Common Carotid Artery Occlusion With Retrograde Flow in the Internal Carotid Artery: A Case Report

摘要

In most cases of common carotid artery (CCA) occlusion, the internal carotid artery (ICA) is also occluded. This case presents a patient with a patent ICA distal to a thrombotic CCA occlusion, likely secondary to cardiac embolization related to chronic atrial fibrillation, with retrograde filling of the extracranial ICA via intracranial collateral flows.
