In case of a premature placenta abruption, diagnostics should be done quickly, because it affects survival and viability of a foal. Premature detachment of the placenta in the mares, which occurs before or during birth, is not a common parable. This pathological condition ranges from 5 to 10% of all cases of abortion, the birth of dead fetuses and perinatal mortality in horses. The general condition of a mare usually is without any abnormalities. Clinical obstetric examination includes vaginal and sonographic study. When conducting a vaginal examination, it is possible to see an open cervix and placenta bulging in a vagina. Sonography of an uterus enables to determine location of the placenta abruption and its volume. Typical symptoms of a premature abruption of a placenta in mares become visible only when foaling. For foaling with placenta previa typical is absence of ejection of amniotic fluid (allantois fluid) at the beginning of the second stage of foaling as chorioallantois remains intact. Fetus, all shells and fluids that are contained in a holistic chorioallantois, come out at once. In afterbirth of mares with premature placental abruption changes in structure of membranes are clearly observed. This pathological condition may significantly influence the unborn foal in the neonatal period. For mares, foaling with a diagnosis of premature placental abruption does not pose any danger. One of the most important factors in treatment is immediate dissection of chorioallantois and evacuating the fetus.
