Results of percutaneous transluminal angioplasty for atherosclerotic renal artery stenosis: A follow-up study with duplex ultrasonography

Purpose: The short and long-term anatomic results of percutaneous transluminal renal angioplasty (PTRA) in the treatment of atherosclerotic renovascular disease have been poorly documented because of a lack of follow-up arteriography. The purpose of this study was to evaluate the anatomic results of PTRA with serial duplex examinations. Methods: The records of 41 patients who underwent 52 primary PTRA procedures and had subsequent duplex follow-up of at least 6 months were reviewed. After PTRA, renal arteries were classified as normal,
