Doppler indices of uteroplacental-fetal blood flow in pregnancies complicated by preeclampsia

In the study “case - control” there were 44 pregnant women - 14 women whose pregnancy was not complicated by preeclampsia, 16 pregnant women with mild preeclampsia, 14 patients with severe preeclampsia; we analyzed the course of pregnancy and birth outcomes, the dynamics of doppler indicators. It was determined that in the second trimester of pregnancy with preeclampsia, especially with severe one, the frequency of impairments of uterine blood flow is much higher. Sub- and decompensated chronic placental insufficiency, syndrome of fetal growth retardation were often revealed in the third trimester of gestation with preeclampsia, the severity of symptoms was most pronounced in severe preeclampsia. The reliable higher Doppler parameters in the “mother - placenta - fetus - system” were recorded in severe preeclampsia in the second and third trimesters. Thus, the results of evaluation of the uteroplacental blood flow can be used as the predictors of preeclampsia in the second trimester and as the markers of the severity of preeclampsia in the third trimester.
