Heterotopic abdominal pregnancy following two-blastocyst embryo transfer.
OBJECTIVE
To report a case of a heterotopic primary abdominal pregnancy after two-blastocyst IVF-ET.


METHODS
Case report.


METHODS
University-based IVF program.


METHODS
A woman with a heterotopic abdominal pregnancy after IVF-ET.


METHODS
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.


METHODS
Human chorionic gonadotropin levels, pelvic ultrasound examinations, and laparoscopic and pathologic findings.


RESULTS
A heterotopic abdominal pregnancy occurred after a two-blastocyst IVF-ET. The concurrent intrauterine gestation resulted in a miscarriage.


CONCLUSIONS
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.
