We studied the relationship between the degree of increase in RI with pre-eclampsia and the presence or absence of dicrotic the notch in the uterine arteries. A dopplerometric study was performed in both uterine arteries of all patients. We divided the patients of this group (89 pregnant women) into three subgroups according to the level of resistance index (RI) - the most informative indicator of blood flow disturbance: 1st subgroup - 0.48-0.60 (27 pregnant women), 2nd subgroup - 0,61-0,70 (33 patients), 3rd subgroup - 0,71-0,98 (29 pregnant women). It was found that the increase in RI within 0.48-0.60 in the majority of patients (85.2%) was combined with the presence of a dicrotic notch in both uterine arteries; an increase in RI was accompanied by the presence of a dicrotic notch only in one of the uterine arteries within 0.61-0.70 in 72.7% of pregnant women with preeclampsia.

The analysis of the obtained data allowed us to establish prognostic dopplerometric markers of severe preeclampsia: an increase in the RI up to 0.60 and the presence of a dicrotic notch in both uterine arteries, or an increase in RI within 061- 0.70 in the presence of a dicrotic notch only in one of the uterine arteries, and an increase in the RI of more than 0.70 in the absence of the dicrotic notch in the uterine arteries. The determination of these parameters of dopplerometry from the first and second trimester of pregnancy can serve as an early prognostic and preclinical preeclampsia test.
