A 3 year old, Boer doe in late gestation was presented for an elective Cesarean section due to a previously diagnosed abdominal wall hernia. She was estimated to be 147 days pregnant, based on date of artificial insemination. Physical examination, abdominal ultrasonography, blood chemistry analyses and complete blood count were done; there was a mild anemia, but no other significant findings. Twelve hours after Cesarean section, the patient was dull and on further examination was tachycardic, tachypneic and anemic with a packed cell volume of 10%. Two liters of whole blood were transfused. Differential diagnoses included hemoabdomen or hematometra. Next day an exploratory laparotomy was performed and revealed a distended, blood-filled uterus, confirmed to be a hematometra. Medical therapy included intravenous fluids, aminocaproic acid, pantoprazole, antibiotics, and antiinflammatories. Subsequent follow up revealed that the patient had resumed normal behavior.
