Uterine torsion of 720 degrees in a midgestation cow.

A 720 degrees uterine torsion was diagnosed in a cow at 161 days of gestation. The uterine torsion was reduced by laparotomy and intra-abdominal manipulation. An emphysematous fetus was removed vaginally. The cow was treated medically for associated metritis and peritonitis. Uterine torsions in cattle most commonly occur at parturition and only rarely exceed 360 degrees.
