Renal artery stenosis (RAS) is a progressive manifestation of atherosclerosis. It is associated with hypertension and progressive renal failure. Noninvasive testing includes renal artery duplex, computed tomographic angiography (CTA) and magnetic resonance angiography (MRA). Percutaneous transluminal renal angioplasty and stenting (PTRAS) is indicated for significant atherosclerotic RAS while percutaneous transluminal renal angioplasty (PTRA) is indicated for fibromuscular dysplasias (FMD) associated with the proper clinical indications. PTRAS is associated with a high technical success rate and an acceptable adverse event and restenosis rate. PTRAS appears to improve control of hypertension and renal preservation. All patients should be followed clinically and with periodic duplex ultrasonography. Restenosis is treated with repeat angioplasty and occasionally stenting. Current and future areas of investigation will involve distal protection and drug eluting stents.
