Research objective: to evaluate the effectiveness of diagnosis and complex therapy of placental dysfunction (PD) in early stages of gestation.Materials and methods. We examined 110 pregnant women with risk for the primary PD. Exclusion criteria were multiple pregnancies, anomalies of fetal development and internal genital organs of the mother, pregnancy resulting from assisted reproductive technologies.The diagnosis of PD was established in 56 women (group I) based on the assessing the state of extraembryonic structures and blood flow in the spiral and uterine arteries at 12–13 weeks of gestation. The rest of the patients (54 women) entered the control group without PD (group II).Results. All pregnant women with verified PD at 12–13 weeks were prescribed complex drug treatment, which included micronized progesterone, venotonic Normoven, Magnicum, and Artihol. As a result of treatment, already at 22–24 weeks of gestation, the average value of blood flow (resistance index) in the uterine and spiral arteries did not differ significantly in the groups. There was no significant difference in fetometry and placentometry indices at 35–36 weeks of gestation. Complications of the gestational period in patients in the study groups were also almost the same.Conclusions. History of hormonal disorders and miscarriage, clinical signs of miscarriage in early gestation, abnormal embryo placement, extragenital pathology, and genital tract infections are risk factors for PD. Determination of the state of extraembryonic structures at 7–8 weeks of pregnancy (ovum volume, blood flow in the corpus luteum) and at 12–13 weeks (chorion volume, vascularization index, blood flow in the spiral and uterine arteries) can serve as a verification criterion for the PD development. Complex drug therapy, which began from the early stages of gestation (micronized progesterone, Normoven, Magnicum, Artihol) has established itself as an effective method of treating primary PD in pregnant of risk groups.

Research aim was to study the features of perinatal complications depending on the nature and timing of therapy in pregnant women with primary placental dysfunction.Materials and methods. 82 pregnant women with verified placental dysfunction (chorionic hypoplasia at 12–13 weeks) against the background of the threat of pregnancy termination and genital tract infections were included. All examined were divided into 2 groups: group I consisted of 42 pregnant women who started treatment before 16 weeks of gestation, group II consisted of 40 pregnant women whose treatment was started after 16 weeks of gestation. Women in group I received micronized progesterone, venotonic Normoven, Magnicum and Artihol. Antibacterial sanitation was carried out before 16 weeks of gestation. Group II also received micronized progesterone only. Antibacterial sanitation in this group was carried out after 16 weeks of gestation.Research results. After antibiotic therapy in group I monoinfections value decreased from 26.8 to 9.5%, mixed infections value decreased from 56.1 to 20.7%, while in group II the effectiveness of antibacterial therapy after 16 weeks was significantly lower. Statistically significant differences in weight, volume and area of the placenta in patients of studied groups were obtained. Assessing perinatal complications showed that the frequency of gestosis, premature birth, intrauterine growth retardation and intrauterine infection of the fetus were almost 2 times less frequent in group I than in group II.Conclusions. Placental dysfunction, which developed in the first trimester against the background of the threat of pregnancy termination and genital tract infections, is the basic pathology for complications of the perinatal period. A timely prescribed set of medical supplies, including micronized progesterone, venotonic Normoven, Artihol and Magnicum, was as an effective method of preventing perinatal complications in pregnant women with primary placental dysfunction. Antibiotic therapy up to 16 weeks of gestation does not fully prevent the development of perinatal complications, but it can significantly reduce the level of severe gestational pathology.

