Abstract

The incidence of ectopic pregnancy is increased since in vitro fertilization-embryo transfer (IVF-ET) has started. And because of the possibility of combined pregnancy after IVF-ET, bilateral adnexal area and other portion of pelvis should be examined carefully by transvaginal ultrasonography during follow-up period. The rate of combined pregnancy after IVF is estimated to be as high as 0.2~1%. Since the incidence of combined pregnancies is markedly higher with IVF, special attention to this possibility after ET is warranted. According to a recent report, the occurrence of interstitial pregnancy is estimated to be 1:3600 for all pregnancies achieved with IVF. The prevalence of interstitial pregnancies is 2~4% of ectopic pregnancies. Interstitial pregnancies tend to be diagnosed later than most other ectopic pregnancies, and if uterine rupture occurs, the resulting hemorrhage can be severe. Currently, about 2% to 3% of interstitial pregnancies are thought to carry a maternal death, which is twice that of other tubal gestations. We report a case of simultaneous left tubal and right interstitial pregnancies after IVF-ET with a brief review of literature.
