Cranial vaginal and caudal uterine lacerations are a potential complication during or after parturition in mares. Vaginal tears can also occur after breeding accidents when the stallion's penis penetrates the cranial vaginal fronix. In cases associated with parturition, clinical signs may include mild hemorrhage, evisceration into the vagina and vulva, and penetration of the foal's head and/or legs into the peritoneal cavity. After breeding, the vaginal tears may not be identified immediately. Hemorrhage may be noted coming from the vulva. In some cases, the bowel may eviscerate into the vulva.
