摘要

Anomalous blood vessels are always interesting from a purely scientific point of view, especially since they so often shed light on obscure problems of phylogeny and ontogeny. The evolutionary history of kidney & renal artery is recapitulated during embryonic development .Most of the variations of human renal vessels can be explained on the basis of phylogeny as many conditions which are anomalous in human are normally present in some animals. The most common variation of renal artery is the presence of an accessory renal artery, occurring in approximately 30% of cases.Aims: The present study was undertaken with the aim to study the accessory renal artery in human as well as in some other vertebrates and to make an attempt to explain them on ontogenetic & phylogenetic basis.Materials and Methods: Material of this study comprised of 30 adult human cadavers (60 sides) and 30 animals of specifiedvertebrate series. These were dissected to expose the kidneys and their arterial supply. The renal and accessory renal arteries were traced up to their origin from abdominal aorta.Result and Discussion: In this study, in all experimental animals except mammals multiple renal arteries were found. In human beings the accessory renal arteries were found in 17(28.3%) kidneys. All of these were compared for understanding of the phylogeny and ontogeny of accessory renal arteries. Further an attempt has been made to discuss their clinical and surgical significance.Conclusion: We as anatomist believe that knowledge and awareness of causes of these accessory renal arteries are necessary for better surgical management during urological procedures & angiographic interventions as well as to design newer technique for them.
