Revascularization may accelerate renal dysfunction in hypertensive patients with moderate atherosclerotic stenosis of renal arteries.

Atherosclerotic renal artery stenosis (ARAS) accounts for more than 90% of cases with renal artery stenosis, which is the recognized cause of secondary hypertension, renal dysfunction and acute pulmonary edema. It is estimated that about 15% of patients with hypertension also have different degrees of ARAS at the same time. Hypertension is known to be associated with the risk of atherosclerotic vascular disease; these two conditions usually co-exist and interact with each other.
