Delivery of a live newborn in a triplet pregnancy complicated by preeclampsia after intrauterine demise of two and expulsion of one triplet: a case report.

Delayed interval delivery in twin pregnancies is an unusual occurrence, even more so in triplet pregnancies. We report on a delayed interval delivery in a dichorionic triamniotic triplet pregnancy after in vitro fertilization (IVF). Because of severe twin to twin transfusion syndrome (TTTS), two fetuses demised at 22 weeks of gestation. One of the two fetuses spontaneously aborted at 25 weeks of gestation. The remaining live fetus and the second demised fetus were delivered by cesarean section 9 weeks later because of the occurrence of preeclampsia. This case indicates that delayed interval delivery in triplets is possible and that preeclampsia can occur after intrauterine demise of two fetuses.
