The percentage of hemodynamic changes for stent models. E, a single-Enterprise stent model; E2, double-Enterprise stent model; L, a single-LVIS stent model; L2, double-LVIS stent model; P, a single-Pipeline device model. Note: WSS wall shear stress; Histogram respectively shows the hemodynamic parameter (Velocity, WSS and Pressure) changes among E, E2, L, L2, P, P2 compared to Control from left to right. Although the double Pipeline device (PED) demonstrates the most reduction of Velocity and WSS, the double LVIS stent still demonstrate an obvious flow diversion effect than the conventional double Enterprise stent and the single PED. The overall Pressure change is minor after stenting compared to Control
