The frequency of different plural renal arteries rare variants.

The aim of this work was to evaluate the frequency of different plural renal arteries rare variants in healthy patients and in many different pathological diseases. Abdominal aortography with following selective angiography was performed on 35 randomly selected patients of Medical Department, with the use of radiopaque and with followed radiological parameters: P--75 kV, I--9 mA, T--10 sec. According to the available literature the following classification was introduced: double renal arteries--two vessels originating from the aorta, similar in diameter, blood supply areas, and their branches entering kidney through hilum (observed in 20% of cases), triple renal arteries--three vessels originating from the aorta with different diameter and blood supply areas, and their branches entering kidney through hilum (observed in 3%), upper pole accessory artery--originates from aorta, diameter of which being comparable to segmental arteries, entering kidney through hilum (6%), lower pole accessory artery (40%), upper pole perforating artery--originates from aorta or one of its major branches, diameter of which being comparable to segmental or subsegmental arteries, supplying one segment only, entering kidney outside of hilum (26%), and lower pole perforating artery (3%).
