Study on variations in segmental branching pattern of renal artery
Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 3
Abstract
Introduction: With the increasing use of renal transplantation, segmental resection and renal reconstructive surgeries, knowledge of the variations in the segmental branching pattern of renal artery has grown in importance. Material and methods: In the present study carried out on 42 adult kidneys by dissection method, we found different types of variations in all the segmental branches of renal artery. Results: From Anterior division, apical segmental artery was seen to be taking origin in 23%, middle segmental artery in 67%, upper segmental artery in 42.% and lower segmental artery in 73% kidneys. Apical segmental artery took origin from upper segmental artery in 37% and from middle segmental artery in 3% kidneys. Middle segmental artery originated from upper segmental artery in 7% and from lower segmental artery in 23% cases. Posterior segmental artery was seen as conventional arching pattern in 57%, seen to be bifurcated or trifurcated in 30% and larger than anterior division in 10% kidneys. It was seen to be giving origin to other segmental branches variably. Renal artery and aorta were also seen to be contributing to these branches to a large extent. Discussion: Knowledge of segmental branching pattern of renal artery is having surgical importance in making a relatively bloodless surgical approach to the kidneys and to save healthy renal tissue in partial nephrectomy and nephrolithotomy.
