Spontaneous fundal rupture in an unscarred uterus in a female with twin pregnancy after in-vitro fertilization: a case report

Introduction and importance:Spontaneous uterine rupture in an unscarred uterus is very rare. It is found to be rarer after in-vitro fertilization. It is associated with significant morbidity and mortality if not diagnosed and treated promptly. Case presentation:Thirty three years female with twin pregnancy following in-vitro fertilization after 11 years of marriage presented to emergency department with lower abdominal pain at 36 weeks 3 days of gestation and was planned for emergency caesarean section for precious twin pregnancy in labour. Clinical findings and investigation:She was vitally stable and on palpation of abdomen, there was generalized tenderness along with guarding. All the investigations were within normal limits. Intervention and outcome:Emergency caesarean section was performed under subarachnoid block which revealed a 6x2 cm fundal uterine rupture with no active bleeding which was repaired in layers. The babies were extracted with a lower uterine segment incision. First twin cried immediately after birth while the second one needed resuscitation and mechanical ventilation due to perinatal asphyxia. Conclusion:Even though rare in a previously unscarred uterus, uterine rupture can present in different forms and thus, requires vigilant evaluation of the patient and prompt intervention to avoid significant maternal or foetal morbidity and mortality.
