초록

Angiography has excellent advantages to visually observe the internal morphology of the stenosed blood vessel. For OCT(Optical coherence tomography), it is possible to directly provide a reliable two-dimensional cross-sectional information as compared to conventional angiography. In the present study, both velocity and wall shear stress distributions were numerically investigated using stenosed blood vessel models (0%, 25%, 50%, and 75% stenotic expansion rate). The blood vessel geometry was prepared based on the human stenotic aorta from OCT image. Commercially available software (CATIA V5) was used to reconstruct 3D blood vessel for numerial analysis. Pulsatile blood flow boundary condition was applied. The numerical study could help our understanding of the hemodynamic differences in a stenosed blood vessel.
