Multifetal Pregnancy Reduction of Trichorionic Triplet Gestations: What is the Benefit?

Objective This study aims to determine the efficacy of multifetal pregnancy reduction (MFPR) in improving obstetrical outcomes for trichorionic triplet gestations. Study Design Retrospective cohort study of patients with multiple gestations delivered by a single maternal-fetal medicine practice from 2005 to 2016. We compared patients with trichorionic triamniotic triplet gestations who underwent MFPR to those with an ongoing triplet pregnancy (TT), as well as primary dichorionic diamniotic twin gestations (DD). Logistic regression analysis was used to control for any differences at baseline. Results There were 42 patients in the MFPR group, 43 women in the TT group, and 693 women in the DD group. Comparing MFPR to TT, the likelihood of preterm birth Conclusion In trichorionic triamniotic triplet pregnancies, our study suggests that obstetrical outcomes may not be as dramatically improved with MFPR as seen in older studies.
