We report an atypical case of a 63-year-old male with the presence of seven renal arteries (RAs) (three right and four left) found incidentally on multi-detector computed tomography (MDCT) angiography which was used to investigate peripheral vascular disease of the lower limbs. Each arterial lumen was analyzed for the diameter at its origin; length and trajectory in the frontal plane (ascendant + or descendant -); and the distance between the point of origin from the abdominal aorta (AA) to its renal intraparenchymal penetration point. We also analyzed the distance between the extreme points of origin of the right and left RAs from the AA and the distance between the extreme points of penetration into the renal parenchyma of the right and left RAs. On each side, the endoluminal diameter at the origin of the main RA was significantly larger than that of the other AdRAs; however, the AdRAs were much longer than that of the main RA. From the six AdRAs, four were hilar RAs and two were superior polar RAs. Knowledge of such cases is of great clinical significance, as it may be beneficial in various urological operations or invasive arterial procedures.
我们报告了一例非典型病例，一名63岁男性，在用于检查下肢外周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七条肾动脉（RAs）（右侧三条，左侧四条）。对每条动脉管腔的起始直径、在额面的长度和走行（上升为+或下降为-）以及从腹主动脉（AA）的起始点到其肾实质内穿入点的距离进行了分析。我们还分析了左右肾动脉从腹主动脉的起始端点之间的距离以及左右肾动脉穿入肾实质的端点之间的距离。在每一侧，主肾动脉起始处的管腔内直径明显大于其他副肾动脉；然而，副肾动脉比主肾动脉长得多。六条副肾动脉中，四条是肾门肾动脉，两条是上极肾动脉。了解此类病例具有重要的临床意义，因为这在各种泌尿外科手术或有创动脉手术中可能是有益的。
