Numerical Analysis of The Relationship Between Hemidynamic Force on and Internal Stress in Cerebal Aneurysms

Abstract

Image-based numerical fluid-structure interaction analyses are performed to investigate the relationship between hemodynamic force, which is known to affect vascular diseases, and stress in arterial wall. Tensile stress in aneurysmal wall is calculated near bleb, which is said to be one of risk factor of rupture of aneurysm. The relationship between hemodynamic force on and stress in aneurysmal wall obtained in this study can explain the process of rupture of aneurysm.
