The objective: the study of the status of the embryo and extraembryonic structures for bleeding that is not associated with the detachment of the chorion in the first trimester of gestation. Patients and methods. Were examined 34 patients in the gestational age 6-9 weeks (main group) with bleeding from the genital tract, in which, at the primary ultrasonic inspection revealed no detachment of the chorion. The control group included 30 women with uncomplicated course And trimester of gestation. The average age of the pregnant women of the main group was 25.3±3.1 years in the control group 26.4±4.3 years. All women underwent standard clinical and laboratory examination. Results. Studies have shown that prognostic markers of unfavorable development of the embryo in the early stages of pregnancy bleeding not related to chorion detachment was not detected. For the purpose of hemostasis in pregnant of the main group of prescribed drugs traneksamic acid 0.25 mg 3-4 times a day for 3 days. Traneksam – antifbrinolytic tool is able to block not only plasminogen, and plasmin that has already formed. It also stimulates the synthesis of collagen, through which increases the elasticity of the fibrin clot. Pregnant women in both groups received vitamin E 1 capsule per day magnesium products, Magnicum 1 tablet 3 times a day, folic acid 400 micrograms per day. Assessing clinical signs of disease in dynamics of treatment, it should be noted that the hemostasis in the main group was achieved in an average of 2.3±0.7 days. Conclusion. Bleeding in early gestation, not connected with the detachment of the chorion, the use of Traneksam provides fast absolute hemostasis, which in turn contributes to the normalization of tone of the uterus and the physiological course of placentation. Key words: bleeding in early pregnancy, the chorion detachment, hemostasis, hemostatic therapy, Traneksam.

In women with miscarriage in early pregnancy by ultrasound was studied the volume of the ovum, the volume of the cavity of the amnion and their relationship. Using special three-dimensional VOCAL program performed the calculation of the volume of the chorion, the evaluation of his vascular system based on the definition of the vascularization index (VI) and flow index (FI). The aim of the study: to study the stages of growth and vascularization of the chorion with the threat of miscarriage in the first trimester of gestation. Materials and methods. There were examined 50 pregnant women with threat of miscarriage at early terms of gestation: 30 - burdened obstetric history (BOH), receiving the drug micronized progesterone 50 mg 3-4 times per day (the main group) and 20 pregnant women, the history of which was not encumbered, who were on symptomatic therapy (control group). Results. Analysis of the frequency of occurrence of extragenital pathology in the study groups showed that in women with recurrent pregnancy loss and BOH somatic diseases were almost 2 times more often than in the control group (respectively 60% and 30%). The frequency of infectious complications in the first trimester of pregnancy in women with threatened abortion and BOH compared to the control group of patients, significantly more frequently noted violations of vaginal microbiocenosis, in the form of gardnerellosis (20% and 10%), Candida vaginitis (30% and 5.5%) and urogenital infections – chlamydia, ureaplasmosis, mycoplasmosis (15% and 0%). All pregnant women was carried out sanitation of the source of infection in the first trimester of gestation – local therapy, systemic treatment after completion of the processes of placentation. Conclusion. The study found that use of micronized progesterone in miscarriage in the first trimester of gestation contributes to the growth of the volume of the chorion, the intensity of the flow in the parenchyma and a complete restructuring of the spiral arteries resulting in inadequate formation of the placental-uterine blood flow, which certainly improves the prediction of the further course of pregnancy. Key words: miscarriage, the I trimester of gestation, the vessels of the chorion.
