Aortic Stenosis Aortic stenosis (AS) is a narrowing of the aortic valve in the heart. This valve is located between the left ventricle (lower pumping chamber) and the aorta. The aorta is the largest artery in the body. It transports blood from the heart throughout the body. The aortic valve has three cusps, or flaps, that control the direction and flow of the blood. Aortic stenosis causes obstruction or blockage of blood flow through this valve.

Carotid Artery Disease Carotid artery disease is caused by atherosclerosis (hardening of the arteries). Atherosclerosis means fatty deposits build up in an artery and form plaque. Plaque buildup is what narrows or blocks one or both carotid arteries. Plaque in the arteries also increases your risk for blood clots.

Carotid Artery Disease: Causes, Symptoms, Tests, and Treatment Carotid Artery Disease: Causes, Symptoms, Tests, and Treatment. Carotid artery disease is also called carotid artery stenosis. The term refers to the narrowing of the carotid arteries. This narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery.

Carotid Artery Disease: Causes, Symptoms, Tests, and Treatment Carotid Arteries Disease: Also called carotid artery stenosis, the term refers to the narrowing of the carotid arteries. This narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery. When the carotid arteries are obstructed, you are at an increased risk for a stroke, the third leading cause of death in the U.S.

Intracranial artery stenosis Intracranial stenosis is a narrowing of the arteries inside the brain. Similar to carotid stenosis in the neck, it is caused by a buildup of plaque in the inner wall of the blood vessels.

Aortic stenosis Aortic stenosis is most commonly caused by age-related progressive calcification (>50% of cases) with a mean age of 65 to 70 years. Another major cause of aortic stenosis is the calcification of a congenital bicuspid aortic valve (30-40% of cases) typically presenting earlier, in those aged 40+ to 50+.

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.

Blogs Photos Forums What's eating the rose foliage? Posted by Miranda Hodgson on 13 Aug 2012 at 12:35 PM. Something is eating the leaves on the roses – if left to it, stem-like leaf veins would be all that remain. Seeing the ragged foliage and looking more closely, I see around the leaf edges tiny creatures that resemble caterpillars. They are not caterpillars, though, they are rose sawfly larvae. There are two common species of rose sawfly in the UK, Arge pagana and Arge ochropus, with A. pagana being the most common.

- 1 A blockage in the renal arteries (arteries supplying the kidneys) can cause renal artery disease (stenosis). 2  The symptoms include uncontrolled hypertension (high blood pressure), heart failure, and abnormal kidney function.eripheral Artery Disease. Like the blood vessels of the heart (coronary arteries), your peripheral arteries (blood vessels outside your heart) also may develop atherosclerosis, the build-up of fat and cholesterol deposits, called plaque, on the inside walls. Over time, the build-up narrows the artery.

Renal Artery Stenosis Renal artery stenosis (RAS) is a blockage of an artery to the kidneys. It may cause kidney failure and hypertension (high blood pressure). Smokers have a greater risk of developing RAS. RAS is most common in men between the ages of 50 and 70.hese complications affect the blood circulation of the kidneys, and may cause damage to the tissues of the kidneys, kidney failure, and/or high blood pressure. Vascular conditions affecting the renal arteries and veins include the following: Renal artery stenosis.

Artery Stenosis This can occur if the artery blocks off suddenly, or more gradually if there is a serious narrowing. In its early stages, kidney failure does not cause symptoms, but is only detected in blood tests. The prevention of kidney failure is one of the main aims when doctors treat renal artery stenosis. High blood pressure  One of the jobs the kidneys normally perform is to control the blood pressure. If they are starved of blood, this can cause high blood pressure.

Celiac Artery Stenosis E-chocardiography Journal: Alphabetical List / Chronological List / Images / Home Page. Celiac artery stenosis may be caused by atherosclerotic degeneration or by compression exerted by the arched ligament of the diaphragm. Celiac artery compression syndrome (angina abdominis) is abdominal or epigastric pain triggered by meals. Symptoms may resolve after surgical resection of the arched ligament.

Narrowing Artery â Causes of Arterial Stenosis A narrowing may be due to pathology within the artery, in the artery wall or from outside of the artery. Atherosclerosis is the most common cause of arterial narrowing. The formation of atheromatous plaques within the wall of the artery bulges into the lumen and partially reduces blood flow to target organs. Atherosclerosis is progressive – it develops slowly over time.

Renal Artery Stenosis Renal artery stenosis usually does not cause any specific symptoms. Sometimes, the first sign of renal artery stenosis is high blood pressure that is extremely hard to control, along with worsening of previously well-controlled high blood pressure, or elevated blood pressure that affects other organs in the body.

What Is Spinal Stenosis? The leading reason for spinal stenosis is arthritis, a condition caused by the breakdown of cartilage -- the cushiony material between your bones -- and the growth of bone tissue. Osteoarthritis can lead to disc changes, a thickening of the ligaments of the spine, and bone spurs. This can put pressure on your spinal cord and spinal nerves.

Symptoms of Carotid Stenosis Carotid artery stenosis or carotid artery disease pertains to a narrowing activity within the heart’s carotid arteries, usually as a result of atherosclerosis or the build-up of plaque. As the build-up of fatty materials increases, it eventually forms a plaque under the carotid arterial wall’s inner lining.