The objective: frequency decrease perinatal pathologies at women after ART on the basis of studying clinical-ehografical, endocrinological, biochemical, dopplerometrical, cardiotokografical and morphological researches, and also improvement of algorithm of diagnostic and treatment-and-prophylactic actions. Patients and methods. The work basis is made spent by us from 2012 on 2015 by complex inspection of 300 pregnant women from which 250 were after ART and 50 – firstlabours which pragnency without ART, and also their newborns. For the decision of an object in view of research spent to two stages. At 1 stage spent prosperctive research which included 150 pregnant women: з them 100 women pregnancy at which has come out ART (1 group) and 50 healthy women (control group). At 2 stage spent prospective randomization in which result of patients after ART have divided on two equal groups by therapy principle: 2 basic group - 75 pregnant women after ART at which used the algorithm improved by us; 3 group of comparison - 75 pregnant women after ART which have been spent on the standard treatment-and-prophylactic actions. Results. The results suggest that women after using ART is a high frequency of reproductive losses in the first trimester (10.0%), 3.0% of spontaneous abortion from 16 to 22 weeks, and 3.0% "early" premature delivery (22 to 28 weeks of pregnancy). The frequency of violations of the functional state of placenta in women after using IVF is 63.0%, which is the main cause of high levels of perinatal losses (40.0 ‰), and delivery by cesarean section (96.0%). Placental dysfunction in women after using ART characterized by retrohorialnyh hematoma (21.0%); size mismatch fruit (30.0%) and hypertonicity of the uterus (73.0%) against changes in fruit-placental blood flow - increased resistance index in umbilical artery and increased vascular resistance in the uterine arteries. Endocrinological and biochemical changes in placental dysfunction in women after using IVF starting from 28 weeks of pregnancy and are in significant reduction in progesterone, placental b1-microglobulin, B2-microglobulin of fertility and trophic в-glycoprotein. Conclusion. The received results: use of the algorithm of diagnostic and treatment-and-prophylactic actions improved by us allows to lower frequency of spontaneous interruption of pregnancy till 22 weeks – from 13.0% to 5.7%; «early» premature birth – from 3.0% to 1.0%; placentary dysfunction from 63.0% to 40.6%; cesarean sections – from 96.0% to 56.5%, and also perinatal losses – from 40.0‰ to 16.2‰. Key words: pregnancy, childbirth, auxiliary reproductive technologies.

Hypothesis/aims of study. Poor placental vascularization can lead to placental insufficiency, due to which the metabolism of nutrients and microelements between the maternal and fetal blood circulations subsequently decreases. Due to poor perfusion of placental vessels, placental dysfunction occurs. Chronic fetal hypoxia causes fetal growth retardation. The aim of this study was to assess the frequency of placental insufficiency in women with different somatotypes and to develop a model for predicting the risk of this pathology. Study design, materials and methods. A total of 390 women were examined, of whom 110 were macrosomatic, 173 mesosomatic, and 107 microsomatic. Somatometry was performed according to R.N. Dorokhov for women in the early stages of pregnancy (up to 9-10 weeks). Placental insufficiency markers (VEGF, PlGF, IL-6, and endocan-1) were determined spectrophotometrically in blood serum at the gestational age of 1213 and 2223 weeks using ELISA methods. Results. Placental insufficiency was significantly more prevalent among the women of the macro- and microsomatic body type compared with those of mesosomatotypes (p 0.05). In pregnant women with subsequent placental insufficiency, VEGF and PlGF serum levels at 1213 weeks were lower, when compared to those in patients who did not develop pathology (p 0.05), and the levels of serum endocan-1 and IL-6 were higher in comparison with those in individuals who did not develop pathology (p 0.05). Using multiple regression analysis, we obtained the regression equation (formula), which predicts the development of placental insufficiency in women of different somatotypes. Conclusion. The resulting formula allows us to accurately predict the development of placental insufficiency and to form high-risk groups among women for the development of this disease. This will contribute to the effective implementation of therapeutic and preventive measures to avert the development of this pathology.

