Rupture of bicornuate uterus

Mid-trimester spontaneous rupture of a bicornuate uterus: A case report

Bicornuate uterus (BU) is a rare congenital anomaly that may present with various obstetric complications, and very rarely may be a risk factor for uterine rupture, even of an unscarred uterus. A 21-year-old primigravida woman, at 19 weeks and 5 days of gestation, presented with severe abdominal pain and features of hypovolemic shock. Urgent laparotomy showed a large hemoperitoneum, a ruptured left horn of a BU and a dead fetus in the abdominal cavity. Excision of the ruptured left horn was performed and the uterine defect was sutured. Postoperative recovery was uneventful. Bicornuate uterus is a rare uterine anomaly and is associated with various obstetric complications at different gestational ages. Ruptured uterus should be considered in the differential diagnoses of acute abdominal pain and a picture of hypovolemia in women with mid-trimester pregnancies.

Case Report: Spontaneous perforation of a bicornuate uterus with concomitant sarcoma

A 47-year-old nulliparous, virginal woman presented to the emergency department with acute abdominal pain. Emergency pelvic ultrasound and abdominal CT were taken, which showed a significant amount of hemoperitoneum and a bicornuate uterus with about 18cm x 10cm mass on left uterus. Since the mass had increased vascularity and irregular margins, we thought that the mass could be a uterine sarcoma. MRI and PET/CT were taken additionally for oncologic evaluation before surgery. Intra operative findings showed a ruptured bicornuate uterus with a large mass within the left uterine horn. Total

abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Pathologic analysis confirmed an undifferentiated uterine sarcoma. She was treated with 6 cycles of chemotherapy(etoposide, ifosfamide, cisplatin) postoperatively. Chest and abdomen CT for follow up after chemotherapy showed no sign of cancer recurrence. We suggest a bicornuate uterus with concomitant sarcoma should be concerned as a possible cause of uterine rupture by reviewing this case.

Uterine rupture in a primigravid patient with an unscarred bicornuate uterus at term

Background

Uterine rupture of an unscarred primigravid uterus is an exceedingly rare event. Cases of spontaneous rupture of an unscarred bicornuate uterus have been reported, but typically occur in the first or second trimester.

Case

A 28-year-old primigravida at 37 weeks gestation with a known bicornuate uterus and no prior surgery underwent an emergent cesarean section after presenting with severe abdominal pain and signs of fetal compromise. She was found to have a uterine rupture with the fetus free in the abdomen accompanied by a large hemoperitoneum. Both mother and baby did well postoperatively.

Conclusion

Bicornuate uterus may be an independent risk factor for uterine rupture, which can occur in primigravid patients and at any gestation.

•

A case of uterine rupture in a term primigravid patient is presented.

•

Mullerian anomalies may be an independent risk factor for uterine rupture.

•

A bircornuate uterus warrants a higher index of suspicion for uterine rupture.

•

Early pregnancy sonographic examination helps in early detection of uterine anomalies.

•

Close follow up of the pregnancy in a BU is essential to early recognize adverse outcomes.

•

Uterine rupture can occur in early pregnancy in patients with uterine anomaly.

Introduction

Bicornuate uterus (BU) is a rare uterine anomaly result from incomplete fusion of the two Müllerian ducts during embryogenesis. BU very rarely can lead to rupture of the uterus during the early pregnancy with high mortality and morbidity rates.

Presentation Of Case

A primigravida in the first trimester (9 weeks) presented complaining of epigastric pain and vomiting for one day. Ultrasound scan was performed at the 7th week of pregnancy and showed a BU with single intrauterine gestational sac in the right horn. On presentation, the patient was pale and irritable. Urgent ultrasound scan showed viable fetus in the right horn, free fluids in Morrison’s pouch. Laparotomy showed BU with pregnancy in the ruptured right horn. The defect in the uterus was repaired. Postoperatively, the patient was advised to use contraceptive pills for one year.

Discussion

Our patient has a sonographic diagnosis of BU at the 7th gestational week. At that stage, nothing was done except close follow up of the pregnancy. When she developed severe epigastric pain, initially, we thought of peptic ulcer disease complications. Even after deterioration of the patients’ condition, the diagnosis was not clear as the urgent ultrasound showed a viable fetus. Blood and fluid replacement therapy, and exploratory laparotomy were essential to save the patient’s life.

Conclusion

This case highlights the fact that uterine rupture can occur in early pregnancy when associated with uterine anomaly. Early sonographic diagnosis has a major contribution in evaluation and management.
