Uterine torsion is one the most critical conditions affecting pregnant mares in last trimester of pregnancy. The current study was advocated for precise diagnosis of uterine torsion in mares and accordingly application of suitable method of treatment. The study comprised 12 Straight Egyptian Arabian mares suffered from uterine torsion (5-11 months of gestation). Diagnosis was based on symptoms which were intermittent signs of colic, straining and frequent lifting of upper lip. Clinical examination has been applied through rectal examination for detection of direction of broad ligament (clockwise and counterclockwise directions). Blood biochemistry was carried out and only CRP (C-reactive protein) was elevated in 25% of cases. Ultrasonography was used for detection of fetal viability through rectal and transabdominal scanning. The results of rolling method was 33.3% live newborn and 66.6% live dams whereas 66.6% live newborn and 83.2% live dams for flank laparotomy. Consequently, flank laparotomy was preferred than rolling method. There were some complications of treatment such as abortion or death of the dam due to uterine rupture. In conclusion, uterine torsion in mares is a serious problem should be diagnosed as early as possible for obtaining good results of treatment as well as standing flank laparotomy is more preferred than rolling method for getting a good results.
