[Angiographic imaging of supernumerary kidney arteries by nonselective angiography]

In this paper was examined the occurrence frequently more of one kidney artery of the aortic origin. The examinations were performed on the 213 angiograms of the kidney artery by the method of the unselective renal angiography per Seldinger, in both sexes, of the various life ages. On the analyzed angiograms was the presence of these arteries in 25.82% of cases. They were more often at the right side in 49.09%, than on the left side in 36.36%, while their both side presence was found in 14.55%. Although are these arteries more frequently in male persons, a though the sex cannot be statistically significant the parameter for the determination the frequency of their occurrence. In the relation to the backbone column the level of the exit of this arteries from the aorta is the greatest number of cases between the trunk of the first and third loins vertebra (L1-L3) and all were directed according to the medial edge of the corresponding kidney. According the place of the entrance in the kidney can be differed three types of these arteries: the artery, and upper and low polar artery. On the analyzed angiograms most often were found the hilar and lower polar artery, while the upper polar artery was present in only seven cases of the total number of the analyzed angiograms. We consider that the recognition of the supernumerary arteries of the kidney there is both anatomically and the significance in the surgical and radiological practice and their best identification achieves by the application of the angiographic radiology methods.
