Percutaneous Stent-Graft Management of Renal Artery Aneurysms

JVIR 2000; 11:1189–1193 RENAL artery aneurysms (RAAs) are rare, with a reported incidence of 0.015%–1.32% (1–3). Although most RAAs may be safely observed, indications for treatment include a size more than 2.5 cm, interval enlargement, renovascular hypertension, pain, hematuria, intrarenal thromboemboli, and lesions in women of childbearing age (1,2,4,5). Traditionally, the definitive management of RAA has consisted of operative repair or nephrectomy. Although stent-grafts have been used for the exclusion of aortic and iliac aneurysms (6), there exists, to our knowledge, only a single published case description of stentgraft exclusion for the treatment of RAA (7). In this report, we describe our experience with two cases of percutaneous RAA exclusion with use of polytetrafluoroethylene (PTFE)-covered Palmaz stents (Cordis, Warren, NJ).
