A Bilateral Multiple Renal Artery with Lobulated Left Kidney – A Case Report
A Bilateral Multiple Renal Artery With Lobulated Left Kidney
Keywords:
Additional renal artery, Variation of renal artery, Lobulated kidneyAbstract
Introduction: A precise knowledge of variation of the renal artery is essential for a variety of surgical and radiological procedures. Method: One such variation observed during routine educational dissection of a 65-year-old male cadaver at SMIMER, Surat. The cadaver was preserved using standard embalming technique and dissection carried out based on the method given in “CUNNINGHAM’S MANUAL OF PRACTICAL ANATOMY†Volume-II. Observation: (i) On right side an additional renal artery originated from the right side of abdominal aorta above the normal renal artery which soon divides into two branches which run parallel towards the renal hilum. The normal renal artery arches forward and downward in front of right renal vein and divides into two segmental arteries. The upper branch of additional artery give supra renal branch and continue as upper segmental artery while the lower branch divide into two segmental arteries. (ii) On left side one small additional renal artery originated from the left side of abdominal aorta above the normal renal artery and pass horizontally above left renal vein towards renal hilum. The normal artery arches behind left renal vein and divide into two segmental arteries. Another additional artery originated from left side of abdominal aorta just below the origin of inferior mesenteric artery run upward and laterally and divide into two segmental arteries one of which supply the accessory lobule of left kidney and another branch supply lower pole of left kidney. Conclusion: The comprehensive knowledge of variations of renal artery is the key issue in determining the technical feasibility of different surgical interventions of kidney.
