Accessory Renal Vessels

Abstract

Knowledge of the variations of the renal artery has grown in importance with increasing of renal transplants, vascular reconstructions and various surgical and radiologic techniques performing in recent years. We report the presence of unilateral doubled renal vessels, discovered on routine dissection of a male cadaver, on the right side; additional renal artery originated from the abdominal aorta. In addition the right suprarenal gland received arteries from right renal and inferior phrenic arteries only. The right inferior phrenic originated from the right renal artery.

Morphological and clinical aspects of the occurrence of accessory (multiple) renal arteries

“…Natsis et al [ 41 ] reported no statistically significant relationship ( p > 0.05) between gender and the side on which the supernumerary renal artery was situated. However, several authors have observed a higher incidence in males than females [ 3 , 61 , 64 , 82 , 83 ], whereas others conclude the opposite [ 56 , 66 , 84 , 85 ] ( Table IV ).…”

A cadaveric study of lower polar supernumerary renal arteries. – Embryological and clinical consideration

“…[8] ( fig.1,2,3) Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, nephrectomies, segmental resection and various surgical and radiologic techniques being performed in recent years. [9] Transplanting a kidney with accessory renal arteries has several theoretical disadvantages like acute tubular necrosis and rejection episodes and decreased graft functioning [4] . Knowledge of supernumerary renal arteries is essential before performing any transplantation surgeries since microvascular techniques can be employed to reconstruct the renal arteries during end to end anastomosis.…”

Abnormal origin of left ovarian artery from the inferior renal polar artery - a rare anatomical variation

“…The right renal artery is longer and often higher than the left. Although a single renal artery supplying each kidney is classically described, it is subject to anatomical variations frequently 2 . Knowledge of these anatomical variations of the renal vasculature is of great importance with the advent of vascular reconstructive surgeries, renal transplants, and various radiological and urological procedures carried out in this region 2 .…”
