Why is it important?
Introduction: Each kidney is supplied by a single renal artery originating from abdominal aorta at the level of L1 vertebra. Accessory renal arteries are common, they derive from the persistence of embryonic vessels formed during ascent of the kidney. We present, bilateral double renal vessels and unilateral accessory renal arteries discovered during a routine dissection of abdomen at department of Anatomy, Osmania medical college, during 20142018. Materials and Methods: Case1 We found 2 renal arteries running parallel to each other towards the hilum of the right kidney, both are derived from abdominal aorta. Case 2 Accessory renal artery originating from main renal artery entering the lower pole of the left kidney crossing superficial to hilar structures. Case 3 There is a crossing of the left renal artery over the renal vein disrupting the order of hilar structures. Case 4 Left Accessory renal artery arising from abdominal aorta below the renal artery supplying the lower pole of the kidney superficial to renal vein. Case 5 Left accessory renal artery arising from abdominal aorta, supplying the lower pole of the kidney passing below the renal vein. Case 6 Arterial trunk originating from right renal artery and supplying the suprarenal gland and diaphragm. Conclusions: The study was carried out among 60 cadavers and we found the variations in 14 cadavers . The incidence of the anomalies is 23.3%. Awareness of the variations of the renal artery is necessary for surgical management during renal transplantation, repair of abdominal aorta aneurysm, urological procedures and angiographic interventions.
