The specific features of management in the first trimester of pregnancy after in-vitro fertilization

The course of pregnancy was retrospectively analyzed in 105 women after in-vitro fertilization. In this group, approximately one half of the pregnant women were found to develop fetoplacental insufficiency and fetal growth retardation in late periods. In this connection, 22 women underwent ultrasonography for the development of early diagnostic and predictive criteria for primary fetoplacental insufficiency. The determination of chorionic volumes, vascularization index, and blood flow index was proposed to adjust the administered dose of progesterone. This examination and treatment method could reduce the frequency of complications and early reproductive losses by 2-2.5 times.
