[Percutaneous transluminal angioplasty in the treatment of 79 cases of reno-vascular hypertension].

79 cases of reno-vascular hypertension were treated with percutaneous transluminal angioplasty (PTRA) during 1981-1994. Athrosclerosis as the etiology of renal artery lesions was noted in 14 cases (17.7%), arteritis in 57 (72.2%), and fibro-muscular dysplasia in 8 (10.1%). The success rate of PTRA was 94.8%. The morbidity rate was 3.8%. There was no mortality in this series. The cure-improvement rate after average follow-up of 44.8 months was 73.4%. It was 75.4% in the group of arteritis. We conclude that PTRA should be considered as the first choice for the treatment of renovascular hypertension, especially to the arteritis patients.
