TABLE 2. Aneurysmal flow parameters in the unstented and stented models.
Sequence | Model | Average WSS (%) |
Elevated WSS Area (%) |
Low WSS Area† (%) |
Average Velocity Magnitude (%) |
Turnover Time (%) |
Pressure Reduction†† (mmHg) |
---|---|---|---|---|---|---|---|
Unstented | U | 100 | 100 | 0.11 | 100 | 100 | 0.00 |
Single stent | E | 85.9 | 81.6 | 0.25 | 84.9 | 113.8 | 0.99 |
V | 85.1 | 73.0 | 0.18 | 84.6 | 117.1 | 1.43 | |
Double stent | E2 | 71.3 | 75.6 | 2.20 | 73.6 | 127.2 | 1.47 |
EV | 69.2 | 54.8 | 0.81 | 71.2 | 128.5 | 1.94 | |
Triple stent | E3 | 54.7 | 37.6 | 1.32 | 61.9 | 141.0 | 1.85 |
All parameters are expressed as percentages of the unstented case, except for the Low WSS Area† and Pressure Reduction††.
Given as a percentage of the entire aneurysm sac area. Low-level WSS was defined as WSS <0.1 times the average value in the parent vessel.
Given as the pressure drop from the unstented case.
