Web4 May 2024 · The umbilical artery (UA) Doppler pulsatility index is used clinically to detect elevated feto-placental vascular resistance. However, this metric is confounded by variation in fetal cardiac function and is only moderately predictive of placental pathology. WebThe purpose of this study is to assess perinatal outcome in patients showing absent end-diastolic velocity (AEDV) and reversed end-diastolic velocity (REDV) in umbilical artery flow velocity waveforms. We reviewed our experience of patients showing AEDV and REDV in the umbilical artery flow velocity waveforms over nineteen months.
