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; …
Why would stenosis of the carotid arteries have an effect on blood flow to the brain?
Brain cells start to die after just a few minutes without blood or oxygen. If the narrowing of the carotid arteries becomes severe enough that blood flow is blocked, it can cause a stroke. If a piece of plaque breaks off it can also block blood flow to the brain. This too can cause a stroke.
What is an abnormal passage from an internal organ to the skin?
fistula (fistulas, fistulae, pl.) – an abnormal passage or communication from one organ to another or from an internal organ to the body surface; may be caused by disease or injury or created surgically.
What to do for narrowing arteries?
Your doctor inserts a long, thin tube (catheter) into the narrowed part of your artery. A wire with a deflated balloon is passed through the catheter to the narrowed area. The balloon is then inflated, compressing the deposits against your artery walls. A stent is often left in the artery to help keep the artery open.
What causes the arteries to narrow?
Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.

Which of these terms indicate a narrowing of a blood vessel?
The reoccurrence of stenosis, a narrowing of a blood vessel leading to restricted blood flow. Restenosis due to scar tissue occurs in 30 to 50% of patients after they undergo angioplasty, stents, or bypass grafts.
What happens if you have narrow arteries?
Cardiac ischemia is when plaque and fatty matter narrow the inside of your artery so much that it can’t supply enough oxygen-rich blood to your heart. This can cause heart attacks, with or without chest pain and other symptoms. Ischemia happens most during: Eating.
What is the medical term for narrowing of the heart?
[stinō′sis] Etymology: Gk, stenos, narrow, osis, condition. an abnormal condition characterized by the constriction or narrowing of an opening or passageway in a body structure. The term is commonly used to describe heart valve and vessel abnormalities as well as narrowing of joint spaces, as in cervical stenosis.
What causes narrowing of arteries in the brain?
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 the medical term for narrowing of the renal arteries?
pyloric stenosis see pyloric stenosis. renal artery stenosis narrowing of one or both renal arteries by atherosclerosis or by fibrous dysplasia or hyperplasia, so that renal function is impaired (see ischemic nephropathy).

What is narrowing of a vessel?
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, cells and other substances build up inside artery walls forming what are called plaques.
