Abstract
ABSTRACT
Background
The kidneys are supplied by a single renal artery originating from abdominal aorta.
However, recent literature reports great variations in renal blood supply. Hence, it
becomes mandatory for the clinicians to understand the abnormality and variations
in the renal vasculature.
Objective
To evaluate the branching pattern of renal artery and its variations.
Method
The study consisted of Computed Topographic images of 206 kidneys. Numbers and
branching pattern of renal artery were recorded. The data was analyzed for presence
or absence, source of origin and type of accessory renal artery.
Result
The present study revealed that 73.79% of kidneys were supplied by a single renal
artery, 25.72% by double renal artery and 0.49% by triple renal artery. The hillar
branching pattern was recorded in 38.83% and early branching pattern was in
34.95%. The presence of accessory renal artery was recorded in 26.21%. They were
originated from abdominal aorta in 22.81% and 3.40% from main renal artery. The
prevalence of superior polar artery was found in 6.79%, hilar in 10.19% and inferior
polar in 9.22%.
Conclusion
The knowledge of variations of renal artery becomes essential for the clinician to
plan the adequate surgical procedures and to avoid any vascular complication.
