Abstract

Background & Objective: A number of procedures have been developed for multifetal pregnancy reduction (MPR) to reduce the overall number of fetuses in the gestation and improve the maternal outcomes as well as the outcomes of the surviving fetus. Materials & Methods: An observational historical cohort study was conducted on multiple pregnancies that underwent fetal reduction in Shariati Hospital and Omid Clinic between January 2018 and September 2021. The study population was divided into two groups according to gestational age at fetal reduction: 11–14 weeks' gestation (early reduction group) and 15–19 weeks’ gestation (late reduction group). The main outcome measures were the rates of pregnancy complications, pregnancy loss, preterm delivery, and adverse neonatal outcomes. Results: The study group included 107 patients with twin and multiple pregnancies that underwent abdominal MPR at 11-19 weeks’ gestation (79 in the early reduction group and 28 in the late group). The incidence of pregnancy complications (hypertension, diabetes, intrauterine growth disorder, preterm delivery, and pregnancy loss) was not significantly different between the two groups (P >0.05). The percentage of NICU admission was higher in the early reduction group compared to the late group (49% vs 18.5%, P=0.004). The weight of the first newborn was significantly heavier in the late versus early reduction group (2680.55±777.52 vs 2264.4±796.82, P=0.005). Conclusion: According to the present study, fetal reduction in twin or multiple pregnancies is a safe procedure with good obstetric outcomes if done by an expert specialist, especially when it is performed in the second trimester. © 2023, This is an original open-access article distributed under the terms of the Creative Commons Attribution-noncommercial 4.0 International License which permits copy and redistribution of the material just in noncommercial usages with proper citation.
