title: Intervention for renal artery stenosis: endovascular and surgical roles.
abstract: The treatment options for renal artery stenosis include bypass surgery, surgical endarterectomy, or balloon angioplasty with/without stenting. Each of these procedures is delivered today with differing frequency, morbidity/mortality, and outcomes. The procedure most applicable to patients with atherosclerotic disease is percutaneous transluminal renal angioplasty with stenting. Stents prevent plaque recoil, minimizing early restenosis, and the relatively large size of the renal artery (5-7 mm) minimizes late stent restenosis rates. The clinical features that help predict a favorable response to intervention are reviewed. In short, intervention provides a durable means to control renovascular hypertension, ischemic nephropathy, and congestive heart failure due to poor renal volume control.