We represent the results of the combined method of treatment and prevention of miscarriage in women with a multiple pregnancy and a high risk of the threat of termination the pregnancy because of using the obstetric unloading pessaries, combined with micronized progesterone. The efficiency of this method of treatment is evidenced by the rapid elimination of clinical symptoms of threatened abortion, accelerating the regression of ultrasound markers, reducing the number of complications in of pregnant women and reducing the time of their stay in hospital.Goal: To evaluate the effectiveness of the handling the obstetric pessary in combination with micronized progesterone at women with multifetal pregnancy and a high risk of miscarriage.Materials and methods. We analyzed 120 cases of multifetal pregnancies with signs of miscarriage within the terms from 16 to 28 weeks. The first group of the examined women was: 40 pregnant women with twins and signs of miscarriage, who in the scheme of treatment and prophylactic measures were offered to use the unloading obstetric pessaries in combination with continuous therapy by natural micronized progesterone until 36 weeks of pregnancy. The second group included 40 pregnant women with twins, who were laid seam on the cervix because of istmicocervical insufficiency and were applied short-term courses of therapy by gestagens. The control group comprised 40 pregnant women with twins at the age of 16-28 weeks of pregnancy who were conducted the therapy about the threat of miscarriage according to the current clinical protocols (Order of the Ministry of Health of Ukraine No. 624). It was carried out the analysis of the course of pregnancy, childbirth, the postpartum period and the state of neonatal adaptation in the surveyed groups.Results of the research and their discussion. In the first group, urgent childbirth occurred in 34 (85%) cases, in group II in 29 (72.5%) cases, in control group – in 25 (62.5%) cases. Cesarean delivery was performed in 7 (17.5%) patients of group I pregnant women, in 9 (22.5%) of group II patients and in 11 (27.5%) in the pregnant group. When studying the state of neonatal adaptation of newborns in the examined groups, the following results were obtained. The average weight of the newborns in group I was 3245 ±280 g, in group II 2865 ±365 g, in the control group - 2975 ±325 g (p>0.05). The evaluation of the state of newborns on the Apgar scale, respectively at the 1st and 5th minutes, was respectively: in newborns of the I group, 7.5 ± 1.4 and 8.4 ± 1.3 points, in group II - 7.3 ± 1.6 and 8.2 ± 1.1 points, in the control group – 7.2 ± 1.6 and 8.6 ± 1.2 (р 1-р 2> 0.05).Conclusions. Comprehensive prophylaxis of non-pregnancy in multiple pregnancies, combining the use of a traumatic cardiac cervix with the help of unloading obstetric pussies with progesterone preparations, allows prolonging pregnancy, preventing the development of prematurity, contributes to the improvement of perinatal indicators.

Placental Dysfunction

Background. Placental dysfunction (PD) is one of the most common complications of pregnancy, which has not only medical but also social significance. The links of the PD pathogenesis include endothelial dysfunction, hemodynamic disorders of the placental vessels, disorders of arterial and venous blood flow in the placenta. Objective. To study diagnostic methods and possibilities of PD correction in women with preeclampsia (PE). Materials and methods. The study involved 68 women with PE in the II and III trimesters of pregnancy, treated at the multidisciplinary clinic of the Tashkent Medical Academy during 2017-2019. Patients underwent standard clinical, laboratory and instrumental examination with color Doppler mapping of vessels of the uterine-placental-fetal system and ultrasound evaluation of the fetoplacental system. Results and discussion. Premature aging of the placenta was found in 77.3 % of cases, turbid amniotic fluid – in 59.09 %, oligohydramnion – in 27.3 %. Disorders of uteroplacental blood flow were detected in 28.3 % of cases, placentofetal blood flow – in 26.7 %. Impaired blood flow at both levels without critical values occurred in 10 % of pregnant women. In case of insufficiency of a blood circulation of 2nd grade the syndrome of fetal growth restriction was observed in 16,7 % of cases. Compensated forms of PD were subject to the comprehensive treatment with the addition of infusions of L-arginine (Tivortin, “Yuria-Pharm”) in the inpatient phase and oral administration of Tivortin aspartate in the outpatient phase. The length of the fetal thigh in the group of L-arginine at the beginning of treatment was 47.33 mm, which was by 9.04 % less than this parameter in physiological pregnancy. After treatment with Tivortin, in the full-term period, no significant difference was found. In pregnant women who received L-arginine at 25-29 weeks of pregnancy, after 2 weeks, the resistance indices (RI) of the umbilical artery and uterine artery decreased from 0.68±0.09 to 0.58±0.05 and from 0,58±0.16 to 0.43±0.08, respectively. The RI of the middle cerebral artery increased from 1.05±0.23 to 1.27±0.19. Parameters of RI dynamics indicate that the early treatment with Tivortin is more effective than late. Conclusions. 1. Regardless of the presence of fetal growth restriction syndrome in women with disorders of uterine-placental-fetal circulation, it is advisable to include L-arginine in the treatment to prevent this condition. 2. Ultrasound examination is a reliable method for evaluating the effectiveness of PD treatment.

