Percutaneous transluminal renal angioplasty in aortoarteritis

Percutaneous transluminal renal angioplasty (PTRA) was performed in 26 patients with aortoarteritis, including unilateral renal artery stenosis in ten patients, bilateral renal artery stenosis in 16 patients. The total of 37 stenotic artery were performed by PTRA. Among them, 30 stenosis (81.1 per cent) were technically successful, three stenosis (8.1 per cent) were technically improved, and four stenosis were resistant to dilatation. The blood pressure responses were observed after PTRA, including cured in 17 patients (65.4 per cent), improved in five patients (19.2 per cent), failed in four patients (15.4 per cent). Sixteen patients after successful angioplasty were followed-up from 6 months to 15 years (average 5.4 years). The blood pressure was still normal in 12 patients (75 per cent). The blood pressure gradually increased may be due to restenosis in four patients (25 per cent).
