换一批Effects of renal artery stenosis on realistic model of abdominal aorta and renal arteries incorporating fluid-structure interaction and pulsatile non-Newtonian blood flow
摘要The effects of the renal artery stenosis (RAS) on the blood flow and vessel walls are investigated.The pulsatile blood flow through an anatomically realistic model of the abdominal aorta and renal arteries reconstructed from CT-scan images is simulated,which incorporates the fluid-structure interaction (FSI).In addition to the investigation of the RAS effects on the wall shear stress and the displacement of the vessel wall,it is determined that the RAS leads to decrease in the renal mass flow.This may cause the activation of the renin-angiotension system and results in severe hypertension.
