Fig 1.
Generated basic aneurysm models and parent artery.
The stent was deployed in the region of the green centerline. Five types of aneurysms (Small, Medium, Medium-Large, Large, and Giant) were generated by varying aneurysmal height, width, and neck length.
Fig 2.
Generated 6 types of deployed stents.
The Stents were generated by varying the number of wires and wire pitch, and the wire density was calculated.
Table 1.
Number of wires, stent pitch, and wire mesh density for each modeled stent type.
Fig 3.
Streamlines before and after stent deployment in each aneurysm size and stent wire mesh density.
The streamlines are sampled from the second systole and colored in the range of 0–0.1 m/s according to the velocity.
Fig 4.
Relationships between each parameter relative change and stent wire mesh density.
The range of relative change over the second pulsation observed in unsteady flow simulation are shown in whiskers. A) Results of relative change of velocity (RC-V). B) Results of relative change of volume flow rate (RC-VFR). C) Results of relative change of pressure (RC-P). D) Results of residual volume ratio (RVR).
Fig 5.
Pressure on aneurysmal surface before and after stent deployment for each aneurysm size and stent wire mesh density.
The wall of aneurysms is sampled from the second systole and colored according to the pressure.
