Uterine Torsion is a low casuistic condition in horses, which confers significant risk of life for pregnant mare and fetus. Occurring in the last gestational semester, the predisposing factors are not well defined, but the fetal and maternal characteristics stand out. Easily confused with Colic Syndrome due to similar clinical signs, an assertive assessment during transrectal palpation can differentiate and even define degrees of uterine torsion. Correctable by different techniques, the prognosis changes according to the variables in each case. The objective of this study is to report a clinical-surgical case of a mare that went through laparotomy surgery via the right flank to correct uterine torsion, at Hospital Veterinário Equicenter.
