, the mare recovered well, foaled at term and gave birth to a viable filly. She was bred again and conceived. This case is documented to demonstrate the occurrence of a UT in both directions during the same gestation period in mares, as well as the efficacy of SFL in rectifying the condition and allowing both the mother and foal to survive.
