Syndrome of aorto-mesenteric compression is a rather rare pathology, and ultrasound diagnosis is the first method that does not invasively show the presence of this syndrome.

Purpose. Ultrasound diagnosis of the pelvic veins and determination of the diagnostic value of the proposed parameters in women with aorto-mesenteric compression syndrome.

Material and methods. The study included 46 women, the average age was 30.196 ± 7.17 years. The control group consisted of 23 non-pregnant women without venous and gynecological pathology. In general - 23 women: 15 operated women who had given birth with varicose veins of the pelvis, caused by aorto-mesenteric compression syndrome and 8 not operated, with characteristic complaints characteristic of pelvic varicose veins. Statistical data processing was performed using the StatSoft Statistica 10 software package.

Results. We studied the ultrasound diagnostic parameters of the pelvic veins: the left renal vein, the ovarian veins, the veins of the pelvic organs, the angle between the aorta and the superior mesenteric artery. In the veins, blood flow rates and their ratio, diameters and their ratio were measured. For indicators with identified intergroup differences between the main and control groups of patients, the average, minimum and maximum values of the indicators were determined. In the main group of patients, the correlation analysis did not reveal a functional relationship between the pressure gradient and other measurable indicators. When analyzing the correlations of other indicators of the main group (at p <0.05000), the coefficients show that a number of indicators have a relatively high connection tightness. A correlation analysis of the indicators of the control group (at p <0.05000) made it possible to identify a number of indicators that have a relatively high connection tightness.

In the study of rank correlations of the control and main groups, it was found that among the indicators having a statistically significant high closeness of communication, seven indicators coincided - the angles between the aorta and the superior mesenteric artery, the diameters of the left renal vein in different segments and their relationships. This suggests that the degree of closeness of the relationship between the observed indicators does not depend on the groups (main and control) for all patients observed.

Conclusion. The results indicate that some ultrasound diagnostic parameters, such as the ratio of linear blood flow velocity in the left renal vein of the distal segment to the stenotic, angle between the aorta and the superior mesenteric artery lying and standing can be used as defining statistical signs of the aorto-mesenteric syndrome.
