title: Medical therapy is best for atherosclerotic renal artery stenosis: Arguments for.
abstract: Atherosclerotic renal artery stenosis (ARAS) is a common condition that causes hypertension and reduction in the glomerular filtration rate and is an independent risk factor for death. Despite high technical success, the clinical benefit of renal artery (RA) angioplasty with stenting in ARAS remains doubtful. The published randomized clinical trials provide no support for the notion that renal angioplasty with stenting significantly improves blood pressure, preserves renal function, or reduces episodes of congestive heart failure in patients with ARAS. RA stenting is associated with procedure-related morbidity and mortality. Agents to block the renin-angiotensin-aldosterone system improve outcome and should be a part of a multifaceted medical regimen in ARAS. Medical therapy effectively controls atherosclerotic renovascular disease at all levels of vasculature and hence is the best therapy for ARAS.
