The anatomy of renal vascular variants plays an important role during planning of major procedures involving retroperitoneal spaces. The present observation revealed the coexistence of arterial and venous variants on the right kidney. A single right renal artery originates from the abdominal aorta at the level of fourth lumbar vertebrae and ascends superolaterally towards the hilum of the right kidney, arching above the inferior vena cava, leading to compression of the largest retroperitoneal vein. Accompanying this, a variant anastomosing vein connecting the right renal vein and the inferior vena cava was also observed. Understanding the existence of these variants is of important to clinicians, surgeons, urologists, radiologists, and cardiologists during their routine procedures such as nephrectomy, kidney transplant, and management of inferior vena cava syndrome and deep venous thrombosis.
肾血管变异的解剖结构在涉及腹膜后间隙的重大手术规划中起着重要作用。目前的观察发现右肾存在动脉和静脉变异。一条单一的右肾动脉在第四腰椎水平发自腹主动脉，超外侧向上朝向右肾门，在腔静脉上方呈弓形走行，导致最大的腹膜后静脉受压。与此同时，还观察到一条连接右肾静脉和腔静脉的变异吻合静脉。了解这些变异的存在对于临床医生、外科医生、泌尿科医生、放射科医生和心脏病专家在诸如肾切除术、肾移植以及腔静脉综合征和深静脉血栓形成的治疗等常规手术过程中具有重要意义。
