<p>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 determined and perinatal outcome was assessed for both groups. Results: In our study, 111 women were allocated to the PEDF group and 109 to the AREDF group. In the AREDF group, fetal distress was more often an indication for delivery, in comparison with the PEDF group (p =.004). Median time until delivery in patients admitted between 26 and 28 weeks’ gestation was 6+5 weeks in the PEDF group and 1+4 weeks in the AREDF group (p =.001). No statistically significant difference was found between the Doppler groups in the composite adverse neonatal outcome, which includes at least one of the following outcomes: infant respiratory distress syndrome, sepsis, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage &gt;grade 2, periventricular leukomalacia and perinatal death (p =.63). Conclusions: In this study, comprising pregnancies with early-onset fetal growth restriction, fetal distress was observed more frequently in the AREDF group with the consequence of delivery at an earlier stage of gestation, compared with the PEDF group. AREDF was not associated with increased perinatal morbidity and mortality compared with PEDF.</p>
