title: [Heterotopic pregnancy with intrauterine dizygotic twins following embryo transfer in the blastocyst phase].
abstract: Ectopic pregnancy is a common complication of in vitro fertilization and embryo transfer (IVF-ET). On other hand, heterotopic pregnancy complicates 1-2% of all IVF-ET pregnancies. Tubal damage as reason for treatment and multiple embryo transfer might predispose patients to this complication. We present a successful treated case of an infertile patient that developed simultaneous twin intra- and single extra- uterine pregnancy after blastocyst-stage embryo transfer. In IVF-ET patients presence of an intrauterine gestation not exclude the possibility of a concomitant extrauterine pregnancy. Awareness of the possibility of heterotopic pregnancy after IVF-ET plays an important role in the successful treatment of this reproductive complication. Transfer of good quality embryos can be a risk factor to develop heterotopic pregnancy.
