Renal artery stenosis (RAS) and atherosclerotic RAS (ARAS) induce similar hypertension and stenotic-kidney dysfunction.
Swine ARAS magnifies loss of stenotic-kidney cortical microvessels.
Cortical hypoxia and fibrosis do not correlate with micro vascular loss in RAS.
In swine, ARAS determinants additional to RAS alone contribute to cortical injury.
