< i > Emergency Response to Stroke -- The Neural Pathophysiology of Stroke

First, internal carotid artery occlusion in most people is completely asymptomatic, provided that it is not associated with distal embolization of clot.

This is because, in nearly all people, adequate compensation for this loss of blood flow is provided by the anastomotic connections defining the Circle of Willis.

Only when clot propagates or embolizes beyond the Circle of Willis is collateral supply likely to be insufficient.
