For the first time, a scoring scale has been developed to determine the degree of cardiac dysfunction in congenital heart defects using Doppler ultrasonography of the pulmonary artery and vein, ejection fraction and stroke volume of the ventricles of the fetal heart in the prenatal period;
Evaluation of ventricular EF. a) ventricular ESV; b) ventricular EDV;
When using color Doppler imaging, both the pulmonary vein and the pulmonary artery are included in the control volume. Doppler spectrum of blood flow in the pulmonary artery (above the baseline) and pulmonary vein (below the baseline). 1 - atrioventricular valve closure point, 2 - pulmonary valve opening point, 3 - pulmonary valve closure point, 4 - atrioventricular valve opening point, 5 - dicrotic notch, 6 - wave caused by vascular wall turgor. ET - ejection time, IVCT - isovolumetric contraction time, IVRT - isovolumetric relaxation time, ACT - atrial contraction time. For the first time, the presence of four types of anatomical variants of the fetal portal venous system structure has been proven based on ultrasound examination data - T-, X-, H-shaped types and in the form of trifurcation in the diagnosis of fetal venous system development anomalies;
Connection with the main portal vein and its branches a) T-shaped type I; b) X-shaped connection type II; c) H-shaped type III, the connecting vessel is indicated by an arrow, d) a variant in the form of a trifurcation. In the diagnostics of abnormal pulmonary venous return, new Dopplerographic signs have been proven, such as "connection of all four pulmonary veins at one point (X-shaped type of connection)" in the supracardiac type of TADPV and "a sign of the mutual arrangement of the descending vertical vein with the aorta and descending vein" in the infracardiac type;
Supracardial type of TADLV. a) section at the level of confluence of the pulmonary veins, sign "X"; b) cross-section at the level of the main vessels and vertical vein;
Infracardiac type of TADLV. a) relative position of the aorta and vertical vein in the sagittal section of the chest; b) relative position of the aorta, inferior vena cava and vertical vein in the abdominal cavity
In order to improve the timely and accurate diagnosis of congenital heart defects in the prenatal period, the protocol of extended fetal echocardiography has been improved using additional eleven heart sections and Doppler evaluation of intracardiac hemodynamics;
In women at risk, in order to reduce perinatal mortality and disability rates in children, ultrasound diagnostics of congenital heart defects in the prenatal period has been improved by using a scheme of triple screening ultrasound examination of the heart and extended fetal echocardiography.
The necessity of using ADF and B-Flow modes in patients with carotid artery atherosclerosis has been proven for a more accurate assessment of the degree of stenosis, the contour of the atherosclerotic plaque due to the absence of the flow dependence angle and the possibility of detecting low-speed flows;
Standard values of total cerebral blood flow by age groups have been developed to characterize the features of carotid atherosclerosis in the Uzbek population;
To improve the accuracy of assessing the volumetric cerebral blood flow in carotid artery atherosclerosis, a regression model has been developed using the cerebrovascular reserve index;
It has been proven that a decrease in the cerebrovascular reserve index below 0.8 according to ultrasound Dopplerography in patients with a stenosis degree above 50% is a sign of hemodynamically significant arterial damage associated with a decrease in the volume of cerebral blood flow.
Right ICA, flow volume 360 ml/min - Left ICA, flow volume 210 ml/min.
Right ECA, flow volume 120 ml/min - Left ECA, flow volume 150 ml/min.
Right PA, flow volume 40 ml/min - Left PA, flow volume 40 ml/min.
Example of assessment of the CBC in an asymptomatic 67-year-old patient with significant stenosis of the right ICA (60%) with values of volumetric cerebral blood flow within the reference values (920 ml).
