“…It has been suggested that umbilical artery flow velocity waveforms might be used to screen unselected pregnant women for placental insufficiency (Redman 1989). Many reports have shown abnormal blood flow velocities to be a good predictor of adverse perinatal outcome in the high risk fetus, both in pregnancies complicated by intrauterine growth retardation (Erskine & Ritchie 1985;Burke et al 1990;Hackett et al 1987) and maternal hypertension (Trudinger & Cook 1990;Cameron et al 1988). We have found no reports of prediction of outcome beyond the perinatal period.…”

Objective To determine whether the predictive value of Doppler ultrasonography extends beyond the perinatal period. Design Descriptive follow‐up study. Setting Specially designated paediatric clinic in Royal Maternity Hospital Subjects 40 children who as high risk fetuses had had assessment of umbilical artery flow velocity waveforms. Interventions Parental history, physical examination, anthropometry, Denver developmental screening test. Outcome measures Weight, height, head circumference, neurological impairment, Denver developmental screening test Result Abnormal waveforms were an accurate predictor of neonatal outcome, with significant differences in birthweight, gestational age, need for nursery admission, and frequency of intrauterine growth retardation between normal and abnormal waveform groups. However, abnormal Doppler studies were not predictive of long‐term adverse sequelae. There were no significant differences in height, head circumference, proportion with neurological impairment, or results of Denver developmental screening test at a median age of five years. Conclusion The predictive value of Doppler ultrasonography is less for long‐term growth and neurodevelopment than for perinatal outcome in the high risk fetus.

“…The benefi t of Doppler umbilical artery blood fl ow monitoring as a tool for the antenatal assessment of the fetal well-being in high-risk pregnancies has been established in several trials [6,15,16,33] . Various reviews, metaanalyses, and randomized studies have indicated that the use of Doppler sonography of the umbilical arteries in growth-restricted fetuses was associated with a statistically signifi cant improvement in perinatal outcome and an approximately 38 % reduction in perinatal mortality [1,2,26] .…”

“…In the present study we used 2 indices: S/D ratio and Pulsatility index. S/D ratio 95th percentile in high risk pregnancy was given as 3 at 34 weeks by Cameron et al 8 Using these cut-offs, 25% of high risk cases and 5% of the controls had an abnormal S/D ratio at 34 weeks. Similarly, Dubey et al 14 found an abnormal umbilical artery S/D in 29.2% of high risk cases.…”
