Carotid artery disease
Carotid stenosis; Stenosis - carotid; Stroke - carotid artery; TIA - carotid arteryCarotid artery disease causes the carotid arteries to become narrowed or blocked. The carotid arteries provide part of the main blood supply to your brain. They are located on each side of your neck. You can feel their pulse under your jawline.

Arterial tear in internal carotid artery
Cholesterol may build-up in the lining of an internal carotid artery.

Atherosclerosis of internal carotid artery
The build-up of plaque in the internal carotid artery may lead to narrowing and irregularity of the artery's lumen, preventing proper blood flow to the brain. More commonly, as the narrowing worsens, pieces of plaque in the internal carotid artery can break free, travel to the brain and block blood vessels that supply blood to the brain. This leads to stroke, with possible paralysis or other deficits.

Carotid artery anatomy
There are four carotid arteries, two on each side of the neck: right and left internal carotid arteries, and right and left external carotid arteries. The carotid arteries deliver oxygen-rich blood from the heart to the head and brain.

Coronary artery disease
The coronary arteries supply blood to the heart muscle itself. Blood supply through these arteries is critical for the heart. Coronary artery disease usually results from the build-up of fatty material and plaque, a condition called atherosclerosis. As the coronary arteries narrow, the flow of blood to the heart can slow or stop, causing chest pain (stable angina), shortness of breath, heart attack, or other symptoms.

The right coronary artery supplies blood from the aorta to the right side of the heart.

Carotid duplex
Carotid duplex is an ultrasound procedure performed to assess blood flow through the carotid artery to the brain. High-frequency sound waves are directed from a hand-held transducer probe to the area. These waves bounce off the arterial structures and produce a 2-dimensional image on a monitor, which will make obstructions or narrowing of the arteries visible.

Carotid dissection
Stroke is defined as a loss of brain function due to blocked blood circulation to the brain. Strokes may be caused by a narrowing, obstruction, or leak in the lining of the carotid. This leaking of blood into the artery wall (dissection) may cause a clot to form, reducing blood flow and raising the risk of a stroke. The leak may arise from an injury to the neck, which means stroke secondary to carotid dissection may occur in young people as well as older people.

Carotid stenosis - X-ray of the left artery
A carotid arteriogram is an x-ray study designed to determine if there is narrowing or other abnormality in the carotid artery, a main artery to the brain. This is an angiogram of the left common carotid artery (both front-to-back and side views) showing a severe narrowing (stenosis) of the internal carotid artery just beyond the division of the common carotid artery into the internal and external branches.

Carotid stenosis - X-ray of the right artery
This is an angiogram of the right carotid artery showing a severe narrowing (stenosis) of the internal carotid artery just past the carotid fork. There is enlargement of the artery or ulceration in the area after the stenosis in this close-up film. Note the narrowed segment toward the bottom of the picture.
