Clinical significance of intermittently absent end-diastolic flow of the fetal umbilical artery on perinatal and neonatal outcomes

This study highlights an important prognostic distinction between intermittently absent end-diastolic umbilical artery Doppler flow and persistently absent flow, with intermittently absent end-diastolic umbilical artery Doppler flow representing a less severe form of placental insufficiency. These findings provide valuable insights for optimizing antenatal surveillance strategies, suggesting that intermittently absent end-diastolic umbilical artery Doppler flow cases may be candidates for outpatient management, whereas persistently absent flow cases require more intensive monitoring.
