THE INFLUENCE OF SYNTOPY OF THE AORTA AND LEFT RENAL VEIN ON THE HYDRODYNAMICS OF THE LEFT RENAL VEIN BASIN

Relevance. The article analyzes the syntopy of the aorta and the left renal vein, as well as the hydrodynamic effect of the aorta on the hemodynamics of the left renal vein basin. Aim. To study the relationship between the syntopy of the aorta and the left renal vein, as well as the hydrodynamic effect of the aorta on the left renal vein. Materials and methods. One hundred corpses from 16 to 62 years old were selected for the study. All of them had no changes or damage to blood vessels in the studied area. Full name, gender, age, cause of death and date of autopsy were recorded. Calculations were carried out using mathematical and hydrodynamic research methods. Results. With the retroaortic location of the left renal vein, the pressure in the vessel increases. From the peculiarities of the overlap of the left renal vein on the aorta, it follows that the larger the area of application, the greater the pressure exerted by the pulsation from the aorta on the renal vein. Considering that in the layer of fluid adjacent to the surface of the vein the flow velocity is close to zero, one would expect a pulsating flow in the opposite direction, but due to the presence of pressure in the vein providing blood flow, this does not happen. Conclusion. It has been studied that the outflow of blood from the left renal vein basin is influenced by both compression of the venous vessel and pulse pressure
