| Research Abstract |
The influences of the cerebral aneurysm location relative to its parent artery and the stent rotation angle in endovascular treatments with a flow diverter-type stent on inflow into aneurysm were examined using 3D geometric modeling and computational fluid dynamics techniques. In the former examination, the inflow into aneurysm was elevated for the cerebral aneurysm located laterally to the parent artery path due to a secondary flow effect. In the later examination, a striking change in the inflow into aneurysm via local alterations of flow field was observed in a certain combination of the cerebral aneurysm location and the stet rotation angle, regardless of small changes in the aperture ratio with varying angles of stent rotation.
