초록

Aneurysm embolization method using coils has been widely used. When partial blocking of an aneurysm is inevitable, the locations of coils are important since they change the flow patterns inside the aneurysm, which affect the embolization process. We calculated the flow fields inside the partially blocked lateral aneurysm models for different coil locations-proximal neck, distal neck, proximal dome and distal dome. Flow into the aneurysm sac was significantly reduced in the distally blocked models, and coils at the distal neck blocked inflow more effectively comparing to those at the distal dome. This study suggests that the distal neck should be the most effective location for aneurysm embolization.
