![]() The position, size and shape are suggestive of either the internal or external carotid artery. There are several observations that will help you identify the arteries. 8.2 Which morphologic clues help to distinguish the internal- from the external carotid artery? A plaque or stenosis of the external carotid artery usually has little consequence (unless the external carotid artery provides collateral flow). Therefore ischemia or an embolic event will only occur if the internal carotid artery is involved. The internal carotid artery supplies the brain while the external carotid artery supplies extracranial structures of the head and neck. It can make quite a difference to the patient if a stenotic lesion or a plaque is located in the internal or external carotid. One of the most frequently asked questions, in carotid ultrasound is: “how can I tell if the vessel I am imaging is the internal- or the external carotid artery?" Especially, since the location of the vessels (and their relationship to each other) vary greatly. Only the internal carotid arrteries and the vertebral arteries feed blood to the brainĨ.1 Why is it important to differentiate the internal- from the external carotid artery with ultrasound?
