Blood flow in mildly stenosed aortoiliac bifurcation: A numerical study

Abstract

Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity. Atherosclerosis is a major CVD resulting in stenosis development in the arterial lumen. Computational Fluid Dynamics (CFD) techniques provide a better understanding of the causes of the disease and its early diagnosis. The present study aims at analysing the blood flow in a mildly stenosed aortoiliac bifurcation using the finite volume-based software ANSYS. It is inferred that even a mild stenosis in the arterial bifurcation also affects the flow of blood and hemodynamic parameters like pressure and velocity.
