Abstract

Highlights: When compared with triplet gestations managed expectantly, multifetal pregnancy reduction of triplet pregnancies to twins results in a later gestational age at birth. Multifetal pregnancy reduction does not increase the abortion rates. Multifetal pregnancy reduction does not increase the chance of live birth. Gestational week when fetal reduction was performed, the age of mother, the choice of fetus does not influence live and viable birth rates. Abstract: Objective: The management of multiple pregnancies is still a challenge. The aim of this study was to compare the outcome of triplet pregnancies managed expectantly or by multifetal pregnancy reduction to twins. Study design: For this retrospective, comparative and monocentric study, the medical files of all women with triplets who admitted to our institution over a 13-year period were examined. Women requesting multifetal pregnancy reduction to have twins formed the study group, and women with triplets who wished to continue their pregnancies formed the control group. Main outcome measures were durations of pregnancies presented as number of weeks gestation, abortion rates, term and preterm birth rates, fetal loss and live birth rates. Results: During the study period, 171 women with triplets admitted to our institution. One hundred fifty one patients are included in this study. Forty-five women carrying triplets wished to continue their pregnancies and 106 women requested multifetal pregnancy reduction to have twins. Fetal reduction of triplets to twins was associated with a significantly lower incidence of birth before 34th gestational week and higher incidence of late preterm and term birth rates without changing live birth rates. Conclusion: Multifetal pregnancy reduction of triplet pregnancies to twins resulted in a later gestational age at birth compared with the triplet gestations managed expectantly.
