Summary

Selective fetal reduction safely reduces the number of fetuses in multiple pregnancies, decreasing complications. This procedure, performed early in gestation, leads to healthy births and ongoing pregnancies with minimal adverse events.

Area of Science:

  • Reproductive Medicine
  • Maternal-Fetal Medicine
  • Obstetrics

Background:

  • Assisted reproductive technologies increase pregnancy rates but also the risk of multiple pregnancies and associated complications.
  • Reducing the number of developing embryos is crucial for mitigating obstetrical risks in multiple gestations.

Purpose of the Study:

  • To evaluate the safety and efficacy of selective fetal reduction in women with high-order multiple pregnancies.

Main Methods:

  • Eight women with multiple pregnancies (triplets to octuplets) underwent selective fetal reduction.
  • Sonar-guided injection of demerol and xylocaine into the fetal thorax was performed between 7-11 weeks of gestation.
  • Post-procedure scans over three days confirmed the viability of remaining fetuses.

Main Results:

  • The procedure resulted in 10 healthy births from six pregnancies, with two ongoing pregnancies.
  • No serious complications were observed, apart from cases of vanishing twins.

Conclusions:

  • Selective fetal reduction is presented as an easy, safe, and effective method to reduce obstetrical morbidity in multiple pregnancies.
