THE COURSE AND OUTCOME OF PREGNANCY IN RECURRENT RETROCHORIAL HEMATOMA

The problem of miscarriage and preterm pregnancy does not lose its relevance. Symptoms of a threatened miscarriage develop in 25% of pregnant women, i.e. in almost every four pregnant women, while in 13.0-16.7%, they are accompanied by the formation of retrochorial hematomas (RCH) that, in turn, lead to disturbances in the normal processes of implantation, trophoblastic in-vasion, and the formation of a uteroplacental hemodynamic compartment. The aim of the investi-gation was to study the characteristics of the course of pregnancy and the outcomes of labor when detecting various RCH volumes at 6-26 weeks’ gestation. Recurrent RCH (retromembranous, in-termembranous, retroplacental) is a serious complication of pregnancy. Unlike the hematoma de-tected only in the early pregnancy stages (less than 10 weeks’ gestation), recurrent uteroplacental hemorrhages substantially disrupt placentation processes, causing a considerable increase in the risk of early preterm delivery [OR = 9.344; 95% C11.180-73.976], placental insufficiency [OR = 5.625; 95% CI 2.452-12.906], including decompensated, ante- and intrapartum losses [RR = 1.825; 95% C11.596-2.086].
