摘要

Renal artery aneurysm (RAA), a type of visceral aneurysm often presenting with nonspecific symptoms, is challenging to diagnose and is typically detected incidentally during imaging examinations. Saccular aneurysms of the renal artery can cause significant compression of the renal parenchyma. In this case, we report a 23-year-old woman diagnosed with a giant saccular left RAA measuring 13 cm × 11 cm × 11 cm. She successfully underwent endovascular treatment involving covered balloon-expandable stent implantation followed by occlusion of the left renal artery branch supplying the aneurysm. The patient was discharged without any complications. This case is notable for the aneurysm’s unusually large size in the left renal artery compressing the renal parenchyma, posing a challenge in maintaining adequate blood flow to the left kidney. The innovative endovascular approach not only resolved the aneurysm but also preserved the blood supply to the affected kidney. Endovascular therapy proves to be an effective strategy for managing a giant RAA.
