Presentation transcript:

In a more severe dissection there can be complete occlusion of the internal carotid artery. The patient above has a normal common carotid artery (CCA) and external carotid artery (ECA). The internal carotid artery (ICA) has a proximal injury that has led to complete occlusion of the distal ICA.
