Aneurysms of the renal artery are very rare and its incidence is estimated at 0.01% of population. A 50-year-old male was admitted to the Department of General and Vascular Surgery due to incidentally diagnosed aneurysm of the left renal artery. Due to wide neck of the aneurysm, a two-step procedure was planned. First, an intracranial stent was implanted into the left renal artery. Second, after 3 months, platinum coils were deposed in the aneurysm sac through the stent struts. Aneurysmal sac was totally occluded. Periprocedural course was uneventful. The endovascular embolization with the use of stent and detachable coils is a safe method of treatment of wide-necked renal artery aneurysms with preserving parent vessel patency.
