Abstract

The frequently to rarely occurring wide range of variations in the renal vasculature are considered critical issue that surgeons should have a thorough envision and appreciation of the condition. During the routine prosection hours for the preclinical MBBS students at Shadan Institute of Medical Sciences, Teaching Hospital and Research Centre, while dissecting a male cadaver revealed an interesting variation. The Main Renal Artery (MRA) was arising from the aorta about 1.8 cm below the Superior Mesentric Artery (SMA) extending laterally towards the hilum of the kidney. At about 1.5 cm below the origin of the Inferior Mesenteric Artery (IMA) from the antero lateral aspect of the Aortic Bifurcation, an aberrant renal artery measuring 4.5 cm in length, was seen coursing upwards, backwards and laterally & made its portal of entry by penetrating into the medial border and extending on to the posterior surface by piercing the capsule just half cm. above its lower pole. The ureter and the gonadal vessels were superficial to it. A thorough knowledge of the variations of renal vascular anatomy has importance in exploration and treatment of renal trauma, renal transplantation, renal artery embolization, surgery for abdominal aortic aneurysm and conservative or radical renal surgery.
