AN UNIQUE ASYMMETRICAL BILATERAL VARIATION OF RENAL ARTERY: RIGHT SIDED EARLY DIVISION AND LEFT SIDED ACCESSORY/ ADDITIONAL ARTERIES

Variations in renal arteries are common due its complicated development, ascent and rotation. Estachius first described a case of multiple renal arteries in 1552. These arteries frequent at the inferior pole rather than the superior pole of kidneys. Additional renal arteries may or may not be associated with the congenital malformations of the kidneys. We report a unique asymmetrical bilateral variation of renal artery with right sided early division and left sided accessory/ additional arteries. It is not associated with any other anomaly of kidneys. All of these branches entered the kidney through the hilum. This ob¬servation has clinical relevance for surgery, imaging, interven¬tional radiological procedures as well as other diseases of kidney. Since renal arteries are end arteries; early branches and multiple arteries need to be attended individually during renal transplantation surgeries for better outcome.
