[Results of surgery and percutaneous transluminal angioplasty in renovascular hypertension].

The results of the treatment with surgery and percutaneous transluminal angioplasty of the renal artery were evaluated in 63 adult patients of both sex, from 16 to 60 years old with renovascular hypertension due to fibromuscular dysplasia in 48 and to atherosclerosis in 15. The stenosis of the renal artery was unilateral in 47 patients and bilateral in 16. The surgical procedures more used were the aorto-renal bypass with saphenous vein in 22 patients and unilateral nephrectomy in 16. From 41 patients treated with surgery, the arterial hypertension was cure or improved after one year in 30 (73.1%). From 22 patients treated with angioplasty, cure or improved was obtained in 17 (77.2%). Satisfactory results were obtained in patients with fibromuscular dysplasia and unilateral stenosis, and poor results in atherosclerosis and bilateral stenosis, with both methods. It is concluded, that surgery and angioplasty are satisfactory therapeutic methods in the renovascular hypertension, principally when is unilateral and due to fibromuscular dysplasia.
