Overview
Brief Summary
The clinical investigation is a prospective, international, multi-centre, randomized (1:1) trial with follow ups at 2, 6, 12 months and 3 years.
The purpose of the study is to evaluate the clinical impact of percutaneous transluminal renal artery stenting (PTRAS) on the impaired renal function measured by the estimated Glomerular Filtration Rate (eGFR) in patients with hemodynamically significant atherosclerotic renal artery stenosis (ARAS).
