A 1-week-old Morgan filly was evaluated because of acute signs of abdominal pain of 7 hours' duration. On admission, physical examination findings were unremarkable; however, radiography of the abdomen revealed slight distention of the small intestine. Signs of abdominal discomfort were detected during several hours of observation. Abnormalities were not evident during gastroscopic evaluation. Therefore, exploratory laparotomy was performed. The only abnormal finding was infarction of the left ovary secondary to a 720 degrees torsion of the mesovarium. The vascular pedicle was ligated and the ovary was removed. Recovery from anesthesia and surgery was satisfactory, and the foal was discharged from the hospital 5 days after surgery. Two years later, it appeared to be clinically normal. Review of the recent veterinary literature failed to find reports of ovarian torsion as a cause of signs of abdominal pain in horses. Ovarian torsion should be considered as a differential diagnosis in fillies with acute signs of abdominal pain, especially when laparotomy fails to reveal abnormalities associated with the gastrointestinal tract.
一匹1周龄的摩根母马驹因持续7小时的急性腹痛症状接受评估。入院时，体格检查未发现异常；然而，腹部X光检查显示小肠略有扩张。在数小时的观察中检测到腹部不适的症状。胃镜检查未发现异常。因此，进行了剖腹探查术。唯一的异常发现是卵巢系膜发生720度扭转继发左卵巢梗死。结扎血管蒂并切除卵巢。麻醉和手术后恢复情况良好，马驹在手术后5天出院。两年后，其临床状况似乎正常。查阅近期的兽医文献，未发现有关卵巢扭转作为马匹腹痛症状原因的报道。对于出现急性腹痛症状的母马驹，应将卵巢扭转视为鉴别诊断的一种情况，尤其是在剖腹探查未能发现与胃肠道相关的异常时。
