Heterotopic Pregnancy After In Vitro Fertilization Ending with a Successful Term Labor, a Case Report

Introduction: Heterotopic pregnancy is defined as the simultaneous presence of intrauterine and ectopic pregnancies, manifesting with abdominal pain and vaginal bleeding. Previous tubal surgeries and pelvic inflammatory diseases increase the risk of this anomaly. In this case report, heterotopic pregnancy after in vitro fertilization (IVF) in an 18-year-old female was reported. Case Presentation: An 18-year-old female was referred to our medical center, presenting with abdominal pain and vaginal bleeding. She had IVF pregnancy seven weeks ago without a history of any other illness or consuming a specific drug. According to ultrasound results, heterotopic pregnancy was diagnosed. Therefore, we decided to perform the salpingectomy and laparotomy of the fetus. The patient had a normal delivery via cesarean section at term (the 38th week of pregnancy). The patient remained stable without any further referral for the mentioned condition. Conclusions: Due to the importance of heterotopic pregnancy and its prevalence among women using fertility procedures and assisted reproduction techniques (such as IVF), even in the presence of a gestational sac containing yolk sac and after the detection of the embryo in the endometrium cavity, the adnexa should be well checked to rule out heterotopic pregnancy to obviate the risk of abortion and other fatal outcomes.
