  Carotid artery - Wikipedia, the free encyclopedia
The carotid artery is a major artery of the head and neck.
The left carotid arises from the arch of the aorta, while the right carotid arises as one of the branches of the bifurcation of the brachiocephalic artery (trunk) into the carotid and right subclavian artery.
The latter two could be considered a terminal bifurcation of the artery; the maxillary artery is the larger of the two.

 Carotid Endarterectomy   (Site not responding. Last check: 2007-10-07)
Carotid Endarterectomy is the name of the operation to clean out the artery to the brain.
The carotid artery in the neck is prone to the development of atheroma which is the name for the collection of fat and calcium which narrows arteries in the body.
The artery is closed with a Dacron patch to prevent narrowing it, and blood is supplied to the brain during the operation via a plastic shunt.

 Carotid endarterectomy for TIA and stroke
Carotid endarterectomy is surgery to remove plaque buildup in the carotid arteries.
Carotid endarterectomy is 3 times more effective than treatment with medicine alone in preventing stroke for people who have symptoms that can be attributed to a 70% to 99% blockage of the carotid arteries.
Tests such as carotid ultrasound, carotid arteriography, CT angiography, or magnetic resonance angiography (MRA) are needed before surgery to evaluate the amount of plaque buildup in the carotid arteries and the flow of blood through the narrowed area.

The carotid arteries are the four principal arteries of the neck and head.
They have two specialized regions: the carotid sinus, which monitors the blood pressure, and the carotid body, which monitors the oxygen content in the blood and helps regulate breathing.
At the base of the brain, the two internal carotids and the basilar artery join to form a ring of blood vessels called the "circle of Willis." The external carotid arteries have several branches which supply the tissues of the face, scalp, mouth and jaws.

 Carotid Artery Disease -- From WebMD
There are two carotid arteries (one on each side of the neck) that supply blood to the brain.
The carotid arteries supply the large, front part of the brain, which is responsible for our personality and our ability to think, speak and move.
Like the arteries that supply blood to the heart (the coronary arteries), the carotid arteries can also develop atherosclerosis, the build-up of fat and cholesterol deposits, called plaque, on the inside of the vessels.

Carotid artery disease is a type of cerebrovascular disease that affects the vessels leading to the head and brain.

 Carotid Occlusive Disease
The carotid arteries are paired arteries in the neck that serve as the major blood supply to the brain. The major risk factors for carotid artery occlusive disease include atherosclerosis or “hardening of the arteries” elsewhere in the body, a history of smoking, diabetes, and high cholesterol levels.
When the patient’s history or physical examination suggests potential carotid artery narrowing, the patient is generally sent for a noninvasive imaging study to evaluate the carotid arteries. These studies may include a duplex ultrasound study or a magnetic resonance angiogram. Both are completely noninvasive and highly accurate tests to determine the presence and extent of carotid artery narrowing.
When a carotid artery narrowing of greater than 80 percent is found, consideration for repair of the artery is appropriate. Patients who have had warning signs for stroke and are found to have significantly narrowed carotid arteries are recommended for artery repair.

Stroke secondary to carotid stenosis occurs when a major portion of one or both carotid arteries (the arteries in the neck that supply blood to the brain) is narrowed or blocked.
In atherosclerosis (hardening of the arteries), fatty deposits occur in the inner lining of the arteries, and atherosclerotic plaque (a mass of fatty deposits and blood platelets) develops.
Carotid endarterectomy, surgical removal of plaque from the carotid arteries, may be indicated to prevent new strokes from occurring, especially if there is more than 70% of the carotid artery occluded and there are no contraindications (reasons against the surgery) such as coexisting terminal illness or dementia.

 Carotid Artery Disease and Stroke
There are two smaller arteries, the vertebral arteries, which run through the spine and supply blood to the back part of the brain (the brainstem and cerebellum).
The carotid arteries supply the much larger front part of the brain, where thinking, speech, personality and sensory and motor functions reside.
As the carotid arteries narrow, the blood flow to the brain diminishes.

This study was designed to refine this association and determine whether the severity of atherosclerosis in the carotid arteries correlated with the severity of coronary heart disease, according to the study's lead author, Ioannis Kallikazaros, M.D., associate director in cardiology at Hippokration Hospital in Athens, Greece.
Researchers found that severe atherosclerosis in the carotid arteries was related to severe coronary heart disease.
The carotid artery classifications were: 1) no sign of plaque; 2) 2 to 15 percent artery obstruction; 3) 16 to 49 percent artery obstruction; 4) 50 to 79 percent artery obstruction; and 5) 80 to 100 percent artery obstruction.
