| Outline of Final Research Achievements |
Intracranial aneurysm (IA) flow was visualized by using in vitro flow simulator and particle image velocimetry (PIV), to propose embolic index of IA treatment. In the result, it was considered that IA with smaller dome size and wider neck width aneurysms were more difficult to embolize by stent-sheilding. It was considered that IA with sharp bend parent vessel was difficult to embolize. And, shielding performance of stent devices were compared. Shielding performance of our developed microporous covered stent was superior to bare stent and flow diverter. It is expected that this measurement method is useful to evaluate difficulty of aneurysm embolization and shielding performance of stent.
