Renal function and outcome of PTRA and stenting for atherosclerotic renal artery stenosis

摘要

Renal function and outcome of PTRA and stenting for atherosclerotic renal artery stenosis.BackgroundPrior studies of percutaneous transluminal renal artery angioplasty and stenting (PTRAS) for atherosclerotic renal artery stenosis (RAS) have shown that renal function is improved in about 25%, stabilizes in about 40%, but worsens in about 25% of patients. The factors predicting benefit remain controversial. We tested the hypothesis that the baseline glomerular filtration rate (GFR) predicts the changes in GFR and blood pressure (BP) after PTRAS.
