OBJECTIVE: To report a case of a heterotopic primary abdominal pregnancy after two-blastocyst IVF-ET. DESIGN: Case report. SETTING: University-based IVF program. PATIENT(S): A woman with a heterotopic abdominal pregnancy after IVF-ET. INTERVENTION(S): Pituitary down-regulation with luteal antagon, ovulation induction with menotropins, IVF-ET, progesterone in oil for luteal support, dilation and curettage for missed abortion, laparoscopy, and resection of abdominal gestation. MAIN OUTCOME MEASURE(S): Human chorionic gonadotropin levels, pelvic ultrasound examinations, and laparoscopic and pathologic findings. RESULT(S): A heterotopic abdominal pregnancy occurred after a two-blastocyst IVF-ET. The concurrent intrauterine gestation resulted in a miscarriage. CONCLUSION(S): The number of embryos transferred has been identified as a powerful risk factor for heterotopic pregnancy; however, heterotopic pregnancy can occur following a two-embryo, blastocyst stage transfer.
