Bilateral quadruple renal arteries

Variation in the number of renal arteries (RAs) constitutes the most common and clinically important renal vascular variation. In this study, the authors describe a rare case of a 58‐year‐old male with eight RAs (bilateral quadruple) as revealed by routine multidetector computed tomography angiography. All the eight RAs originated from the abdominal aorta and penetrated the renal parenchyma at the level of renal sinus. The main RAs had the intraluminal diameter larger than the diameter of the additional renal arteries (AdRAs) at the origin. All the AdRAs had a greater length than the main RAs. These aspects are particularly important in planning microsurgical procedures. Clin. Anat. 25:973–976, 2012. © 2012 Wiley Periodicals, Inc.
