Renal Artery Aneurysm Coexisting with Accessory Renal Artery

True aneurysms of the renal arteries are a very rare entity. Herein we describe a case of saccular left renal artery aneurysm found as an incidental angiographic finding in an adult, hypertensive female. She also had an accessory renal artery supplying the lower third of the left kidney. She underwent surgery, during which the large renal artery aneurysm was resected and the renal blood flow restored with aortorenal bypass graft with autologous saphenous vein. Postoperative recovery was uneventful, and her blood pressure is presently well- controlled (Iranian Heart Journal 2008; 9 (3):69 -72).
