[Renovascular hypertension: results of surgical treatment with a three-year follow-up (author's transl)].

: Between 1966 and December 1979, 58 patients with renovascular hypertension were surgically treated at our center. Follow-up was a minimum of one year in all patients and in all cases permeability of revascularization was assessed through angiography from one to six months after surgery. The mean follow-up was 39 months. Thirty-eight (65.5%) were male and 20 (34.6%) female. Age of onset was between 3 and 53 years (mean 36.3 years). Etiology was arteriosclerotic in 27 cases and fibrous dysplasia in all its manifestations in another 27, in 2 cases vascular compression due to retroperitoneal fibrosis and renal hypoplasia in the remaining two. In 4 cases lesions were bilateral. The cure rate was 37 patients (63.8%), Improvement in 16 (27.6%), while there was no improvement in 5 (8.6%). Surgical mortality rate was nil. The different techniques used, indications, long and short term complications and different results according to etiology are discussed.
