Objective: This study aimed to estimate the risk of adverse perinatal outcomes among pregnant patients with intermittently absent (iAEDF) and persistently absent end-diastolic umbilical artery flow (pAEDF). The fetal risks associated with persistently absent end-diastolic flow have been described. However, the risks associated with intermittent absent end-diastolic flow are not well-known. Study design: We performed a retrospective cohort study of patients diagnosed with the iAEDF or pAEDF at our institution from 2020 to 2023. Fetuses were classified under two categories: iAEDF group and pAEDF group.Neonatal outcomes, demographic information, pregnancy outcomes and pregnancy complications were compared between patients with iAEDF and those with pAEDF.
