FEATURES OF THE COURSE OF MULTIPLE PREGNANCY AGAINST THE BACKGROUND OF FETAL GROWTH RETARDATION

Abstract

In most European countries in recent years, the frequency of multiple births ranges from 11 to 14 per 1000. These pregnancies have a high number of complications. Perinatal mortality in multiple births is more than 6 times higher than in singleton pregnancies. Severe neurological abnormalities under the age of 1 year have from 10% to 25% of twins. According to most researchers, the main cause of perinatal losses in multiple births is deep prematurity and severe fetal growth delay. It has now been proven that placental insufficiency is the main reason of developmental delay, discordant fetal growth, antenatal death of one of the fetuses. A fetus that develops and is born in conditions of chronic placental insufficiency is more vulnerable and at high risk of developing perinatal pathology. The purpose of the research was to study the frequency and structure of complications of the pregnancy and labor of women with multiple pregnancies, complicated uteroplacental insufficiency and fetal discordance. The study was carried out at the city clinical maternity house during 2013–2019. The information was gathered from literature and by interviewing pregnant women with twins. 20 pregnant women (group I) with dichorionic, diamnionic twins with the presence of placental insufficiency and fetal discordance of more than 20%. Group II consisted of 20 pregnant women with twins but fetal discordance did not exceed 20%. However, the control group ІІІ consisted of 30 women without complications and ended in physiological labor. The general, somatic, obstetric and gynecological anamnesis, especially the course of pregnancy, childbirth, the state of the cervix by vaginal and ultrasound examination were studied. The results of the study show that in the anamnesis of pregnant women with fetal discordance, take place in vitro fertilization and infections of the respiratory and urinary tract. Multiple pregnancies which were accompanied by fetal discordance exceeding 20% ​​is accompanied by impaired uteroplacental circulation. Labor with twins complicated by impaired uteroplacental circulation occurs in a large number of complications. The results can be applied to the using various medications for the correction of disorders of the uteroplacental circulation.