Objective is to develop new methods to prevent primary placental dysfunction (PD) in early gestational age with low placentation.Material and methods. We have examined 119 pregnant women with low placentation. This diagnosis was made from 6-7 weeks of gestation on the basis of echographic research. The main group consisted of 64 pregnant women with low chorionic location, which was used to prevent PD from the early gestational age by the complex of medicines developed by us and a control group of 55 women with low placentation that had not undergone PD prophylaxis from early gestational periods. The treatment and prophylactic complex included: Luteina, ginkgo biloba extract, folio and biolectra. In the main and control groups, all pregnant women underwent Doppler examination in the uterine and spiral arteries, as well as determined the volume of the chorion and the volume of blood flow in the chorion.Results. Doppler examination in the main group showed a decrease in all indices of resistance in the uterine and spiral arteries, as well as a significant increase in chorionic volume and vascularization index in three-dimensional ultrasound compared with the control group.Conclusions. The proposed treatment and prophylactic complex agents (Luteina, ginkgo biloba extract, folio and biolectra) helps to normalize uterine-chorionic blood flow, restore effective embryo-chorionic relationships and significantly reduces the frequency of further development of primary placental dysfunction in pregnant women with low-grade pregnancy.

Objective of the research: conduct a Doppler ultrasound (DUS) assessment of utero-placentalfetal blood flow and the condition of newborns in the early neonatal period from women of the late reproductive period (LRP), depending on the parity of delivery, using the example of women in the Chechen Republic. Material and methods: retrospective multicenter study. DUS assessment of the state of utero-placental-fetal blood flow and the state of newborns in the early neonatal period was performed in 95 pregnant women, including: group 1–35 primiparous of LRP and their 35 newborns, group 2 – 35 multi-pregnant (MP) of LRP and their 35 newborns. The 3 control group included 25 healthy pregnant women aged 18 to 25 years and their 25 newborns. DUS was performed on Aloka SD SSD 3500 device (Japan), and a transvaginal sensor was used if necessary. Newborns were assessed on the APGAR score at 1 and 5 minutes after birth. Of the instrumental methods for examining newborns, brain ultrasound examination (neurosonography) was used. Results: analyzing the DUS results of LRP pregnant, depending on the labor parity, it was found that in the 1st group there was an increase in resistance in both uterine arteries (61%), an increase in the resistance index and pulsation index, a decrease in diastolic blood flow, characteristic of arteries with high resistance. Hemodynamic parameters in the mid-brain artery (MBA) of the fetus remained normal in all pregnant women. LRP women often born children in a state of asphyxia, with neurological disorders, and these children often has more complex postnatal adaptation and concomitant pathology. Among LRP women, primiparous has significantly more severe disorders. Conclusion: the data of uteroplacental fetal blood flow of the 1st group correspond to blood flow disorders of the IA degree, which indirectly indicates a compensatory reaction of the vascular system of uteroplacental fetal blood flow, as well as the absence of a tendency to an increase in the severity of fetoplacental insufficiency. It is possible that high incidence of neurological disorders in children born to LRP women is associated with age-related changes in their germ cells, use of assisted reproductive technologies, intake of hormonal drugs at an early stage of pregnancy and environmental factors associated with iodine deficiency in the region which includes the North Caucasus.

