Abstract

Abstract

The effects of renal artery stenosis (RAS) on blood flow and vessel walls were investigated. Pulsatile blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT-scan images was simulated, incorporating fluid-structure interaction (FSI). In addition to the investigation of RAS effects on wall shear stress and displacement of vessel wall, it was determined that RAS lead to decrease in renal mass flow which may cause the activation of the renin-angiotension system and result in severe hypertension.
