| Outline of Final Research Achievements |
We analyzed the factors that related to the increase in the size of the cerebral aneurysm and the formation of intra-aneurysmal thrombosis using the technique of computed fluid dynamics (CFD) and computer aided design (CAD) techniques. Then we verified the results of these factors by the well controlled animal experiments of giant aneurysm model. Although there are some factors suggested to be related to the increase in size of cerebral aneurysm, such as the blood velocity at the neck of aneurysm or the wideness of the aneurysm base, this study could not clarify the significant factor that related to the extensive growth of the aneurysms in the animal experiments. By applying the current research results to the real clinical practice, it is expected that the outcome of the treatment for large or giant cerebral aneurysm will improve.
