Moaddab SH, Siavosh Haghighi ZM., Prepubic tendon and abdominal wall rupture in pregnant mares, Onl J Vet Res., 21 (12):798-803, 2017. Body wall ruptures are rare but can occur in late pregnancy. Predisposing factors include hydrops allantois, hydrops amnion, trauma, twins and fetal giants, but it is also seen in mares with normal pregnancy. Mares usually present very close to foaling with severe, ventral edema running cranially from the udder and, in many cases, involving the udder itself. Mares with prepubic tendon ruptures may be reluctant to move, show a saw horse stance (elevated tail head and ischial tuberosity), and the mammary glands may be displaced cranially or flattened. History, clinical signs, and outcome of four mares with prepubic tendon and abdominal wall rupture, are described. Old age, late pregnancy and inactivity, were considered as major risk factors for the condition.


Key words: prepubic tendon, abdominal wall, rupture, pregnancy, mare.
