Knowledge of the anatomical variations of the visceral branches of the abdominal aorta is important information for planning any surgeries in the region. We present here a rare constellation of variations of visceral vessels around the kidneys with a brief review of the recent literature. On the right side, an accessory renal artery was observed originating just distal to the main renal artery. The middle suprarenal artery was absent on the right side and there were two inferior suprarenal arteries originating from a branch of the main right renal artery. On the left side, the testicular artery had an arched course anterior to the left renal vein mimicking an unusual variety of nutcracker phenomenon. The right kidney was drained by two renal veins into the inferior vena cava. Knowledge of the coexistence of such complex anatomical variations might be helpful for clinicians during diagnostic and therapeutic procedures.
了解腹主动脉内脏分支的解剖变异是该区域任何手术规划的重要信息。我们在此呈现一组罕见的围绕肾脏的内脏血管变异情况，并对近期文献进行简要综述。在右侧，观察到一条副肾动脉起源于主肾动脉远端。右侧无肾上腺中动脉，有两条肾上腺下动脉起源于右主肾动脉的一个分支。在左侧，睾丸动脉在左肾静脉前方呈弓形走行，类似一种不寻常的胡桃夹现象。右肾通过两条肾静脉汇入下腔静脉。了解这种复杂解剖变异的共存情况可能对临床医生在诊断和治疗过程中有所帮助。
