The carotid artery is the large vertical artery in red. The blood supply to the common carotid artery starts at the arch of the aorta (left) or the subclavian artery (right). The common carotid artery divides into the internal carotid artery and the external carotid artery. Plaque often builds up at that division, and a carotid endarterectomy ...
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]
Carotid artery stenting is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. It is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky.
The concept was first introduced by Bailey [2] in the 1950s prior to the advent of coronary artery bypass surgery to help patients with angina and coronary artery disease. It is still used today when coronary artery bypass surgery proves difficult. Livesay [3] in Texas and Nair [4] in Leeds have published the largest series in the world.

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.
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 external carotid artery arises from the common carotid artery just inferior to the upper border of the thyroid cartilage. [1] At its origin, this artery is closer to the skin and more medial than the internal carotid, and is situated within the carotid triangle.
