Prognosis for fetuses with isolated severe growth retardation from 23 gestational weeks with an initial assessment unfavorable to an active management.

Objective: To study perinatal outcomes for newborns with early, isolated, severe FGR, for whom initial active management was considered unreasonable or impossible at an obstetric-pediatric assessment and to identify the determinants associated with a course that made active management reasonable.

Material And Methods: This retrospective observational single-center study occurred in a level-3 university hospital maternity unit. It included all pregnancies with a singleton fetus presenting isolated FGR <3rd percentile at 23 weeks or more of gestation with an obstetric-pediatric assessment (OPA) initially unfavorable to active management.
