Effect of stenting on flow in sidewall (S) and curved (C) aneurysm models
| Hemodynamic parameter change | Aneurysm Model | |||
|---|---|---|---|---|
| S | C1 | C2 | C3 | |
| Stasis index increase (s) | 69 | 46 | 26 | 14 |
| Inflow momentum reduction (%) | — | 95 | 74 | 20 |
| Impact zone reduction (%) | 61 | 96 | 98 | 56 |
* Data correspond to Figures 2, 5, and 7.
† As an exception, the sidewall model (S) actually experienced an increase of inflow momentum due to an increased pressure drop along the vessel from stent placement under the fixed flow rate condition. The resulting inflow momentum was still significantly lower than in the curved models, untreated or stented, as can be seen in Figure 2.
