The objective: study of the anatomical and functional status of the uterus and ovaries in poor responders in ART programs. Materials and methods. Determination of the anatomical features and functional status of the uterus and ovaries in «poor responders» to exclude a clinically significant pathology that would affect the success of the ART program was performed by ultrasound scanning with the study of topografts, sizes, contours, echostructure of the uterus and ovary and determination of the volume of the ovaries and the number of antral follicles. Blood flow in the vessels of the stroma of the ovaries, as one of the important criteria for assessing the possible ovarian response, was assessed using color Doppler mapping. Results. «Poor responders» patients have a smaller sise of ovaries and a reduced number of antral folicles, which can be explained by the surgical interventions carried out according to the type of ovarian resection and the cysts removal. In addition, during the transition from the follicular to luteal phase, there is no decrease in the vascular resistance of the dominant follicle, which slows the process of ovulation and reduces the likelihood of fertilization in conditions of increased vascular resistance. Conclusion. Ultrasound examination of the uterus and ovaries and doplerometric investigation of peryfollicular blood flow allows us to thoroughly approach both the evaluation of the ovarian response and the endometric readiness for implantation, which dictates the need for an individual selection of preconceptional preparation and treatment programs for ART. Key words: anatomical and functional state, pelvic organs, ovarian reserve, peryfollicular blood flow, poor responders.

The article presents the results of color Doppler ultrasonography of the left renal vein and gonadal vein with the determination of the peak systolic velocity of blood flow and abnormal blood reflux in patients with left-sided varicocele. The objective of the research was to compare preoperative ultrasound characteristics of the left renal vein, left gonadal vein, peak systolic velocity of blood flow and the presence of abnormal blood reflux, the formation of ultrasound criteria for the selection of patients for surgical correction of phlebohypertension. Results. Ultrasound signs of aorta mesenteric compression were absent in 24 (24.5%) patients; the signs of aorta mesenteric compression without critical left renal vein stenosis were observed in 64 (65.3%) patients; critical stenosis of the left renal vein was diagnosed in 10 (10.2 %) patients. The patients with critical stenosis of the left renal vein underwent left renal vein transposition. Conclusions. Ivanissevich surgery with prognostically low risk of relapse is recommended for the patients with left-sided varicocele without any signs of aorta mesenteric compression. Patients with the signs of aorta mesenteric compression require clear determination of the degree of left renal vein stenosis. We consider the transposition of the left renal vein to be indicated in case of critical stenosis when the correlation of the diameters of the distal and proximal segments of the left renal vein is ≥ 3 and the ratio of peak systolic velocities in the proximal and distal segments is ≥ 6. Thus, the diagnosis of phleborenohypertension in the patients with varicocele by means of color Doppler ultrasonography with the determination of blood flow velocity indicators in the left renal vein circulation and the determination of the critical stenosis of the left renal vein is decisive in choosing the surgical method of treatment. This provides an opportunity to evaluate the cause of varicocele occurrence and choose the optimal method of surgical treatment.

Regional Vascular Resistance

The aim of the study: Combined use of kineso- and laser therapy to correct regional hemodynamic disorders in patients with dilated cardiomyopathy (DCMP). Material and methods: The study included 100 patients diagnosed with DCMP. The diagnosis "DCMP" was established for patients with dilatation of the heart cavity of non-coronatural origin, increased heart size (final diastolic size of the left ventricle - LV CDR > 6.0 cm). The determination of the CHF FC was made according to the Russian National Recommendations of the RSCS (2018) and OSSN on the diagnosis and treatment of CHF. All patients took differentiated medication-assisted therapy according to indications during 3 months. Patients were divided into 2 comparable groups by sex, age, disease course, severity of the condition, and specifics of medication therapy. Patients of the 1st group were treated with intravenous laser irradiation of blood (ILIB) and selection of unloading therapeutic gymnastics against the background of supporting differentiated medication therapy. Patients of the 2nd group (control) received only differentiated medication therapy. The main method of investigation was venous occlusal plethysmography to evaluate regional hemodynamics with the determination of blood flow (Qr) and regional vascular resistance (Rr) at rest, venous tone (Vt), reserve blood flow (QH) and regional vascular resistance (RH) on the background of a functional load test. РResults: The data obtained during the dynamic observation (in 1, 3, 6 and 12 months) in the main group showed a reliable increase in the volume velocity of the blood flow at rest (Qr) and the reserve blood flow (QH), a decrease in the regional vascular resistance at rest (Rr) and under functional load (RH), venous tone (Vt), respectively. In the control group there was no reliable positive dynamics, after 12 months of observation indicators of regional hemodynamics significantly deteriorated. Conclusion: In patients with DCMP, according to venous occlusal plethysmography, the use of relieving therapeutic gymnastics in combination with ILIB on the background of medication therapy has significantly improved the indices of regional hemodynamics. The developed method of non-drug therapy can be used by cardiologists, general practitioners, therapists, doctors of physical and rehabilitation medicine to optimize treatment of patients with DCMP.

