Interventional therapy for hypertension caused by atherosclerotic renal artery stenosis——analysis of 30 cases

Objective: To analyze the effect of interventional therapy for hypertension caused by atherosclerotic renal artery stenosis.Materials and Methods: Thirty cases of hypertension caused by atherosclerotic renal artery stenosis were enrolled.Eight patients accepted percutaneous renal angioplasty.Another 22 patients accepted percutaneous renal artery stenting.Results: All procedures were finished successfully.Sixteen patients regained normal blood pressure after operation.Ten patients obtained amelioration.The total effective ratio was 86.7%.All patients were followed by CTA from 36 to 148 days,mean 96 days.All stents remained patent during the follow up period.Restenosis occurred in 3 patients who have accepted percutaneous renal angioplasty.The recurrent ratio was 37.5%.Conclusion: Percutaneous renal artery stenting was predominant therapy for hypertension caused by atherosclerotic renal artery stenosis.
