title: [Renovascular hypertension--clinical observations and long-term follow-up].
abstract: Renovascular hypertension is one of the most common causes of secondary hypertension. Its early diagnosis is particularly important, firstly because it is one of the few potentially reversible causes of chronic renal failure. In many centers, including our own, renal angioplasty (PTA) or surgery is the treatment of choice for patients with renovascular hypertension. The aim of the study was the evaluation of the early and late results of PTA versus renovascular surgery. The diagnostic procedures and clinical course of renovascular hypertension were also analyzed. Among patients with renovascular hypertension treated in our Department during the 1981-1993 years, 89 patients (46 men, 43 women) were diagnosed and having renovascular hypertension (3% of all hypertensive patients). The average duration of hypertension in this group was 5 years. High incidence of accelerated hypertension (18%) and cardiovascular complications were observed: myocardial infarction in 20.2% of cases and stroke in 4.5%. The presence of renal failure was found in 22.5% of cases, hypokalemia in 11.2%, 38.3% of patients had changes in other arteries. Renal angioscintigraphy and captopril renal scintigraphy were performed in accordance with renal arteriography in 80% of patients. Arteriography showed unilateral renal artery stenosis in 78.7% of patients and bilateral - in 21.3%. The most common cause of renovascular hypertension in our material was atherosclerosis (65.2%). Fibromuscular dysplasia and Takayasu arteritis were diagnosed less frequently (25.8% and 9.0% respectively). Forty four patients were treated with PTA, 15 underwent surgical revascularization and 11 - unilateral nephrectomy. Early beneficial therapeutic effect (normalization or improvement of blood pressure control) was observed in 88.6% for PTA and 66.7% for surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
