OBJECTIVE: Multifetal pregnancy reduction has been shown to improve outcomes in triplet and higher-order multiple pregnancies. The data for fetal reduction of twin pregnancies are limited. The purpose of this study was to compare adverse pregnancy outcomes in ongoing twin pregnancies compared with twin pregnancies reduced to singletons. STUDY DESIGN: This was a retrospective cohort study comparing dichorionic diamniotic twin pregnancies with dichorionic diamniotic twin pregnancies reduced to singleton gestations between 11 and 24 weeks' gestation in a single maternal-fetal medicine practice over a 9 year period...

The early determination of chorionicity in twin gestations is a critical factor in the management of twin gestations. While twins and higher order multiple gestations have increased risks of almost any complication of pregnancy, those pregnancies involving a monochorionic (MC) twin pair are at an especially high risk. The presence of vascular anastomoses within a MC placenta creates risk for discordant malformations, twin reversed arterial perfusion sequence, twin-to-twin transfusion syndrome, or severe selective intrauterine growth restriction...

OBJECTIVE: The objective of the study was to assess in trichorionic triplet pregnancies the effectiveness of elective reduction to twins. STUDY DESIGN: This was a nationwide retrospective cohort study. We compared the time to delivery and perinatal mortality in trichorionic triplet pregnancies electively reduced to twins with ongoing trichorionic triplets and primary dichorionic twins. RESULTS: We identified 86 women with reduced trichorionic triplet pregnancies, 44 with ongoing trichorionic triplets, and 824 with primary twins...

OBJECTIVE: To compare outcome of dichorionic-triamniotic (DCTA) triplet gestations with that of a paired cohort of monochorionic-diamniotic (MCDA) twin gestations undergoing laser therapy for treatment of twin-to-twin transfusion syndrome (TTTS). METHODS: All DCTA triplets treated at four referral centers between specified dates were included. A matched cohort group of MCDA twin gestations affected by TTTS was used for comparison. RESULTS: Sixteen sets of DCTA triplets treated with laser photocoagulation of placental anastomoses were compared with 32 matched sets of MCDA twins...
