Outline of Final Research Achievements |
Flow diversion surgery, either direct or catheter-based approach, has substantial risks despite its outcome is not unexpectable. To develop a measure to predict the outcome of flow diversion surgery, the aneurysm flow dynamics before and after virtual flow diversion surgery using computer simulation. Seven cases were subjected in this study during the study period. Focal elevation of wall shear stress or pressure may appear on the aneurysm wall after flow diversion surgery, which might have resulted in the rupture of the aneurysms after the flow diversion surgery. The comparison of the simulation results to the clinical outcome will prove the validity of the fluid dynamic simulation of flow diversion surgery.
