Renal artery aneurysms are very rare: mostly they are saccular aneurysms with a wide or strict neck. The most fearsome complication is the rupture: to avoid and prevent the rupture it is necessary to perform the exclusion from vascular stream of the aneurysm. The traditional surgical approach is represented by aneurysmorrhaphy, by-pass or combined approaches, but reported morbidity and mortality are respectively 1.6% and 12%. However, in the last two decades many authors reported endovascular approaches for renal artery aneurysms exclusion. The endovascular approach is represented by the exclusion of the aneurysm by releasing coils into the division branch of renal artery proximally to the aneurysm and the endovascular embolization of the aneurysm sac, in cases with a strict neck, and the implantation of covered stents in cases of aneurysms with a wide neck. In this manuscript we report the case of a big saccular aneurysm with a wide neck of the main anterior branch of right renal artery successfully treated with endovascular placement of covered stents.
