Impact of reverse end‐diastolic flow velocity in umbilical artery on pregnancy outcome after the 28th gestational week

Abstract

REDFV on DUAV represents an ominous and severe fetal condition with an adverse pregnancy outcome, especially in conditions associated with preeclampsia and/or intrauterine growth retardation. Intensive and frequent surveillance and aggressive management at the appropriate time would improve perinatal outcome.

“…The use of Doppler technique in obstetrics for evaluation of fetal well‐being is now generally accepted as an important clinical tool in the decision‐making, mainly in high‐risk pregnancies (1–3). To understand the physical characteristics of the blood flow velocity waveform (FVW) in the umbilical arteries, knowledge of their anatomy is important.…”
