Outcome of early-onset fetal growth restriction with or without abnormal umbilical artery Doppler flow

Introduction: Early-onset fetal growth restriction is a pregnancy complication often coinciding with abnormal Doppler flow in the umbilical artery. Absent or reversed end-diastolic flow in the umbilical artery is associated with adverse perinatal outcome. As the optimal management of this condition is unclear, the objective of this study was to analyze the time interval from admission to delivery of pregnancies with early-onset fetal growth restriction, while pursuing a policy of postponing delivery unless active management of labor would be required because of fetal distress or maternal condition. We also assessed short- and long-term perinatal outcome. Material and methods: In this historical cohort study, all pregnant women with singleton pregnancies, admitted during 2004–2015 with early-onset fetal growth restriction were included. Pregnancies with absent or reversed end-diastolic flow (AREDF) were compared with pregnancies with a positive end-diastolic Doppler flow (PEDF). Time until delivery was deter
