[Doppler study of the fetal and uteroplacental blood flows in IUGR].

It was established during Doppler examination of the fetal and uteroplacental blood flow in intrauterine retardation in the growth of the fetus (IUGR) that the mean velocity of blood flow in the fetal aorta was 29.21 +/- 3.98 sm/s. It was statistically significantly lower than that in normal pregnancy. The mean velocity of the blood flow in the umbilical artery--30.90 +/- 5.82 cm/s and in the artery--54.22 +/- 15.48 cm/s were also lower than those in normal pregnancy, but the difference was not statistically significant. It is pointed out that the lack of terminal diastolic blood flow of the fetal aorta and the presence of double incisure of the artery arcuatus are pathological signs of Doppler wave. It is indicated the Doppler examination of the fetal and uteroplacental blood flow in IUGR is a new noninvasive method for early diagnosis of placental insufficiency.
