| Outline of Final Research Achievements |
The purpose of this study was to build a large-scale cerebral aneurysm database including computational fluid dynamics (CFD) analysis, and to predict wall property and rupture risk. In the 3 years around 500 cases were included. Based on the database, we reported that the yellowish wall can be predicted by CFD. In addition, we revealed that rupture risk or recanalization after coil embolization could be predicted by CFD.
Further analysis based on the database and outpatient clinic system are planned.
