Randomized Controlled Trial Multicenter Study
Stent placement in patients with atherosclerotic renal artery stenosis and impaired renal function: a randomized trial.
Little is known about the efficacy and safety of renal artery stenting in patients with atherosclerotic renal artery stenosis (ARAS) and impaired renal function. ⋯ Stent placement with medical treatment had no clear effect on progression of impaired renal function but led to a small number of significant procedure-related complications. The study findings favor a conservative approach to patients with ARAS, focused on cardiovascular risk factor management and avoiding stenting.
