Incidence and Variations of Aberrant Renal Arteries in Kidney Donors Cases

Abstract

The origin of renal arteries, vessel diameter, and point of entry to the kidney has all been analyzed as potential parameters which are a clinically relevant issue. This anatomical feature may be essential for fully understanding the process of renal perfusion, as it is not only the number of renal arteries that influences the extent of renal blood supply, also their diameter. The aberrant renal arteries that supply the inferior pole are more important because it provides arterial supply to the proximal part of the ureter. The objective of this study is to identify influences and prevalence of aberrant renal arteries of the kidney donors' cases to perform role of the aberrant renal artery.Prevalence of aberrant renal artery was identified in 26.3% of the cases, incidence was more frequent in left than right side; about 78.7 % of cases presented unilaterally. The remaining cases 21.2 % were RAs presented bilaterally. Diameter of main RA in kidney presenting the RA was 5.73 mm and that of kidney with only single renal artery was 6.19 mm.

Kidney malrotation with aberrant renal arteries and extra-renal calyces - case report

“…There are different kinds of renal arterial supply variations, some others divide the renal arterial variants into 2 groups: early division and extra renal artery, but others use supernumerary, multiple, and aberrant. The current case falls into the extrarenal artery or aberrant group as the kidney has two additional arteries to the main renal artery, similar to what was reported by Monam & Najjar [10] that one kidney had three renal arteries (two aberrant renal arteries and one main renal artery), this was identified in 2.7 % of kidneys that they studied. This case may make a partial nephrectomy procedure of either the superior pole or the inferior pole more challenging due to the branching patterns of the renal artery and vein.…”

“…Finally, the ascent of the kidney is arrested by the diaphragm where it gets permanent arterial supply from the lowest supra renal artery and persists as a definitive renal artery [9]. This happens due to the degeneration of developing metanephric arteries leaving only one mesonephric artery, failure in the degeneration of other mesonephric arteries results in an aberrant renal artery [10]. There are different kinds of renal arterial supply variations, some others divide the renal arterial variants into 2 groups: early division and extra renal artery, but others use supernumerary, multiple, and aberrant.…”

Evaluation of Clinical Implications of Renal Vessel Morphology during Renal Surgeries

“…Patients with late renal vein confluence 3 (3.3%) and retroaortic vein (3.3%) were seen on the left side. According to Zainel MA et al (2020) [19], 26.3% of the Iraqi population had abnormal renal arteries, according to their findings in Iraq. To begin with, it's more prevalent on one side (32.1 percent) than the other (20.7 percent ).…”
