Solitary Precaval Right Renal Artery: A Cadaveric Case Report and Review

Abstract

This study reports an extremely rare morphology and branching pattern of the right renal artery. During our routine dissection of a 52-year-old male body cadaver, we observed that the right kidney was receiving a single main renal artery, which passed anterior to the inferior vena cava (Perceval); the artery also, has a unique origin (the abdominal aorta). We think comprehensive knowledge of renal vascular abnormalities will enhance the proper interpretation of radiological images and enable safer interventions such as retroperitoneal surgical and urological procedures. Familiarity with the renal vascular anomalies would also be of particular importance during endovascular embolization, stent placement procedures, and surgical treatment of aortic aneurysms and reno-vascular hypertension treatment.
