Survival and fertility of Thoroughbred broodmares with uterine tears treated surgically: 76 cases (2000-2023).

Prompt surgical repair of periparturient uterine tears yields high survival and preserved fertility in Thoroughbred mares.

This retrospective observational study evaluated 76 Thoroughbred broodmares with periparturient uterine tears treated surgically at a tertiary equine referral hospital from 2000-2023. Short-term survival to hospital discharge was 86.8% (66/76 mares). Long-term survival data available for 60 of 74 mares (81%) demonstrated favorable outcomes beyond one year post-discharge. Reproductive outcomes were particularly encouraging: of 31 mares rebred during the same year as their uterine tear, 87% (27/31) conceived and 74% (23/31) produced viable foals the following year. Postoperative complications and fertility data were comprehensively analyzed. The study demonstrates that prompt surgical intervention for periparturient uterine tears in Thoroughbred broodmares results in high survival rates and preserves reproductive capability. These findings support aggressive surgical management as the treatment of choice for this condition, offering mare owners reasonable expectations for both survival and future breeding potential.
