What are the carotid arteries?

Carotic Arteries. The human carotid arteries supply the head and the neck with oxygenated blood. The left common carotid artery originates from the aorta and the right common carotid originates from the brachiocephalic artery which originates from the aorta. The carotic artery divides in the neck to form the internal and external carotic arteries.
Supply brain & face. These are the 2 larger arteries in the front of the neck which supply the brain & face. Loss of reduction of supply to brain (clots) blocks blood flow to brain & though most not detected by symptoms, are the bases of most strokes (cva = cerebrovascular events). At the base of the brain, the 2 carotids & 2 vertebral arteries are typically interconnected, circle of willis, offering some protection.

What does having carotid artery disease mean?

Stenosis. Carotid disease is most commonly referred to as a narrowing of the carotid arteries at the bifurcation in the neck. This accumulation of plaque usually occurs in patients with risk factors for peripheral vascular disease such as hypertension, diabetes, hypercholesterolemia and smoking. Plaque is brittle and can cause debris to break off and cause a stroke. Read more...
See below. Carotid artery disease means that the carotid arteries have blockage, usually in the form of atherosclerosis. This is diagnosed with a special ultrasound called a carotid duplex scan. In the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the risk of stroke. Read more...

Hardeningof arteries. Hardening of the arteries may involve carotid arteries. If it progresses it may narrow circulation to the brain or throw off clots to the brain. Symptoms can be transient weakness, numbness, or blindness in one eye or they may be a stroke. If no symptoms, narrowing of the carotid artery of 80% or more means increased risk for stroke and prophylactic surgery may be indicated. Read more...

What happens if someones carotid artery was compressed, how long would it take them to die?

Never. You would induce bradycardia but it wouldn't generally be fatal. (I guess anything is possible), If you pressed on it long enough, you could cause a stroke if the collateral circulation were inadequate. Read more...

What is carotid artery disease?

Carotid stenosis. In the carotid arteries the flow of blood goes from being linear to being turbulent due to the "fork in the road" at the bifurcation. This causes the area of the proximal internal and external carotid arteries to develop plaque. This plaque leads to narrowing of the artery. The material that is causing the narrowing is fragile and can break off and cause a stroke. Read more...
Vascular disease of . Vascular disease of the carotid artery.Perhaps narrowing of the vessel. The disease may lead to a stroke since the brain is not getting adequate blood flow or perhaps a plaque may break off and lodge in a blood vessel in the brain. Read more...
