1 Flow patterns of 2 vertebral artery fusiform cases with different stent-placement strategies.
Flow patterns of 2 vertebral artery fusiform cases with different stent-placement strategies. One and 2 represent 2 individual cases. From left to right, flow patterns before and after implantation of 1–3 stents. The yellow dotted lines represent the positions of the stents. As the number of stents increased, blood flow inside the stent lumen concentrated and the flow rate accelerated, while the flow rate inside the aneurysmal sacs slowed and the vortex intensity weakened.
