What is a stenotic vessel?
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.
What is stenosis of the heart vessels?
Aortic valve stenosis — or aortic stenosis — occurs when the heart’s aortic valve narrows. The valve doesn’t open fully, which reduces or blocks blood flow from your heart into the main artery to your body (aorta) and to the rest of your body. Your treatment depends on the severity of your condition.
What causes vessel stenosis?
More than 90% of the time, renal artery stenosis is caused by atherosclerosis, a process in which plaque made up of fats, cholesterol, and other materials builds up on the walls of the blood vessels, including those leading to the kidneys.
What is the difference between thrombosis and stenosis?
Stenosis and thrombus formations are the result of vascular injury and inflammation due to vascular cell dysfunction, resulting in any of the following pathological or healing injury responses: an initial coagulation/thrombus (blood clot) on the vascular inner wall to promote healing or further injury and inflammation; …
What is the medical term for narrowing of a blood vessel?
Stenosis. The abnormal narrowing of a blood vessel leading to restricted blood flow, often caused by atherosclerosis or plaque buildup.
Can renal artery stenosis be cured?
Unlike treatment of fibromuscular dysplasia, cure of atheromatous renal artery stenosis by angioplasty alone is rare. Most atheromatous renal artery stenosis is due to aortic plaques encroaching on the ostium of the renal artery.
What is the medical term for vessel?

Which is an example of a vascular stenosis?
Examples of vascular stenotic lesions include: Intermittent claudication(peripheral artery stenosis)
What does stenosis stand for in medical terms?
A stenosis (from Ancient Greek στενός, “narrow”) is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a stricture (as in urethral stricture).
What is the medical term for aortic stenosis?
aortic stenosis. Stenosis of blood flow from the left ventricle to the aorta due to aortic valve disease or obstructions just above or below the valve. The stenosis may be congenital or secondary to diseases of adolescence or adulthood, e.g., rheumatic fever or fibrocalcific degeneration of the valve.
