Case:
A 39-year-old woman presented with a genital hemorrhage at 5 weeks of gestation after an artificial cycle double frozen-thawed embryo transfer. She was diagnosed with a cervical heterotopic pregnancy. Although hormone supplementation was discontinued to terminate the pregnancy at 5 weeks of gestation, the intrauterine and cervical gestational sacs continued to develop.
Outcome:
The cervical gestational sac was surgically removed and the intrauterine pregnancy continued uneventfully, except for vasa previa. At 36 weeks of gestation, the patient underwent a cesarean section and gave birth to a healthy female infant. At the delivery, massive bleeding occurred and a hysterectomy was performed due to total placenta accreta.
Conclusion:
This case provides a novel example of a near-term delivery after a cervical heterotopic pregnancy and emphasizes the need for intensive care, even after the successful management of a cervical pregnancy. Most importantly, the present case implies a possible link between hormonal withdrawal and abnormal placentation.
