“…This information is especially necessary when performing segmental resections or organpreserving kidney operations using modern 3D technologies 2,3 . According to some authors, for the successful performance of surgical interventions, clinicians pay close attention to the structural features of the renal arteries and veins, as well as to the topographic and anatomical features of their position in the renal hilum related to the pelvis 3,4 . Particular attention in clinical practice is paid to the questions concerning the variants of the division of the renal arteries at the hilum of the kidney, their intra-organ branching in the parenchyma of the organ, and the structural features of the venous link of the vascular bed of the kidney involved in the processes of drainage of the parenchyma, thereby maintaining normal hemodynamics in the kidney, metabolic processes, etc [4][5][6] .…”

Purpose of the study:To review the zonal features of the blood supply to the kidneys and to identify the venous basins, depending on the options for the structure of the arterial and venous bed of the kidney. Materials and methods. The study was carried out on 124 polychrome corrosive preparations of the arterial and venous systems of the human kidney. For digitization, the preparations were subjected to 3D scanning. The authors identified the zones of local blood supply to the areas of the renal parenchyma and venous drainage depending on the variants of the division of the renal artery and the fusion of the renal vein in a 3D projection in a computer program. Results. It has been established that the features of the local regional blood supply to the kidney zones and venous outflow from its parenchyma have a dependence associated with the variants of the division of the main renal artery in the renal hilum on the 2nd order arteries, that is, zonal arteries, A. zonal (II), which have their own quantitative and topographic characteristics in the hilum of the kidney, and later in the parenchyma of the organ, where they form the corresponding vascular basins. Conclusion.The structure of the vascular basins will depend on the loose or magistral types of intra-organ branching of the zonal arteries, A. zonal (II) into the arteries of the 3rd, 4th, etc. order. The system of venous outflow from the kidney has a similar structure, except for the absence of zones or regions of isolated venous outflow from the kidney.

“…Ischemic heart disease is defined by decreased cardiac blood flow, which throws off the balance between the oxygen supply and demand in the myocardium [1][2][3]. Most typically, coronary artery disease (CAD), caused by atherosclerotic spasm or blockage of the epicardial coronary arteries, or microvascular dysfunction, is the underlying clinical mechanism.…”

The primary aim of this systematic review is to examine the published research on the connection between cold exposure and ischemic heart disease (IHD). We conducted a systematic search through PubMed, Web of Science, Science Direct, EBSCO, and the Cochrane library. Using Rayyan QCRI, study articles were first screened by title and abstract before a full-text analysis was implemented. A total of six studies with 281979 patients were included. We comprised various cold events, including cold work environments among workers, cold spells, usual cold exposure, and prolonged extreme cold. Two studies reported that cold exposure among workers and the general population increases the risk of mortality rate due to myocardial infarction (MI). In CAD patients, prolonged severe cold exposure worsens coronary events (signs and symptoms). This comprehensive review indicated that exposure to the cold increased the risk of MI-related death in both workers and the general population. Furthermore, continuous exposure to extremely cold conditions makes coronary events worse in people with CAD.
