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.
肾动脉（RA）数量的变化是最常见和临床上最重要的肾血管变异。在本研究中，作者描述了一例罕见的 58 岁男性病例，该患者通过常规多层螺旋 CT 血管造影显示有 8 支 RA（双侧四支）。所有 8 支 RA 均发自腹主动脉，在肾窦水平穿入肾实质。主要 RA 的腔内直径大于起源处的附加肾动脉（AdRA）的直径。所有 AdRA 的长度均大于主要 RA。这些方面在规划显微外科手术时尤为重要。
