Angio-embolization of a Large Renal Artery Aneurysm: A Case Report and Literature Review

We report a rare case of a large 7.8 cm renal artery aneurysm with subsequent successful endovascular coil embolization. A 54-year-old lady presented with a 3-day history of gross hematuria. Computed tomography (CT) angiogram revealed a large 7.8 cm right renal artery aneurysm, which was successfully embolized with endovascular coils. 1-month and 12-months surveillance showed preservation of renal function with decreasing aneurysm size. Endovascular coil embolization of large renal artery aneurysm is a safe and viable treatment modality. Literature review demonstrates good treatment outcomes, with technical success rates of >90% and complication rates of <10%.
