SUCCESSFUL PREGNANCY AFTER PARTIAL HYSTERECTOMY IN 2 MARES

Infertility was associated with a uterine mass in 2 Thoroughbred mares . Both mares had produced live foals, but had been barren for 2 years, despite repeated breedings. Each mass was removed through a right ven tral paramedian incision. Histologic examination of the masses reveale d a leiomyoma and an ovarian abscess. In 1 mare, approximately 30% of 1 uterine horn was removed because of tumor attachment; in the other m are, approximately 50% of 1 uterine horn was removed because of adhesi ons to the ovarian abscess. Pregnancy information was available for bo th mares for the 3 years after surgery; each mare had produced 2 healt hy foals and was pregnant with a third.
