Trans-abdominal fetal reduction in higher order multiple pregnancies: a pioneer cohort retrospective study in Nepal.

Abstract

To share the initial experience of trans-abdominal multifetal pregnancy reduction (MFPR) in Nepal. The procedure was performed in 108 patients in a private hospital over a period of 3 years. Under ultrasound guidance, intracardiac injection of 0.2-3.0ml of 15% w/v (2mEq/ml) potassium chloride (KCl) was administered via trans-abdominal route. A total of 108 fetal reduction procedures were carried out at the seventh to fifteenth weeks of gestation, a maximum of 44 (40.7%) of which were done at the ninth to tenth weeks of gestation. A total of 123 fetuses were reduced. Out of total 108 multifetal pregnancies, 96 (88.8%) were due to in-vitro fertilization (IVF). Eighty-five pregnancies (78.7%) underwent reduction from triplet to twin. The second-time reduction was needed in five cases. Two attempts (in the same sitting) were required in three cases. The inadvertent demise of the second fetus was noted in three cases of dichorionic tri-amniotic triplet pregnancy. Ultrasound-guided trans-abdominal fetal reduction performed between the seventh and twelfth weeks of gestation is safe and effective.
