Objective : To evaluate long term efficacy of percutaneous transluminal renal angioplasty (PTRA) for renovascular hypertension in patients with arteritis- Methods : From March 1983 to Sept- 1988 ,ten patients with renovascular hypertension caused by Takayasu′s arteritis ofthe renal arteries were successfully treated with percutaneoustransluminal angioplasty- There were 9 females and 1 male with mean age of 24-4 years (ranged from 14 to 35 years)- Diagnosis was based on clinical examination such as blood pressure ,laboratory examination and digital subtraction angiography ( DSA) via eitherintravenous or intraarterial approaches- Blood pressure ranged from 260/160 m m Hg to 150/106 m m Hg- One patient had already had contralateral nephrectomy- One patient subsequently underwent contralateral autotransplantation after PTRA on left side- The erythrocyte sedimentationrate ( ESR) was normal in 9 patients and mildly elevated in 1- DSA showed unilateral and bilateral artery stenoses in 6 and 4 , respectively- Three patients associated with mild abdominal aortic stenosis and 5 patients complicated with single artery lesion ofinnominate ,celiac , superior mesentery ,iliac ,and pulmonary artery ,respectively- The blood pressure was measured before and im mediately after the procedure ,and also before discharge- All patients were followed with a mean follow up period of 12-1 years (ranged from 10 ～15-3 years) - Of them , 2 had intravenous DSA (IVDSA) 3 years after PTRA, 1 had intraarterial DSA (IADSA) 8 years after PTRA- Electron beam computed tomography angiography ( EBCTA) and three dimensional reconstruction (3D) were performed in 2 patients 10 years after PTRA- The clinical results of PTRA were evaluated based on the blood pressure response after angioplasty- The patients whose blood pressure was ≤140/90 m m Hg without antihypertensive medications were considered cured ,those of diastolic pressure decreased < 15 % or systolic pressure decreased < 10 % with less antihyperten
