Horses that have been retired from racing or imported from abroad are retired as broodmares. Whether at private farms or government institutes they are bred to stallions with the aim of improving fertility and enhancing the breed. Accidental deaths as a result of surgical or obstetrical complications lead to decreased productivity and economic losses to the horse breeding industry. Intussusception of the uterine horn is a frequent complication of the equine and bovine species, but rarely seen in other species. The most common causes are thought to be tearing of the placenta which is suspended from the uterus and ovaries and the weight of the placenta. Expulsion of the embryonic membranes is also thought to be a contributing factor. If symptoms are minor and treatment affected quickly, the problem will likely resolve itself. In more severe cases the uterus will prolapse completely. This case study was observed in a Thoroughbred broodmare. After treatment of dystocia, the broodmare could not stand up. She became dehydrated, collapsed, suffered colic and was euthanised. In this case was observed serious swelling vulva and perineal region by morphology, and there was seldom ascites and unusual view in thoracic and abdominal cavity after opening abdomen. However, intussusception of uterine horn involuted left uterine horn into the uterine body was observed.
