Under normal conditions, blood flow in the communicating arteries is negligible. However, if a subject has an incomplete circle of Willis, e.g., is missing one of the main arteries or communicating arteries or is under pathological conditions such as complete or partial occlusion of one of the cerebral or carotid vessels, the flow can be redirected to perfuse deprived areas [25, 26].
