Abstract:
We report an atypical case of a 53-year-old male with the presence of six renal arteries (RAs) (bilateral triple) found incidentally on multi-detector computed tomography (MDCT) angiography, which was used to investigate peripheral vascular disease of the lower limbs. The distance between the extreme points of RAs origin from abdominal aorta (AA) was in right 4.42 cm, and in left 2.40 cm. The distance between the extreme points of penetration into the renal parenchyma was in right 2.01 cm, and in left 2.56 cm. On each side, the endoluminal diameter at the origin of the main RA (in right 0.54 cm, and in left 0.42 cm) was significantly larger in comparison with the other additional renal arteries (AdRAs) (in right 0.21-0.29 cm, in left 0.24-0.35 cm); however, the AdRAs were much longer (in right 7.42-10.82 cm, in left 5.90-6.85 cm) than the main RA (in right 6.21 cm, in left 5.73 cm). All the four AdRAs were hilar RAs. Knowledge of this anatomical variation should not be ignoring when planning the adequate interventional radiological and surgical procedure.

Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...