The dynamic increase in the number of caesarean section in Ukraine and around the world remains one of the main topics of discussion, which is intensively discussing by leading scientists. The traditional assessment of the ability of the uterus scar during pregnancy, based mainly on the analysis of clinical and anamnestic data, is not high informative, and the ambiguous conclusions of the sonographic study indicate the need for further detailed study. Therefore, there is reason to believe that the development of criteria for ultrasound assessment of the condition of the uterus scar after previous cesarean section will use them to predict the possibility of spontaneous delivery in the future and remains relevant. The objective: study the features of ultrasound diagnosis of the condition of the scar on the uterus in pregnant and non-pregnant women. Materials and methods. Observations and retrospective analysis of medical records of pregnant women and birth histories in 150 women with a scar on the uterus after a previous cesarean section for the period from 2014–2019. Results. In women who became pregnant up to a year after the previous cesarean section, the most pronounced changes in blood flow were in the uterine arteries, especially during gestation 28–34 weeks. Also, in women with a failed uterus scar, changes in blood flow were most often observed in the uterine arteries at all levels and were significantly higher, compared with women with a capable uterus scar and women from the control group. In women with an insolvent uterus scar, the most pronounced changes in the indices of vascular resistance was observed in the uterine arteries, in particular the right uterine artery. Conclusion. The peculiarities of blood flow and vascular resistance in different vessels of the myometrium depending on the gestation period and the timing of pregnancy after a previous cesarean section. The obtained detailed ultrasound examination and mathematical calculation of the results of ultrasound examination of the uterus and postoperative uterus scar after previous cesarean section in non-pregnant women allowed to create a scale for assessing the condition of the uterus scar after previous cesarean section in non-pregnant women. Keywords: cesarean section, uterus scar, ultrasound, pre-pregnancy preparation of women.

Doppler study is one of the main methods for assessing the condition of placental blood circulation and fetal hemodynamics. Doppler blood flow in the uterine arteries demonstrates the broad capabilities of the method for predicting pregnancy complications such as gestosis, fetal development delay, preterm birth, as well as for diagnosing adverse perinatal consequences. However, there is still no clear opinion about the feasibility of using Doppler as a screening test, as well as about the optimal pregnancy period for this type of study. The objective: is to study the hemodynamic features in pregnant women after assisted reproductive technologies (ART) application in the dynamics of the first part of pregnancy. Materials and methods. 299 pregnant women were examined – the main group included 249 women whose pregnancy occurred as a result of ART application. The control group consisted of 50 pregnant women with spontaneous pregnancy and its physiological course. I group – 94 women with tubal-peritoneal factor of infertility, II group – 87 women with endocrine factor of infertility, III group - 68 women whose infertility was caused by the male factor. Doppler ultrasound examination of the uterine arteries, arteries of the umbilical cord and middle cerebral arteries of the fetus were conducted. Results. It was found that the highest intensity of hemodynamics in the uterine artery basin at 11–12 weeks of gestation was recorded in a group of patients with a physiological course of pregnancy. The systolic-diastolic ratio in the right and left uterine arteries in these patients was 1.9 (1.8–2.7) and 2.1 (1.9–2.6), respectively. In contrast to women in the control group, pregnant women after ART application analyzed indicators were higher (1.6–1.9 times; p<0.0001). The systolic-diastolic ratio in the right uterine artery in III group was 3.0 (2.4–3.5), I group – 3.3 (3.1–3.4). Similar data were obtained analyzing the curves of blood flow rates in the left uterine artery – 2.9 (2.1–3.5) and 3.0 (2.7–3.6), respectively. The highest peripheral resistance, both in the right (3.6 (3.4–3.7) and left (3.5 (3.2–3.8) uterine arteries, was naturally registered in pregnant women of II group. In 36 (72%) patients with uncomplicated course and successful gestation at 11–12 weeks of pregnancy, blood flow was not recorded in the intervellon space. In the vast majority – 50 (73.5%) pregnant women of I group, two types of blood flow were registered in the intervellar space: pulsating arterial and continuous venous. Only in 18 (26.5%) patients of this group the blood flow in intervellon space was not determined. As a result of the obtained data analysis, it was found that at 16-17 weeks of gestation, the highest intensity of blood flow in the uterine artery pool was recorded in the control group. Thus, the systolic-diastolic ratio of the right and left uterine arteries in these subjects was 1.6 (1.5–1.8) and 1.8 (1.6–2.0). In pregnant women of the main group, the indicators were significantly higher (1.2-2.0 times; p<0.0001). The systolic-diastolic ratio in the uterine arteries in group III was 2,1 (1,9–2,6); 2,2 (1,9–2,5), in the II group – 3,1 (2,5–3,3); 2,2 (1,9–2,5), in the I group – 2,6 (2,5–3,2); 2,7 (2,5–2,9). In contrast to the control group, in which the systolic-diastolic ratio in the fetal umbilical artery was 3.4 (3.3–3.5), in III group patients, there was a significantly higher intensity of umbilical blood flow (S/D – 3.3 (3.5–3.6), p=0.03). At the same time, feto-placental hemodynamics in II and I groups patients was characterized by a significant increase in the numerical values of blood flow in the umbilical arteries (S/D – 4.5 (4.4–4.7), p=0.0001 and 3.5 (3.5–3.6), p=0.03, respectively). In patients of the control group, the systolic-diastolic ratio of the middle cerebral artery of the fetus at 16–17 weeks of gestation was 3.4 (3.4–3.5), almost completely coinciding with the same indicator in the umbilical artery (S/D – 3.4 (3.3–3.5). Patients of group III had a higher blood flow intensity, as evidenced by significantly lower (S/D 3.2 (3.1–3.3), compared with the control group (S/D 3.4 (3.4–3.5) absolute values of the systolic-diastolic ratio. An increase in the intensity of blood flow in the fetal medial artery (against the background of increased vascular resistance in the umbilical artery) was also recorded in the group of subjects of group II (S/D – 2.8 (2.7–2.9). High absolute values of systolic-diastolic ratio in the indicated vessel (4.4 (4.3–4.5) were found in the fetuses of the examined group and group, which characterize a significant decrease in the intensity of cerebral blood flow, compared with all the analyzed groups. Conclusions. Thus, the results of the study allow us to attribute Doppler ultrasound to highly informative research methods that make it possible to predict hemodynamic changes in the mother-placenta-fetus system, depending on the type of infertility, take preventive measures and start correction in time. Keywords: pregnancy, assisted reproductive technologies, Doppler ultrasound, uterine arteries, systolic-diastolic ratio.

