Presence of accessory renal artery and kinking of aorta due to the abnormal origin of renal arteries

A sound knowledge of variations of blood vessels is important during operative, diagnostic and endovascular procedures in the abdomen. This report describes the kinking of the aorta due to the variations in the origin of the renal arteries. The variation was found during routine dissection in an approximately 55 years old male cadaver. The cadaver was healthy and it did not have any other anomalies in the other parts of the body. The right and left renal arteries took their origin from the anterior aspect of the aorta just below the origin of superior mesenteric artery. There was a kink in the abdominal aorta above the level of the origin of these arteries. The cadaver also showed the presence of an accessory renal artery which took origin from the abdominal aorta, an inch above its bifurcation and entered the left kidney through lower part of its anterior surface. A good knowledge of vascular variations in relation to the kidneys is very important in kidney transplantation surgery.
