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.
我们报告了一例非典型病例，一名53岁男性，在用于检查下肢周围血管疾病的多排螺旋计算机断层扫描（MDCT）血管造影中偶然发现有六条肾动脉（RAs）（双侧各三条）。肾动脉从腹主动脉（AA）发出的最远端之间的距离，右侧为4.42厘米，左侧为2.40厘米。肾动脉穿入肾实质的最远端之间的距离，右侧为2.01厘米，左侧为2.56厘米。每侧主肾动脉起始处的管腔内直径（右侧为0.54厘米，左侧为0.42厘米）明显大于其他额外肾动脉（AdRAs）（右侧为0.21 - 0.29厘米，左侧为0.24 - 0.35厘米）；然而，额外肾动脉比主肾动脉长得多（右侧为7.42 - 10.82厘米，左侧为5.90 - 6.85厘米，主肾动脉右侧为6.21厘米，左侧为5.73厘米）。所有四条额外肾动脉均为肾门肾动脉。在规划适当的介入放射学和外科手术时，不应忽视这种解剖变异。