Among the causes that lead to antenatal affliction of the fetus, namely its hypoxia, hypotrophy, ante- and intranatal distress, is placental dysfunction (PD). Perinatal mortality in PDs is 10.3‰ in newborn infants, 49 ‰ – in preterm infants. Perinatal morbidity with PD reaches 70‰, and mortality rate – 20%. Objective. To investigate the functional state of the fetoplacental complex (FPС) in pregnant women with PD. Material and methods. The functional status of the FPC in 104 patients with PD (main group) and in 136 women with uncomplicated pregnancy and delivery (control group) using ultrasound placentalography, Dopplerometry was examined. Research results. The ultrasound characteristics of the placental dysfunction were the following: discrepancy between the degree of maturity of the placenta of the gestation period, true thickening of the placenta, its hypoplasia, reduction of echogenicity of the placenta, oligohydramnios. Dopplerometric signs of disorder of the utero-placental blood flow were high peripheral vascular resistance, both in dominant and in subdominant UA, asymmetry of blood flow in UA. Hemodynamics of fetal-placental circulation against the ground of PD was characterized by a decrease in the final diastolic blood flow velocity, which was manifested by an increase resistance in the peripheral vascular of the fetal part of the placenta,  decrease in placental coefficient. The peculiarity of fetal blood flow in pregnant women with PD was the decrease in the mean value of vascular resistance indices in the middle cerebral artery of the fetus and a significant decrease in the cerebral-umbilical index. Conclusions. In pregnant women with placental dysfunction hemodynamic changes in the utero-placental complex are associated with decrease in the intensity of placental-fetal blood flow and in 16.3% of cases by centralization of the fetal circulation. Timely Dopplerometry is important both in the diagnosis of the compensatory capabilities of the FPK, and during determination of reasonable suggested obstetrical tactics.
