    Abstract:
    In order to evaluate the late results of reconstructive surgery for renovascular hypertension, a review was made on a series of 120 consecutive patients who underwent operations over a 11 year period. There were 82 males (68.3%) and 38 females (31.7%) with a mean age of 48.4 years. Renal artery by-pass grafts were used in 90% (120/133), a thromboendarterectomy in 5.2% (7/133), and other surgical procedures were performed in 4.8% (6/133). Associated vascular procedures were performed in 38.3% (46/120) of patients. Operative mortality was 2.5% (3/120) overall; there was no mortality in the isolated renal artery reconstructions. There was a clinical success (after a mean follow-up of 48 months) in 80.4% of patients. The most important factors influencing clinical result after renal revascularization were: a generalized atherosclerosis (p less than 0.05), duration of hypertension (p less than 0.01) and the early post-operative response of the blood pressure (p less than 0.01). The overall five- and ten-year actuarial survival probabilities were 85 and 68%, respectively. The most common causes of death were myocardial infarction, stroke and cancer. Cox regression analysis for variables influencing survival indicated that persistence of severe hypertension was the major determinant of late survival (p less than 0.05). Hypertension in females is better tolerated, while younger patients appear to have better results and late survival after surgical treatment.
