Describe perinatal outcomes in pregnancies with FGR stage 1 and to evaluate the potential impact of route of delivery. This was a retrospective cohort in pregnancies with stage 1 FGR, who had an ultrasound Doppler 15 days before delivery, with a confirmed birthweight below the 10 centile and normal or abnormal Doppler parameters, the presence of abnormal Doppler was not considered to define mode of delivery. A total of 642 pregnancies full field the inclusion criteria. Among patients included, 298 (46.4%) were delivered vaginally and 344 (53.6%) by Caesarean section. The rate of perinatal asphyxia was 0.9%, there were two neonatal deaths, and only one of these deaths was considered could be related to FGR. No statistically significant differences were found between route of delivery and the frequency of adverse perinatal outcomes (all p values > 0.05). Furthermore, none of the criteria used to identify FGR stage 1, have an influence in perinatal outcomes, regardless of the mode of delivery. Vaginal delivery was identified as a protective factor in the case of admission to the NICU and need for supplemental oxygen. Pregnancies complicated with FGR stage 1 can be safely managed with expectant management until term, and Doppler abnormalities do not have an impact in perinatal outcomes irrespective of the route of delivery. There was not enough information to explore the association between asphyxia and perinatal death given the small number of cases, however, the perinatal death rate is markedly lower than that reported in the literature.
