VARIANT ANATOMY OF ADDITIONAL AND MULTIPLE HUMAN RENAL VEINS BY COMPUTER AND MULTISPIRAL COMPUTER TOMOGRAPHY DATA

Aim. To reveal the topographo-anatomic peculiarities of the structure of additional and multiple human renal veins by computer and multispiral computer tomography data. Materials and methods. Tomograms of 118 men and women obtained by means of spiral computer tomograph “Ultra Speed JE” and computer tomograms of 111 men and women in coronal projection obtained with computer tomograph “LightSpeed VCT” served as a material for investigation. Results. Kidneys with additional veins from the upper renal pole formed group 1 (12 observations). Kidneys with additional veins, which fell into the postcava higher than the level of the main trunk, but followed, unlike the previous group, from the renal hilum, formed group 2 (9 observations). Group 3 (5 observations) consisted of kidneys with additional veins from the lower renal pole which fell lower than the level of the main renal vein. In all the studied variants, presence of additional vein from the lower renal pole was associated with some peculiarities of topography of the kidney or its vessels. Conclusions. In 83,0 % of cases, a kidney has one renal vein, and in 17,0 % of cases there occur additional perforatory and multiple renal veins: additional veins were detected in 11,0 % of cases, perforatory veins - in 4,2 % of cases and multiple renal veins - in 2,0 % of cases.
