| Outline of Final Research Achievements |
Subarachnoid hemorrhage is a catastrophic event and directs to high mobility and bad prognosis. To prevent this event, it is required to verify the pathogenesis. Hemodynamic stress is one of the initiating factors for cerebral aneurysmal formation. We hypothesized that additive hemodynamic change accelerates the development of aneurysms and studied the hypothesis. Ten-weeks-old Sprague-Dawley female rats were additively occluded in Rt.PPA and Rt.ECA. Their rupture incidence and the rupture rate were increased. The development of aneurysms at the circle of Willis may be partly attributable to hemodynamic change. Using this model we will study the efficacy of pharmacological treatment such as telmisartan, eplerenone or cilostazol. On the other hand, we started the clinical studies to assess the pharmacological treatment of cerebral aneurysms.
