Hydramnios, a condition of excessive amniotic fluid, led to uterine rupture in a pregnant mare. The fetus was found in the abdomen, separated from the fluid due to amniotic sac torsion.

Area of Science:

  • Reproductive Medicine
  • Veterinary Science

Background:

  • Pregnancy in mares can be complicated by various conditions.
  • Uterine rupture is a rare but severe complication during equine pregnancy.

Observation:

  • An 18-year-old mare presented with acute abdominal pain.
  • Abdominocentesis revealed large volumes of bloody fluid.
  • Vaginal examination showed a dilated cervix and uterine blood.
  • Rectal palpation indicated a distended uterus.
  • Ultrasonography confirmed a dead fetus within the abdominal cavity.

Findings:

  • Necropsy confirmed uterine rupture and fetal expulsion into the abdomen.
  • The amniotic sac contained approximately 96 liters of fluid.
  • Torsion of the amniotic sac had separated the fetus from the fluid.

  • Hydramnios was diagnosed as the cause of excessive amniotic fluid accumulation.

    • Implications:

    • This case highlights hydramnios as a critical risk factor for uterine rupture in pregnant mares.
    • Early diagnosis and management of hydramnios are crucial for mare and foal survival.
    • Understanding the mechanisms of amniotic sac torsion is important for predicting complications.
