Long-term clinical outcome of patients with severe atherosclerotic renal artery stenosis after percutaneous transluminal renal angioplasty

Background In the patients with severe atherosclerotic renal artery stenosis (ARAS), the evaluation of long-term clinical outcome after percutaneous transluminal renal angioplasty (PTRA) has yet been insufficient. The aim of this study was to focus on only patients with severe ARAS and to evaluate the more long-term clinical outcome after PTRA.
