Hemodynamic Effect of Unequal Anterior Cerebral Artery Flow Rates on the Anterior Communicating Artery Bifurcation: A Computational Fluid Dynamics Study

Figure 6

(a) Velocity field during systole and (b) early diastole with ACA flow rates set at . Bifurcation of the A1 parent flow artery into the ACOM and A2 segments is again seen. Left ACA impingement site appears to move even further rightward along A2-ACOM adjoining wall compared to that seen in the case where . Flow separation is again seen on the right A2-ACOM impingement site leading to local recirculation effects.
