Endovascular stent implantation is used for treating cerebral aneurysms by reducing flow in the cavity and the evaluation of stent will be performed by measurements of flow speed. The impact of stent on the blood flow may depend on the design of stent strut. In this study, two stents (Stent A has larger slit and bigger diameter of the strut than Stent B) with similar geometries were prepared. The inflow zone was created at the distal neck and the zone of Stent B included the stent struts, whereas the inflow zone of Stent A was in their two struts. The flow speed measured by SVC method exhibits the speed of stent B was decreased, while that of Stent A was higher than no stent. The capability of the stent for reducing flow into the cavity will depend on the strut diameter and the opened cell on the inflow zone.
