Objective: This study is aimed at exploring the accuracy of contrast-enhanced ultrasound (CEUS) in grading renal artery stenosis. Procedures to treat renal artery stenosis may include: Renal angioplasty and stenting. In this procedure, doctors open wider the narrowed renal artery and place a device inside your blood vessel that holds the walls of the vessel open and allows for better blood flow. Prognosis The outcome of renal arterial occlusion depends on the speed with which it is treated. Once the blood supply is minimized or cut off to the kidney, tissue death soon results, ultimately leading to chronic kidney failure (end-stage renal disease). Epub 2012 May 15.