Blood Flow Imaging

Abstract Objective: The objective of this study was to investigate the clinical applicability of navigated blood flow imaging (BFI) in neurovascular applications. BFI is a new 2-dimensional ultrasound modality that offers angle-independent visualization of flow. When integrated with 3-dimensional (3D) navigation technology, BFI can be considered as a first step toward the ideal tool for surgical needs: a real-time, high-resolution, 3D visualization that properly portrays both vessel geometry and flow direction. Methods: A 3D model of the vascular tree was extracted from preoperative magnetic resonance angiographic data and used as a reference for intraoperative any-plane guided ultrasound acquisitions. A high-end ultrasound scanner was interconnected, and synchronized recordings of BFI and 3D navigation scenes were acquired. The potential of BFI as an intraoperative tool for flow visualization was evaluated in 3 cerebral aneurysms and 3 arteriovenous malformations. Results: The neurovascular flow direction was properly visualized in all cases using BFI. Navigation technology allowed for identification of the vessels of interest, despite the presence of brain shift. The surgeon found BFI to be very intuitive compared with conventional color Doppler methods. BFI allowed for quality control of sufficient flow in all distal arteries during aneurysm surgery and made it easier to discern between feeding arteries and draining veins during surgery for arteriovenous malformations. Conclusion: BFI seems to be a promising modality for neurovascular flow visualization that may provide the neurosurgeon with a valuable tool for safer surgical interventions. However, further work is needed to establish the clinical usefulness of the proposed imaging setup.

Color Doppler imaging (CDI) can be used to noninvasively create images of human blood vessels and quantitatively evaluate blood flow in real-time. The purpose of this study was to assess the effects of acupuncture on the blood flow of the peripheral, mesenteric, and retrobulbar arteries by CDI. Statistical significance was defined asPvalues less than 0.05. Blood flow in the radial and brachial arteries was significantly lower during needle stimulation on LR3 than before in healthy volunteers, but was significantly higher after needle stimulation than before. LR3 stimulation also resulted in a significant decrease in the vascular resistance of the short posterior ciliary artery and no significant change of blood flow through the superior mesenteric artery (SMA) during acupuncture. In contrast, ST36 stimulation resulted in a significant increase in blood flow through the SMA and no significant change in the vascular resistance of the retrobulbar arteries. Additionally, acupuncture at previously determined acupoints in patients with open-angle glaucoma led to a significant reduction in the vascular resistance of the central retinal artery and short posterior ciliary artery. Our results suggest that acupuncture can affect blood flow of the peripheral, mesenteric, and retrobulbar arteries, and CDI can be useful to evaluate hemodynamic changes by acupuncture.

At chronic opisthorchosis, disorders of venous blood flow in liver are observed in color Doppler liver mapping. To improve venous blood flow indices and the functional state of the hepatobiliary system as a whole, combined treatment should include factors not only ensuring the antiparasitic, antiphlogistic, and cholagogic effect, but also improving liver hemodynamics. This problem can be solved by combination of measures including morning exercises, pine baths, intake of cholagogic herbs with the following transversal galvanization in the epigastric region, and background x-ray radiation.

Placental Dysfunction

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.
