Outline of Final Research Achievements

Hemodynamic factors play a crucial role in the rupture of intracranial aneurysm, subarachnoid hemorrhage (SAH). We examined hemodynamic characteristics based on computational fluid dynamics (CFD) analysis, and evaluated their relationships with the severity of SAH. We classified 16 internal carotid artery aneurysms presenting with SAH into mild group and severe group. We classified aneurysms into 3 types based on the relationship between flow pattern and rupture point. Type 1: rupture point exists along main flow, type 2: rupture point is related to disturbed flow, type 3: rupture point exists at a distance from main flow. We detected types of flow patterns related to severe group, and evaluated hemodynamic parameters at the rupture point. Type 1 and 2 were correlated with severe group, and type 3 was correlated with mild group.
