[Doppler sonography of the umbilical artery: differential diagnosis in intrauterine growth retardation].
50 fetuses with IUGR were differenciated by pulsed Doppler-wave velocimetry of an umbilical artery. All cases with a normal A/B-ratio according to Stuart had spontaneous vaginal delivery and normal fetal outcome. Pathological flow velocity waveforms led to early delivery and a significantly high rate of cesarean section for fetal asphyxia and to a poor fetal outcome. The umbilical artery flow velocity waveform showed a high sensitivity and specificity with regard to fetal risk and indicated the latter earlier than the oxytocin challenge test. A positive correlation between elevated umbilical placental resistance and histomorphological disorders of the fetal placenta was found. Screening for fetal perinatal risk by means of pulsed Doppler ultrasound of the umbilical arteries is discussed in cases of IUGR.
