First-trimester multifetal pregnancy reduction using potassium chloride (KC1) injections or transcervical aspiration resulted in a 70% live birth rate with mild fetal morbidity and no maternal complications.

Area of Science:

  • Maternal-Fetal Medicine
  • Reproductive Surgery
  • Obstetrics

Background:

  • Multifetal pregnancies increase risks for both mother and fetuses.
  • Selective multifetal pregnancy reduction is a procedure to improve pregnancy outcomes.
  • Early intervention is crucial for managing high-order multiples.

Purpose of the Study:

  • To evaluate the safety and efficacy of first-trimester multifetal pregnancy reduction.
  • To assess pregnancy outcomes following selective fetal reduction.
  • To determine the rates of miscarriage, live birth, and fetal/maternal morbidity.

Main Methods:

  • Conducted multifetal pregnancy reductions in 26 patients during the first trimester.
  • Utilized transabdominal intrathoracic potassium chloride (KC1) injections in 23 cases.

  • Employed transcervical aspirations in 3 cases for fetal reduction.

    • Main Results:

    • Achieved live births in 18 of 26 pregnancies (approximately 70% live birth rate).
    • Observed 4 miscarriages (15%) during the second trimester.
    • Reported no maternal morbidity and mild fetal morbidity associated with the procedures.

    Conclusions:

    • First-trimester multifetal pregnancy reduction is a safe and effective procedure.
    • Selective fetal reduction can lead to improved pregnancy outcomes in multifetal gestations.
    • The methods used demonstrated acceptable rates of fetal survival and low complication rates.
