STUDY QUESTION: What are the pregnancy outcomes for women with a twin pregnancy that is reduced to a singleton pregnancy? summary answer: Fetal reduction of a twin pregnancy significantly improves gestational age at birth and neonatal birthweight, however at an increased risk of pregnancy loss and preterm delivery. what is known already: Women with a multiple pregnancy are at increased risk for preterm delivery. Fetal reduction can be considered in these women. study design, size, and duration: Retrospective cohort study of 118 women with a twin pregnancy reduced to a singleton pregnancy between 2000 and 2010. participants/materials, setting, and methods: We compared the outcome of pregnancy in consecutive women with a dichorionic twin pregnancy that was reduced to a singleton pregnancy to that of women with a dichorionic twin pregnancy that was managed expectantly and women with a primary singleton pregnancy. Reductions were performed between 10-23(6/7) weeks' gestation by intracardiac or intrathoracic injection of potassium chloride, mostly for congenital anomalies. We compared median gestational age, pregnancy loss
