PURPOSE: The purpose of this study is to introduce the experience of 31 patients who had renovascular hypertension and underwent percutaneous transluminal angioplasty of renal artery (PTA). MATERIALS AND METHODS: The subjects were 31 patients with hypertension and stenotic renal artery or arteries on angiography. The criteria of stenosis is more than 50% narrowing of the artery. The technical results were considered to be successful if residual stenosis is less than 50%. The clinical results were classified as cure, improvement and fail. And clinical results were analyzed according to the follow-up duration, short term (< or = 6 mo) and long term (< 6 mo). RESULTS: Technical success rate was 90.2% (37/41) and clinical success rate were 82.8% (24/29) on short term follow-up and 84.2% (16/19) on long term follow-up. Recurred cases were 7 cases. CONCLUSION: PTA is a safe and effective therapeutic modality on renovascular hypertension.
