Summary

Multifetal pregnancy reduction to a singleton is now safer and may increase the likelihood of a successful birth. This procedure, particularly for older mothers, is being reconsidered due to improved outcomes.

Area of Science:

  • Maternal-Fetal Medicine
  • Reproductive Health
  • Obstetrics

Background:

  • Historically, multifetal pregnancy reduction to a singleton was reserved for severe maternal or fetal conditions.
  • An increasing number of women, particularly those over 40, are seeking counseling for singleton reduction.
  • This trend prompted a re-evaluation of previous clinical stances on the procedure.

Purpose of the Study:

  • To review the safety and outcomes of multifetal pregnancy reduction to a singleton.
  • To compare these outcomes with existing data on twin and singleton pregnancies.
  • To assess the viability of offering singleton reduction more broadly.

Main Methods:

  • A retrospective review of 52 cases of first-trimester twin-to-singleton multifetal pregnancy reduction performed by a single operator.

  • Comparison of outcomes with national register data for twin and singleton pregnancies.
  • Analysis of patient demographics, including advanced maternal age.

    • Main Results:

    • The study included a significant proportion of women aged 35 and older (40/52), with several over 40 and 50.
    • Fifty-one out of 52 pregnancies reached viability, with a mean gestational age of 37.2 weeks.
    • The miscarriage rate was 1.9% (1/52), which is lower than spontaneous loss rates in untreated twin pregnancies.

    Conclusions:

    • Multifetal pregnancy reduction to a singleton, once rare due to safety concerns, has demonstrated improved safety and efficacy.
    • The data suggest that reducing twins to a singleton can lead to a higher chance of a successful birth compared to continuing a twin pregnancy.
    • The study proposes that twin-to-singleton reductions be considered with appropriate safeguards and constraints.
