Stenosis A stenosis (/stəˈnoʊsɨs/ ; plural: stenoses, /stəˈnoʊˌsiːz/) (from Ancient Greek στένωσις, narrowing) 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).tricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g., achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g., atherosclerosis).

What Is Carotid Stenosis? Carotid stenosis is a narrowing or blockage of the carotid arteries. Located in the side of the neck, the left and right carotids are two large arteries that carry oxygen-rich blood to your brain.You can feel your carotids pulsate when you place your index finger right below the angle of your jaw.arotid stenosis is a narrowing or blockage of the carotid arteries. Located in the side of the neck, the left and right carotids are two large arteries that carry oxygen-rich blood to your brain.

Coronary ostial stenosis Overview. Coronary ostial stenosis refers to the narrowing of the ostium part of the coronary arteries. An ostial lesion is defined as a lesion which begins within 3-5 mm of the origin of a major epicardial artery. key issue in the treatment of an ostial lesion is to assure that the stent is inserted proximal enough to fully cover the aorto-ostial junction (particularly in the right coronary artery). Essentially the operator must realize that the aortic wall is being stented as well.

Lumbar Spinal Stenosis The tunnel is called the spinal canal. Lumbar spinal stenosis is a narrowing of the spinal canal in the lower part of your back. Stenosis which means narrowing, can cause pressure on your spinal cord or the nerves that go from your spinal cord to your muscles. Spinal stenosis can happen in any part of your spine but is most common in the lower back.

Aortic Valve Disease Aortic valve stenosis is usually defined by restricted systolic opening of the valve leaflets, with a mean transvalvular pressure gradient of at least 10 mm Hg. The cause of the stenosis can be further defined based on the anatomy and disease process affecting the valve.alcific aortic stenosis, formerly referred to as degenerative, affects trileaflet aortic valves, often in patients with other risk factors for atherosclerotic disease. The aortic valve leaflets undergo an active disease process, with lipid deposition, inflammation, and osteo-calcific changes.

Overview Pyloric stenosis is an uncommon condition in infants that blocks food from entering the small intestine. Normally, a muscular valve (pylorus) between the stomach and small intestine holds food in the stomach until it is ready for the next stage in the digestive process.

Spinal Stenosis: Lumbar and Cervical Spinal Stenosis: Lumbar and Cervical. Spinal stenosis is a narrowing of the spinal canal, which places pressure on the spinal cord. If the stenosis is located on the lower part of the spinal cord it is called lumbar spinal stenosis. Stenosis in the upper part of the spinal cord is called cervical spinal stenosis. While spinal stenosis can be found in any part of the spine, the lumbar and cervical areas are the most commonly affected.

Medications for Aortic Stenosis Medications for Aortic Stenosis. What is Aortic Stenosis: The aorta is the large artery that originates in the left ventricle (lower chamber) of the heart. Aortic stenosis is the narrowing or obstruction of the heart´s aortic valve, which prevents it from opening properly and blocks the flow of blood from the left ventricle to the aorta.

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.

Spinal Diseases Spinal stenosis is an abnormal narrowing (stenosis) of the spinal canal that may occur in any of the regions of the spine. This narrowing causes a restriction to the spinal canal, resulting in a neurological deficit.Symptoms include pain, numbness, paraesthesia, and loss of motor control.ith spinal stenosis, the spinal canal is narrowed at the vertebral canal, which is a foramen between the vertebrae where the spinal cord (in the cervical or thoracic spine) or nerve roots (in the lumbar spine) pass through.

Spinal stenosis Learn more about this top honor. Spinal stenosis is a narrowing of the open spaces within your spine, which can put pressure on your spinal cord and the nerves that travel through the spine to your arms and legs. Spinal stenosis occurs most often in the lower back and the neck.

Understanding Cervical Stenosis Stenosis refers to narrowing of a structure in this case the spinal canal, or the bony tube in which the spinal cord and the nerve roots travel. The cervical spine is the upper portion of the spine, consisting of 7 vertebral bodies that make up what we know as the neck.

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.

Aortic Valve Stenosis Symptoms, Treatment, Types & Surgery Aortic stenosis is abnormal narrowing of the aortic valve. A number of conditions cause disease resulting in narrowing of the aortic valve. When the degree of narrowing becomes significant enough to impede the flow of blood from the left ventricle to the arteries, heart problems develop. The oxygenated blood then returns to the left atrium and passes through the mitral valve into the left ventricle. 2  Blood is pumped by the left ventricle across the aortic valve into the aorta and the arteries of the body.

spinal stenosis Spinal stenosis is a progressive narrowing of the opening in the spinal canal. The spine is a long series of bones called vertebrae. Between each pair of vertebra is a fibrous intervertebral disk. Collectively, the vertebrae and disks are called the backbone.

Rectal and Large Intestinal Atresia / Stenosis (also called anal atresia) Condition Description. Rectal and large intestinal atresia or stenosis is the term used to describe a group of rare congenital conditions of the lower gastro-intestinal tract (bowel). It can range from absence of these structures to malformations of the anus and rectum (called colon, rectum or anal atresia). If these lower gastrointestinal structures are present but only partially open to the passage of stool the condition is called colon/rectum/anal stenosis.

Aortic valve stenosis Aortic valve stenosis — or aortic stenosis — occurs when the heart's aortic valve narrows. This narrowing prevents the valve from opening fully, which obstructs blood flow from your heart into your aorta and onward to the rest of your body.When the aortic valve is obstructed, your heart needs to work harder to pump blood to your body.his narrowing prevents the valve from opening fully, which obstructs blood flow from your heart into your aorta and onward to the rest of your body.

Laryngotracheal stenosis Laryngotracheal stenosis (Laryngo-: Glottic Stenosis; Subglottic Stenosis; Tracheal: narrowings at different levels of the windpipe) is a more accurate description for this condition when compared, for example to subglottic stenosis which technically only refers to narrowing just below vocal folds or tracheal stenosis.
