[Origin and course of renal arteries. A CT study for determining optimal projection plane in renal artery angiography].

Abstract

In an attempt to optimize renal artery angiography we performed a CT-study. In 500 patients we determined the angle at which the arteries arise from the aorta and their course. Both renal arteries are in one plane, which is tilted 13 degrees ventrally on the right and 13 degrees dorsally on the left. More distally we found an angle of 35 degrees on the right and an angle of 29 degrees on the left in the dorsal direction. These findings were independent of age and sex of the patient.
