Effect of stenting on flow in sidewall (S) and curved (C) aneurysm models

Hemodynamic parameter changeAneurysm Model
Stasis index increase (s)69462614
Inflow momentum reduction (%)957420
Impact zone reduction (%)61969856
  • * 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.
