Hemodynamic Effect of Unequal Anterior Cerebral Artery Flow
Rates on the Anterior Communicating Artery Bifurcation: A Computational
Fluid Dynamics Study
Figure 5
(a) Velocity field during systole and (b)
early diastole with ACA flow rates set at .
Again bifurcation of the A1 parent flow artery into the ACOM and A2 segments is
seen. Left ACA impingement site moves 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.
