Renal Artery Stenosis In this article. Renal artery stenosis is a narrowing of arteries that carry blood to one or both of the kidneys. Most often seen in older people with atherosclerosis (hardening of the arteries), renal artery stenosis can worsen over time and often leads to hypertension (high blood pressure) and kidney damage.

- Peripheral vascular disease (PVD), or atherosclerosis of peripheral vessels, is the most common cause of symptomatic stenosis in the human vascular tree. The pathogenetic mechanisms that lead to PVD are similar to those of coronary artery disease (CAD).

Foraminal narrowing overview Foraminal narrowing, or foraminal stenosis, is a condition of the spine that can cause pain and other symptoms resulting from spinal nerve root compression. At every level of the spine, a pair of nerve roots runs through the spinal column via small openings called foramina (singular: foramen).oraminal narrowing, or foraminal stenosis, is a condition of the spine that can cause pain and other symptoms resulting from spinal nerve root compression.

Intracranial artery stenosis This narrowing of the blood vessels causes decreased blood flow to the area of the brain that the affected vessels supply. There are three ways in which intracranial artery stenosis can result in a stroke: Plaque can grow larger and larger, severely narrowing the artery and reducing blood flow to the brain. Plaque can eventually completely block (occlude) the artery.

Renal artery stenosis Renal artery stenosis is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.Possible complications of renal artery stenosis are chronic kidney disease and coronary artery disease.his narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.

- However, your feedback is important to us. Carotid stenosis, or carotid artery disease, is a narrowing or blockage of the carotid arteries. Located in the side of your neck, your left and right carotids are two large arteries that carry oxygen-rich blood to your brain.

- In pulmonary stenosis, the flow of blood from the right ventricle to the pulmonary artery is obstructed by narrowing at the pulmonary valve. The greater the constriction, the harder the right ventricle must pump to force blood into the pulmonary artery.

What is moderate right distal carotid artery stenosis? The carotid arteries are a pair of arteries that serve as the main pipelines bringing oxygen-rich blood to the brain. The carotid arteries travel through the neck, next to the windpipe. Stenosis means an abnormal narrowing of a body part -- in this case, an artery. Distal means the far end of a body part.

Renal Artery Stenosis Other causes of stenosis (narrowing) of the renal artery include: 1  fibromuscular dysplasia, an abnormal thickening of the muscles of the artery wall, most often seen in young women. 2  arteritis or inflammation of the artery. 3  aneurysm of the artery.  compression of the artery by an outside mass; for example, a tumor.

Renal Artery Stenosis In younger patients, the narrowing of the renal artery usually is due to the thickening of the artery (fibromuscular dysplasia) and it is more common in women than men. It is estimated that renal artery stenosis accounts for approximately 1% of mild to moderate cases of high blood pressure.he majority of renal artery stenosis is caused by atherosclerosis (hardening and narrowing of blood vessel wall from the inside) similar to the process that occurs in blood vessels in the heart and other parts of the body.

Renal Artery Stenosis A. A. Renal artery stenosis is a narrowing of arteries that carry blood to one or both of the kidneys. Most often seen in older people with atherosclerosis (hardening of the arteries), renal artery stenosis can worsen over time and often leads to hypertension (high blood pressure) and kidney damage.ore 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.

Carotid Artery Stenosis What is carotid artery stenosis? Carotid artery stenosis is a narrowing in the large arteries located on each side of the neck that carry blood to the head, face and brain. The narrowing usually results from atherosclerosis, or a build-up of plaque on the inside of the arteries. Over time, stenosis can advance to complete blockage of the artery.

- Aortic valve stenosis occurs when there is a thickening or narrowing of the aortic heart valve. This reduces blood flow from the heart to the aorta and the rest of the body. The aorta is the largest artery in the body. It leads from the left ventricle down to the lower part of the body.

Renal Artery Stenosis Renal artery stenosis is the narrowing of one or both renal arteries. “Renal” means “kidney” and “stenosis” means “narrowing.” The renal arteries are blood vessels that carry blood to the kidneys from the aorta—the main blood vessel that carries blood from the heart to arteries throughout the body. RVH is high blood pressure caused by RAS.

Aortic stenosis Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level.

Carotid stenosis  (carotid artery disease) Carotid stenosis is a progressive narrowing of the carotid arteries in a process called atherosclerosis. Normal healthy arteries are flexible and have smooth inner walls. As we age, hypertension and small injuries to the blood vessel wall can allow plaque to build up.arotid stenosis is a progressive narrowing of the carotid arteries in a process called atherosclerosis.

Intracranial artery stenosis Intracranial stenosis is a narrowing of an artery inside the brain that can lead to stroke. Stenosis is caused by a buildup of plaque inside the artery wall that reduces blood flow to the brain.The process of plaque buildup is called atherosclerosis. Atherosclerosis that is severe enough to cause symptoms carries a high risk of stroke and can lead to brain damage and death.laque can grow larger and larger, severely narrowing the artery and reducing blood flow to the brain. Plaque can eventually completely block (occlude) the artery. Plaque can roughen and deform the artery wall, causing blood clots to form and blocking blood flow to the brain.

Endocarditis Aortic valve stenosis is an abnormal narrowing of the aortic valve of the heart. The causes of aortic stenosis are wear and tear of the valve in the elderly, congenital, or scarring or scarring of the aortic valve from rheumatic fever. Symptoms include angina, fainting, and shortness of breath.
