The carotid arteries (common) bifurcate and become the internal carotid artery (ICA) and the external carotid artery (ECA). Blood supply to the brain is mainly through the internal carotid artery and the vertebral arteries (1). Blood flow to the brain is affected by carotid artery disease. Carotid artery disease is the narrowing (stenosis) or
