2023年5月8日 · Absent end-diastolic flow (AEDF) in an umbilical artery Doppler assessment is a useful feature that indicates underlying fetal vascular stress if detected in mid or late pregnancy. It is often classified as Class II in severity in abnormal umbilical arterial Dopplers 9.

Umbilical artery Doppler (UAD) velocimetry is utilized to assess fetal status in fetal growth restriction (FGR). Absent end-diastolic flow (AEDF) is indicative of increased placental resistance and is associated with poor fetal/neonatal outcomes.

REDF and AEDF are associated with significant uteroplacental insufficiency and an 80-fold increase in perinatal mortality. 8 The risk of stillbirth is 6.8% and 19% with AEDF and REDF, respectively. 4 Early-term delivery (37 weeks) is recommended for FGR pregnancies with elevated UAD PI or severe FGR with EFW less than the third percentile with ...

2012年1月11日 · Intrauterine growth restriction (IUGR) is defined as sonographic estimated fetal weight <10th percentile for gestational age. 1 According to the American College of Obstetricians and Gynecologists, IUGR is “one the most common and complex problems in modern obstetrics.” 2 This characterization is understandable considering the various ...

Intrauterine growth restriction (IUGR) Will be used to describe a pathologically small fetus (ie EFW<10 th centile, oligohydramnios, abnormal UA Doppler AND/ OR poor interval growth velocity

2006年5月1日 · Objective: Absent or reverse end-diastolic flow (Doppler II/III) in umbilical artery is correlated with poor perinatal outcome, particularly in intrauterine growth restricted (IUGR) fetuses. The optimal timing of delivery is still controversial.

2007年6月22日 · Fetuses with persistently absent or reversed end-diastolic flow (AREDF) in the UA have been reported to have a high risk of hypoxic deterioration and consequently intrauterine demise 3, 6, 18.

2014年2月11日 · The Prospective Observational Trial to Optimize Paediatric Health in IUGR (PORTO) Study recruited 1,200 ultrasound-dated singleton IUGR pregnancies, defined as EFW <10 th centile, between 24 +0 and 36 +6 weeks gestation. All recruited fetuses underwent serial sonographic assessment of fetal weight and multi-vessel Doppler studies until birth.

2005年6月22日 · Absent end-diastolic flow (AEDF) in the monochorionic intrauterine growth-restricted subgroup without twin–twin transfusion syndrome (TTTS) (MC non-TTTS) has a longer latency, compared to dichorionic (DC) and singleton (S) pregnancies with AEDF.

We retrospectively studied the outcome of pregnancy in 62 cases of absent end diastolic flow (AEDF) of um- bilical artery Doppler flow velocity waveform. Measure- ments were carried out using a sectorial 3.5MHz (ATL Ultramark 4) pulsed-wave Doppler with spectrum analyser.
