Unilateral multiple variations of renal, phrenic, suprarenal, inferior mesenteric and gonadal arteries

Abstract

Knowledge of the branching pattern of the abdominal aorta is clinically important for any abdominal surgeon operating on parts of the gut or neighboring structures. Variations of these vessels may influences urological, renal transplantation and laparoscopic surgeries. We present an unreported case of multiple variations of branching pattern of abdominal aorta. It includes double renal arteries for left kidney, a common trunk with right and left phrenic, right and left superior suprarenal and left middle supra renal arteries, and a common trunk originate 2.5 cm above the bifurcation of abdominal aorta gave off inferior mesenteric, accessory renal artery to the left kidney and left testicular arteries in the middle-aged normal male cadaver. The embryogenesis of such multiple variations of branches of abdominal aorta is not clear, but the anatomic consequences may have important clinical implications. Knowledge of these variations is important for urologists, radiologists and surgeons in general.
