ABSTRACT
Objective: To evaluatethe efficacy of renal artery stenting combining optimal drug therapy in patients with atherosclerotic renal artery stenosis. Methods:This is a prospective cohort study for patients who received percutaneous renal artery stenting in our hospital from 2011-09 to 2013-03. All patients had conifrmed diagnosis of atherosclerotic renal artery stenosis combing hypertension and/or renal functional damage. Thepatients received optimal drug therapy for anti-platelet and blood pressure, lipids, glucose controlling, and they were followed-up for at least 12 months to observe the improvement of blood pressure and renal function. Results:There were 149 patients at the mean age of (61.54 ± 9.63) years and 185 renal artery stenosis with stent implantation;the average stenosis rate was (83.11±7.30)%and the success rate of operation was 99.32%(148/149). During follow-up period, the patients had increased estimated glomerular ifltration rate (GFR) compared to base line from (76.49 ± 22.50) ml/(min·1.73 m2) to (84.09 ± 28.79) ml/(min·1.73 m2), P Conclusion:Renal artery stenting combining optimal drug therapy may improve blood pressure controlling and renal function in strictly selected patients with atherosclerotic renal artery stenosis.
