What is occlusive stenosis?
Carotid occlusive disease, also called carotid stenosis, is a condition in which one or both of the carotid arteries becomes narrowed or blocked. It is a serious condition that increases the risk of stroke if left untreated.
How serious is vascular stenosis?
When this hardening occurs, the blood vessel experiences a narrowing that can make it more difficult for the blood to flow. This is what is referred to as vascular stenosis, and it affects the blood vessels leading to the brain, heart, and legs most often.
Is carotid stenosis a cardiac disease?
The narrowing is caused by atherosclerosis. This is the buildup of fatty substances, calcium, and other waste products inside the artery lining. Carotid artery disease is similar to coronary artery disease, in which buildup occurs in the arteries of the heart and can cause a heart attack.
Does stenosis mean blockage?
When an artery inside the skull becomes blocked by plaque or disease, it is called cerebral artery stenosis. Arteries anywhere in the body can become blocked. For example, carotid artery stenosis is a narrowing of the large artery in the neck, the carotid, that supplies oxygen-rich blood to the brain.
Which symptom is noted with occlusive arterial disease?
Claudication is the most common symptom of lower extremity arterial occlusive disease. Some people may also experience numbness, weakness, or cold in the feet or legs. As the disease progresses, pain may also be felt at rest in the toes.
How is vein stenosis treated?
Balloon angioplasty is the therapy of choice for symptomatic venous stenosis. Venous access can be established via the antecubital vein, dialysis fistula, or common femoral vein. Conservative balloon sizing should be adopted at the start because these vessels have less muscular tissue than the arterial system.
What causes vascular stenosis?
In the context of stroke, “stenosis” is usually caused by atherosclerosis, a condition where a blood vessel supplying blood to the brain is narrowed due to fatty deposits, known as plaques, on the vessel’s inside wall. Risk factors for this type of stenosis include high blood pressure and high cholesterol.
