A accessory renal artery arising from the lumbar artery

Abstract Background The presence of accessory renal arteries is a common variation of the renal artery and is important for surgical planning. These arteries are typically reported to originate from the abdominal aorta, common iliac artery, or mesenteric arteries, but there have been no reports of accessory renal arteries originating from the lumbar artery. Case presentation A dynamic enhanced scan of the kidneys with virtual reality display showed two blood supply vessels to the left kidney. One vessel originated from the abdominal aorta and supplied the upper and middle portions of the kidney, while another vessel originated from the left lumbar artery and supplied the lower portion of the kidney. Conclusion This case highlights a rare variation of the renal artery, where an accessory renal artery originates from the lumbar artery. Understanding such variations is crucial in surgery to avoid complications.
