Percutaneous transluminal renal angioplasty in aortoarteritis

Percutaneous transluminal renal angioplasty (PTRA) was performed in 26 pati ents 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 c ent) were technically successful, three stenosis (8.1 per cent) were techni cally improved, and four stenosis were resistant to dilatation. The blood p ressure 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 wer e followed-up from 6 months to 15 years (average 5.4 years). The blood pres sure was still normal in 12 patients (75 per cent). The blood pressure grad ually increased may be due to restenosis in four patients (25 per cent). (C ) 1998 Elsevier Science Ireland Ltd. All rights reserved.
