Bilateral quadruple renal arteries

Abstract

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.

Clinical importance of anatomical variations of renal vasculature during laparoscopic donor nephrectomy

“…The prevalence of multiple renal arteries on both sides is about 12% 19 . Rarely, four renal arteries on each side may be encountered during imaging work-up of 1.3% 16,19,20 . The most common variations of renal artery are excess renal arteries and early bifurcation.…”

Bilateral asymmetrical multiple renal arteries associated with the left testicular artery

“…Recently a great diversity of variations in renal arteries have been reported including bilateral quadruple renal arteries [8], bilateral triple renal arteries [14], bilateral multiple renal arteries associated with both testicular arteries [9], 9 renal arteries [4] and precaval renal artery [2]. In this report, we found an asymmetry of bilateral multiple renal arteries unlike former renal artery variations, since bilateral symmetry in the number of renal arteries was evident in 88.4% of cases [7].…”

Crossing Anatomic Barriers—Transplantation of a Kidney with 5 Arteries, Duplication of the Pyelocalyceal System, and Double Ureter

“…Miclaus and Matusz reported a case of a 58-yr-old male with bilateral quadruple renal arteries that were incidentally discovered with multidetector computed tomography angiography (MCTA). 9 Although the kidney was not utilized as an allograft, the case emphasized the prevalence of bilateral multiple renal arteries. Bilateral double and triple renal arteries have been reported in the past, but this case was the first to report bilateral quadruple renal arteries.…”
