Accessory Renal Artery: A Cadaveric Case Report

Abstract

Introduction: The presence of Accessory Renal Artery, an anatomical variation has varying health implications and outcomes. Accessory Renal Artery is generally a vestigial structure caused by failure to degenerate during the ascent of metanephros.

Case Report: We found, 2 Accessory Renal Artery on anterior surface of right kidney. H&E examination revealed both were Accessory Renal Artery. The first artery lumen was obliterated while the second artery was patent. Thickness of 1^st Accessory Renal Artery at the site of insertion at kidney was 21.41 mm and thickness of 2^nd Accessory Renal Artery at the site of insertion at kidney was 21.28 mm. 5 segmental arteries divided 1 cm before entering the hilum.

Conclusion: Knowledge of such variations have great significance with the increasing number of renal transplants, vascular reconstructions and various surgical techniques performed in the recent years to avoid injury.
