Placental insufficiency may be one of the causes of early preterm birth. Its timely diagnosis can determine the measures of prediction and prevention of birth of children withextremely low body weight. The aim of our study was the comparative evaluation of indicators fetometry of the fetus, the parameters of uterine-placental blood fl ow and the level of human chorionic gonadotropin in the second trimester of gestation in the group of women with realised preterm deliveries at 22 to 27 weeks and the group of women who gave birth at term.

Taken for comparing the control group, which included 50 women with uncomplicated pregnancy and delivery in time. When carrying out statistical processing of the results of the study and control groups it was revealed that human chorionic gonadotropin in the first group is lower than in the second one. Th is indicator (in the study at 16-18 weeks of gestation) was in the first group 26022 (22389-47949), in the second group — 51200 (42800-83380) with a statistical significance of p=0.02. Statistical processing of the results of the second ultrasound screening of the fetus also showed that in the first group (n=79) reduced growth of the fetus and the increase of the resistance index in uterine-placental vessels were observed in comparison with the second group ( n=50), where women delivered at term.
