[Doppler ultrasound flow measurement of fetal and uteroplacental blood vessels. Study of a normal population in the 2d half of pregnancy].
Weekly Dopplersonography measurements were performed on the fetal aorta abdominalis, the umbilical artery, the fetal carotid artery and the uterine arcuate artery from the 20th to the 41st weeks of gestation, mean and maximum blood flow velocities were measured, as well as the resistance index. The mean values calculated from 20 cases per week were translated into standard graphical representations serving as a criterion for the assessment of pathological pregnancies. The vessels were examined as to their value for a screening programme of fetal circulation. A sample curve of a severe placental insufficiency showed significant deviations from the standard curves.
