RESUMO
PURPOSE--To report the experience in the treatment and long-term follow-up of patients with renovascular hypertension submitted to angioplasty and/or surgical revascularization, and to compare blood pressure and renal function responses to both treatment. METHODS--One hundred and twenty-four patients diagnosed with renovascular hypertension, divided, according to the etiology, as atherosclerosis (76 patients), fibromuscular dysplasia (32) and arteritis (16), were submitted to isolated or associated treatment of renal revascularization by percutaneous transluminal angioplasty (71 patients) or surgery (84). The patients were followed-up during 2.5 +/- 1.5 years and we evaluate blood pressure response and renal function preservation. In relation to blood pressure control, the patients were considered as cured when normotensives without antihypertensives, improved when normotensives with fewer drugs than previously, and unchanged, when out of these criteria. RESULTS--From 124 patients, 20 per cent were considered cured, 54 per cent improved and 26 per cent unchanged, after a mean follow-up of 2.5 +/- 1.5 years. Patients with atherosclerosis and fibromuscular dysplasia presented a higher rate of care and improvement after surgery. The blood pressure and the number of antihypertensive drugs decreased significantly during the follow-up among patients that cured or improved arterial hypertension, either after angioplasty (190 +/- 26/115 +/- 14 mmHg vs 130 +/- 34/85 +/- 7 mmHg. 2.70 vs 1.60 drugs) or after surgery (194 +/- 17/115 +/- 16 mmHg vs 143 +/- 18 mmHg vs 88 +/- 8 mmHg, 1.88 vs 1.51 drugs). It was also observed a significant decrease of serum creatinine among these patients. CONCLUSION--Renal revascularization in patients with renovascular hypertension, either by angioplasty or surgery, is beneficial to control blood pressure and to preserve renal function in the majority of patients
