What is Vascular Stenosis?

Carotid artery disease, also called carotid artery stenosis, is the narrowing of the carotid arteries, usually caused by atherosclerosis. Atherosclerosis is the buildup of cholestero l, fat and other substances traveling through the bloodstream, such as inflammatory cells, cellular waste products, proteins and calcium. These substances stick to the blood vessel walls over time as people age, and combine to . Feb 02,  · Vascular stenosis is a term used to describe the narrowing of blood vessels. Most commonly, blood vessel narrowing occurs as a result of atherosclerosis inside arteries, the vessels which carry blood from the heart to supply the body.

Vascular stenosis is a term used to describe the narrowing of blood vessels. Most commonly, blood vessel narrowing occurs as a result of atherosclerosis inside arteries, the vessels which carry blood from the heart to supply the body. Atherosclerosis, or hardening of the arteries, is a process in which fat, what is a stenosis in artery and other substances build up inside artery walls forming what are called plaques. These atheromatous plaques make the walls of an artery harder and thicker, so stenoxis blood vessel becomes narrower and less flexible, making it more difficult for blood to flow through.

Vascular stenosis typically affects arteries in the brainheart arrery legs and, when severe, causes tissue death, resulting in conditions such as strokes and heart attacks.

The abnormal narrowing of arteries caused by atherosclerosis can affect arteries in the legs, particularly those supplying the calf muscles. This can lead to a condition wjat as intermittent claudication, where, in arterg early stages, cramping pains are felt in the calves after walking a certain distance.

The pain goes away after resting for a few minutes. If the disease progresses, the pain is experienced even while resting and leg ulcersor even gangrene of the toes and feet, may occur. Vascular stenosis of arteries in the heart can lead to a condition called angina, where pain is felt in the chest during exercise.

Again, resting usually causes the pain to go away within a short time, although there is the potential for an artery to become completely blocked. In this case the pain becomes heavy and persistent, possibly spreading to the arm or neck, and a heart attack takes place, in which an area of heart muscle dies off. When arteries in the brain are affected by vascular stenosis, this can shut off the blood supply to part of the brain tissue or lead to the rupture of a small blood vessel, with bleeding into the brain.

Either of these events results in a stroke, where an area of brain tissue dies off, causing a range of possible symptoms including paralysis, numbness, and problems with speech, sight, movement and stenoxis.

Carotid artery stenosis, which is narrowing of the large arteries in the neck, may also reduce how to free recharge in airtel brain's blood supply and lead to a stroke. If the stenosis becomes severe enough to cause a stroke or heart attack, emergency treatment in the hospital will be required. Prevention is important, and progression of stenosis can be halted and the outlook improved by stopping smoking, losing weight, eating more healthily and exercising more.

Medication is available to treat conditions such as angina and intermittent claudication, and surgery is sometimes used to bypass or widen blocked arteries. It is also beneficial to treat any other conditions which tend to make vascular stenosis worse, such as high blood pressure and diabetes.

Aug 24,  · Symptoms of Vertebral Artery Stenosis A vertebrobasilar stroke classically causes vertigo, ataxia and loss of balance. Various cranial nerves can be dysfunctional. Breathing and consciousness may be impaired. Feb 15,  · Coronary stenosis is a condition in which a coronary artery becomes tapered and backed up with materials like fat or cholesterol. A coronary artery is a blood vessel located in the heart that is responsible for providing the heart with blood.

Coronary stenosis is a condition in which a coronary artery becomes tapered and backed up with materials like fat or cholesterol. A coronary artery is a blood vessel located in the heart that is responsible for providing the heart with blood.

If the coronary artery becomes injured somehow, it can result in coronary stenosis. Cholesterol is a solid material that can attach to the insides of blood vessels and affect their ability to carry blood to the heart.

Having high levels of cholesterol in the blood can damage the coronary artery, as can having high blood pressure levels. Smoking can also cause the condition because the nicotine in cigarettes can make blood vessels become narrowed and more susceptible to becoming blocked. Mild instances of stenosis may not have any symptoms. Once the condition becomes worse and the artery becomes more tapered, it can result in a tight feeling in the chest because it has to fight against the clogged materials to pass blood through.

If left untreated, the blood in the artery can clot and completely block it from providing the heart with blood, resulting in a heart attack. Coronary stenosis can be treated with the use of medications. A doctor may prescribe blood thinning medication so blood can more easily get through a constricted coronary artery. If a person has high cholesterol levels, he or she can take medication to lower amount of cholesterol in blood, making it less likely to cause blockage.

Medications to lower blood pressure can prevent stenosis from worsening. The condition can also be treated with surgery. One of the most common surgeries for coronary stenosis is angioplasty , in which a surgeon inserts an unfilled balloon into the clogged area and uses an instrument to fill the balloon with air.

This forces excess materials closer to the walls of the artery, freeing up space for blood to pump through. More serious cases, as when than one artery is clogged, may need bypass surgery. A surgeon cuts a piece of a vein from another body part and attaches it to the blocked area to redirect blood around any narrowed coronary arteries. As a person gets older, he or she is more likely to have coronary stenosis, but the condition may also be hereditary. It is more common in males than females, but can occur in anyone.

Having a sedentary lifestyle or being obese puts a person at a higher risk for developing stenosis. It can be prevented by getting daily exercise, eating a diet low in saturated fats, not smoking, and seeking treatment for high cholesterol or blood pressure. Please enter the following code:.
