Uterine prolapse in a mare leading to metritis,systemic inflammatory response syndrome,septic shock and death

This Case Report describes severe complications associated with uterine prolapse in a mare. A 6‐year‐old Trakehner mare was examined for depression, moderate pain and vaginal discharge 3 days after correction of a uterine prolapse. The clinical examination and haematology revealed that the mare had an infection with systemic inflammatory response syndrome and shock. Due to the uncontrollable, persistent pain, an exploratory celiotomy was performed which revealed severe metritis. During anaesthesia, the mare developed severe cardiovascular compromise and died in recovery. In previously reported cases of uterine prolapse in the mare, the authors warn of uterine injury, broad ligament haemorrhage, metritis, endotoxaemia and laminitis but often have a successful outcome with conventional therapy. This case describes a mare that developed severe complications and death after uterine prolapse. Mares with uterine prolapse require appropriate treatment and vigilant monitoring post treatment to prevent life threatening complications.
