Hemodynamic Effect of Unequal Anterior Cerebral Artery Flow
Rates on the Anterior Communicating Artery Bifurcation: A Computational
Fluid Dynamics Study
Figure 3
Velocity field with equal left and right ACA
flow rates () during (a) systole and (b) early diastole. A
dead zone in the ACOM exists throughout the pulsation cycle. (b) Unsteadiness
exists bilaterally at the A2-ACOM impingement sites with flow separation and
vortices seen during the diastolic phase.
