Abstract

Stent insertion for cerebral aneurysm has been studied using ideal and realistic aneurysms in recent years. Stent insertion aims at reducing the flow in an aneurysm. To minimize the average velocity in an aneurysm, we applied optimization to the strut position in a realistic aneurysm based on computational fluid dynamics. The result shows the effect on velocity reduction of strut placement in the inflow area.
