The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]

Carotidynia is a syndrome marked by soreness of the carotid artery near the bifurcation. Carotid stenosis may occur in patients with atherosclerosis. The intima-media thickness of the carotid artery wall is a marker of subclinical atherosclerosis and it increases with age and with long-term exposure to particulate air pollution. [9]
The proximal part of left subclavian is blocked (shaded artery). This prevents antegrade ("forward") flow to the left arm and left vertebral. As a result, flow in the left vertebral is retrograde ("backwards") towards the left arm. Flow to the brain and circle of Willis is via antegrade right and left carotid and right vertebral arteries.

The internal carotid artery is an artery in the neck which supplies the anterior and middle cerebral circulation. [ 1 ] In human anatomy, the internal and external carotid arise from the common carotid artery , where it bifurcates at cervical vertebrae C3 or C4.
Rotational vertebral artery syndrome (sometimes referred to as Bow Hunter's Syndrome) results from vertebral artery compression on rotating the neck. [7] The commonest cause is a bone spur from a cervical vertebra, in combination with disease in the opposite vertebral artery. Rotational vertebral artery syndrome is rare.
Carotid agenesis is a vascular anomaly in which the carotid artery, normally present in the neck, does not develop during embryogenesis. [1] The common carotid artery splits into the external carotid artery and internal carotid artery, with the internal carotid artery supplying blood flow to areas of the brain.
Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means the ...
