Selective fetal termination for preeclampsia treatment in a dichorionic gestation with a triploid fetus: A case report

Background: Triploidy is commonly associated with the development of early-onset preeclampsia. While previ-able preeclampsia is often a contraindication to prolonging pregnancy, there may be rare circumstances in which an alternative approach may be offered.Case: A nulliparous patient with a dichorionic twin gestation, recently diagnosed triploidy in one twin, and history of chronic hypertension presented at 18 weeks of gestation with signs and symptoms suggestive of preeclampsia. After symptomatic therapy and laboratory evaluations, selective fetal termination of the affected twin was elected and performed without complications. The patient subsequently delivered a healthy newborn at 37 weeks of gestation.Conclusion: Selective fetal termination may be considered a management option for previable preeclampsia in a dichorionic gestation with triploid fetus and was associated with a favorable outcome in this case.
