3D Analysis of Topographic and Anatomical Features of the Arterial and Venous Vessel Structure in Kidney

The study aimed to review the topographic and anatomical features of the intra-organ structure of the arterial and venous bed of the human kidney. 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. In a computer program, in a 3D projection, the zones of local blood supply to the areas of the renal parenchyma and venous drainage were identified, depending on the variants of the division of the renal artery and the fusion of the renal vein. The analysis of polychrome corrosive preparations of arterial and venous vessels of the kidneys revealed 17 topographic and anatomical variants of the division of the arterial bed and formation of the venous bed of the kidney, where the main trunks in the renal hilum relative to the sagittal, frontal and horizontal planes occupied different positions. The 3D analysis of polychrome corrosive preparations of arterial and venous vessels of the kidneys showed that the great arterial vessels in 30.0% of cases repeated the course of the cognominal venous vessels, both concerning their location in the hilum of the kidney relative to the sagittal, frontal and horizontal planes, and their course, and topography in the parenchyma of the organ.
