Abstract

The purpose of this study was to analyze the hemodynamics in vascular segments from morphologically realistic three-dimensional reconstruction, and to compare the wall shear in compliant vascular segment model and rigid walled model. Cross-sectinal images of the segments of femoral and carotid arteries in several pigs were obtained using intravascular ultrasound (IVUS) imaging. The geometry of these segments was reconstrcuted from the IVUS images at different times in the cardiac cycle and computational meshes were formed. The computed results revealed that the maximum wall shear stress in compliant model was approximate 5-15 percent less than that in rigid model. The fluctuating component of the wall shear was also smaller for the compliant model.
