Research Abstract |
We propose novel evaluation criteria for assessing aortic revascularization surgery from the standpoint of regulatory science using computational fluid dynamics (CFD). In order to know the blood flow distribution in the body, we measured blood flow in the aortic arch of healthy individuals and aortic aneurysm patients by phase-contrast magnetic resonance imaging (PC-MRI). We created human blood vessel models from the MRI images of the aortic arch, and simplified branch models that represent the vessel geometry after revascularization. We used the models to examine the CFD boundary conditions corresponding to PC MRI images and established a method to analyze blood flow distribution. We also examined the computational limitations of our simplified models.
