Abstract

Renovascular disease includes renal artery stenosis, renovascular hypertension, and azotemic renovascular disease (ischemic nephropathy). Renovascular hypertension is defined as an elevated blood pressure caused by renal hypoperfusion, usually resulting from anatomic stenosis of the renal artery and activation of the renin-angiotensin system. It accounts for 1% to 2 % of all cases of hypertension in the general population and 5.8 % of secondary hypertension, but it plays a major role in treatable causes of hypertension in the young individuals. Although renovascular stenosis is a common and progressive disease in patients with atherosclerosis, it is a relatively uncommon cause of hypertension in patients with mild hypertension. In contrast, renal artery stenosis is more frequent in certain high-risk populations. Early diagnosis of renovascular hypertension and timely implementation of appropriate therapeutic procedures ensures optimum control of blood pressure, prevents ischemic nephropathy progression, and prevents the development of cardiovascular morbidity and mortality in the hypertensive patient population. As with most complex disorders, management decisions must be highly individualized for patients with renovascular disease. It is essential to consider renal arterial disease as one aspect of atherosclerotic disease.
