Стереоанатомический анализ артериальной системы почки человека
2015
Aim. To study the spatial and level organization of different arterial canal links in the human kidney. Materials and methods. Forty preparations of kidneys from persons aged 22-90 years who died from diseases not connected with renal pathology served as a study material. The methods of anatomical preparation, those of producing corrosive preparations of renal arterial system followed by their 3D-scanning were used. Variants and types of arterial vessel branching were studied in stereoprojection. Results. It was detected that the renal artery was divided into two branches (85 % of cases) on 34 out of 40 corrosive preparations of renal arterial vessels. On 6 out of 40 corrosive preparations of renal arterial vessels the renal artery was divided into 3 branches (15 % of cases). Results. The results of stereoanatomical studies of renal arterial vessels showed that spatial and level organization of different links of renal arterial canal depends on both variants of division and types of intraorgan branching of renal arterial system. Conclusions. Taking into account the types of intraorgan branching of renal artery and level organization of links, there is observed a quantitative and qualitative difference in the number of vessels of the third and forth link, that influences the number of segments in the kidneys, thus resulting in reconsideration of a classical five-segmental structure of the kidney.
