Vanishing Twin Phenomenon in Dichorionic Triamniotic Triplet Pregnancy Presenting as Threatened Abortion: A Case Report
Abstract: Vanishing twin syndrome refers to spontaneous intrauterine demise of one or more fetuses in a multifetal gestation followed by partial or complete resorption of the demised fetus. The phenomenon is increasingly recognized with the widespread use of early ultrasonography and the rising incidence of multifetal pregnancies. Higher-order multiple gestations complicated by vanishing fetuses are uncommon and present unique diagnostic and management challenges. We report a rare case of dichorionic triamniotic triplet pregnancy presenting as threatened abortion, where two fetuses underwent spontaneous intrauterine demise with subsequent resorption. A 27-year-old gravida 3 para 1 living 1 abortion 1 woman presented at 18 weeks of gestation with vaginal spotting. Ultrasonography revealed dichorionic triamniotic triplet gestation with one viable fetus and two demised fetuses. The patient was managed conservatively with close maternal and fetal monitoring. Pregnancy progressed uneventfully and resulted in favourable maternal and neonatal outcome. This case highlights the importance of early ultrasound diagnosis, careful counselling, and expectant management in dichorionic pregnancies complicated by vanishing twin phenomenon. Conservative management with regular follow-up can lead to successful pregnancy outcome when one fetus remains viable.
