Spontaneous Haemoperitoneum in Pregnancy with Placenta Percreta in Bicornuate Uterus with Successful Pregnancy Outcome: A case study.

Intraperitoneal haemorrhage during pregnancy or postpartum without any history of trauma (spontaneous haemoperitoneum in pregnancy [SHiP]) is a rare condition, causing significant morbidity and mortality for the mother and the neonate. We report a 27-year-old female patient with SHiP at 31 weeks of gestation who was referred to a tertiary care hospital in Muscat, Oman, in 2019, with right iliac fossa pain, pallor and tachycardia. Radiological investigations revealed intraperitoneal bleeding and a right adnexal haematoma. She was managed conservatively with blood transfusion and supportive care. At 36 weeks of gestation, lower segment caesarean section was done and a live baby with good Apgar score was delivered. Pre-operatively, she was found to have a bicornuate uterus, placenta percreta at the junction of the horns and a right adnexal haematoma. This case highlights the significance of thorough evaluation of acute abdominal pain in pregnancy in avoiding unnecessary surgical intervention and iatrogenic prematurity.
