Area of Science:

  • Reproductive Medicine
  • Maternal-Fetal Medicine
  • Genetics

Background:

  • Fetal reduction is a key intervention for managing multiple pregnancies.
  • Its use has surged with the rise of in vitro fertilization (IVF).
  • Improvements in ultrasound and reduced embryo transfers have influenced practice.

Purpose of the Study:

  • To evaluate the evolving role and success of fetal reduction in multiple pregnancies.
  • To assess the impact of advancements on fetal reduction outcomes.
  • To explore the benefits of genetic diagnosis and selective reduction strategies.

Main Methods:

  • Review of fetal reduction procedures over the past two decades.
  • Analysis of success rates correlated with increasing experience, technological improvements (ultrasound), and starting fetal numbers.

  • Inclusion of genetic diagnosis as a factor in outcomes.
  • Examination of outcomes for triplets or more, and twins.

    • Main Results:

    • Fetal reduction success rates have demonstrably improved.
    • Key factors contributing to success include enhanced operator experience, superior ultrasound technology, and lower initial fetal numbers.
    • Genetic diagnosis prior to reduction is associated with better overall outcomes.
    • Reduction of triplets or higher-order multiples leads to clear improvements.
    • Selective reduction of twins to a singleton is now a feasible approach.

    Conclusions:

    • Fetal reduction remains a critical tool for mitigating risks associated with multiple gestations.
    • Ongoing advancements continue to refine the safety and efficacy of fetal reduction.
    • Genetic screening and strategic reduction, including twin-to-singleton, represent significant progress in optimizing pregnancy outcomes.
