Abstract

Heterotopic pregnancy is defined as coexistence of intrauterine and ectopic pregnancy. The reported incidence of heterotopic pregnancy, which is normally rare, is particularly high (1%) after IVF treatment. It is important to have a high index of suspicion for the occurrence of heterotopic pregnancies because only 40% to 84% of cases can be diagnosed with transvaginal ultrasound at the initial presentation. Edwards syndrome occurs in 8,000 newborns and the incidence is much higher in elderly gravidas. We report a case of heterotopic pregnancy following IVF-ET resulting in 16 weeks of intrauterine pregnancy with fetal Edwards syndrome, and tubal pregnancy with a brief review of literature.

Key Words: Heterotopic pregnancy, IVF-ET, Edwards syndrome, Mid-trimester
