Atherosclerotic renal artery stenosis (ARAS) is the most common cause of renal artery stenosis in the adult population. ARAS may result in progressive renal impairment, renovascular hypertension, and/or cardiac disturbance syndromes. ⋯ When performed correctly, renal artery stenting has been shown to stabilize or improve renal function and/or renovascular hypertension in 65-70% of carefully selected patients with ARAS. Therefore, percutaneous renal artery stenting should be considered the primary treatment for patients with symptomatic ARAS.
