ABSTRACT
Renovascular hypertension due to renal artery occlusive disease is the most common cause of secondary hypertension (1, 2). Its prevalence in both the general population and the hypertensive population is not known precisely, with estimates ranging from 0.18 (3) to 5% (4, 5) of the hypertensive population to 3% of the general population (6). Renal artery occlusive disease may be responsible for up to 16% of patients with end-stage renal disease, and its prevalence appears to be increasing (7). The vast majority of renal artery occlusive disease causing hypertension is due to atherosclerosis, ranging from 67 to 97.8% (8-12).
