Abstract

This is a retrospective study of uterine torsion (UT) in seven mares. In two cases, serum progesterone and estradiol concentrations were also investigated. The mare and foal/fetus survival rate was 57% (4/7). Four cases presented with clockwise torsion, and two cases presented with counterclockwise torsion. The direction was undetermined in one case. The degree of torsion varied. Correction of torsion was performed by ventral midline celiotomy in all cases. In the two cases with measured hormone levels, elevated levels of P₄ were decreased through medication. All mares discharged from the hospital with a live fetus were able to carry a live fetus. Early diagnosis and treatment of UT increases the possibility of helping mares and foals in cases with acute UT.
