Approximately 90% of renal artery stenosis cases occur due to progressive atherosclerosis. The ostium and proximal third of the renal arteries are the most commonly involved regions in atherosclerosis. Nonetheless, segmental and diffuse atherosclerosis may still be seen in the minority of patients, especially in context of chronic kidney disease and poor renal survival. | |||

Overview
Renal artery stenosis is defined as the unilateral or bilateral progressive narrowing of the renal arteries or their branches of more than 50% in diameter.[1] It is a heterogeneous group of diseases that most commonly include: fibromuscular dysplasia (FMD) and atherosclerotic renal artery stenosis (ARAS). Although renal artery stenosis may be an isolated asymptomatic condition, it may commonly lead to secondary hypertension and ischemic nephropathy, and chronic renal insufficiency.[2][3]
Approximately 90% of renal artery stenosis cases occur due to progressive atherosclerosis. The ostium and proximal third of the renal arteries are the most commonly involved regions in atherosclerosis. Nonetheless, segmental and diffuse atherosclerosis may still be seen in the minority of patients, especially in context of chronic kidney disease and poor renal survival.
