A Case Report On Accessory Renal Artery and Accessory Renal Vein in Right Kidney

Abstract

Structural variations of the renal vessels are not uncommon. During the routine dissection of the abdomen for the under graduate teaching, it was found that the kidney on the Right side had an accessory renal artery and also an accessory renal vein. In our study of about 120 specimens observed in Anatomy Department from 2004 to 2012, this type of combination of variations was found only once, hence presented for its clinical importance. Vascularization of Kidney may be one of the interesting topics for both Anatomists and Surgeons. Variation in the numbers and arrangement of Renal arteries and their branches are not uncommon. These variations are of great importance to Surgeons. Because they can be the source of profuse bleeding if accidentally injured during surgeries. Generally each kidney has one artery and one vein. These variations in ureters and renal arteries are of immense importance because of their implications in various renal transplantations and surgeries. Thus the knowledge of these variations could help the clinicians in recognition and protection. II. CASE REPORT Accessory Renal Vein in Right Kidney: During the routine dissection in an adult male cadaver, it was found that Right Kidney had an accessory Renal Vein emerging just below the upper pole and nearer to hilum. It is opening to Inferior Vena cava (IVC) as shown in Fig.1. Accessory Renal Artery: Apart from the above variation, an Accessory Renal Artery was also found arising from the abdominal aorta at the level of L1 vertebral body as shown in the Fig. 2 and supplying the upper pole of the Right Kidney. Renal veins, Renal Arteries and the renal pelvis were normal in their origin, position and course. Ureters on both sides were normal in their length and size and they were opening to the lateral angle at the trigone of the bladder.
