see stricture (also stenotic).
a general term used to describe a condition in which the spinal canal narrows and presses on the nerve.
Obstruction. Valve stenosis is when a heart valve does not open fully and obstructs the flow of blood.
A condition in which a canal or other passageway in the body is constricted.
an incomplete obstruction with a small opening secondary to a diaphragm or web, whereas an atresia is a complete obstruction
tightness and compression of the spinal cord, nerve roots, or dural sac.
Blockage or obstruction...a termed used to descibe an area or zone of narrowing in any channel, including the small coronary vessels.
A narrowing, as in: aortic stenosis (narrowing of the aortic valve of the heart), pulmonary stenosis (narrowing of the pulmonary valve of the heart), pyloric stenosis (narrowing of the outlet of the stomach), and spinal stenosis (narrowing of the vertebral canal). See the entire definition of Stenosis
Reduction in the size of a vessel or other opening.

A narrowing, Examples include aortic stenosis (narrowing of the aortic valve in the heart); pulmonary stenosis (narrowing of the pulmonary valve in the heart) and pyloric stenosis (narrowing of the outlet of the stomach).
A narrowing of a passage in the body.
A narrowing or constriction of the diameter of a bodily passage or orifice.
Narrowing of a valve or an artery is called stenosis. A stenotic valve does not open completely and therefore it obstructs or blocks blood from moving through it normally. An artery can become stenotic as well, such that there is obstruction of blood flow through it to the organs of the body.
Describes a stiff heart valve or narrowing of an artery.
(Esophageal, GI tract): Narrowing.
Narrowing of the inside of a blood vessel.
A stiffening of the heart valves, which narrows its opening and can interfere with function.
the narrowing or constriction of a blood vessel or valve in the heart.
An unnatural narrowing in any passage or orifice of the body.
A constriction or narrowing of a duct or a passage.
A constriction or narrowing of a blood vessel.
Narrowing or constriction of an opening or lumen, such as blood vessel.
narrowing or tightening of an opening or passage in the body.
Narrowing; pathological compression within the spinal canal. This abnormal narrowing impedes the flow of contrast medium during imaging and has been defined as narrowing of the spinal canal, including the lateral recesses, and the intervertebral foramina due to encroachment on the neural and vascular structures by the surrounding bone and soft tissues. It can stem from a congenital defect or be acquired from tumors, osteophytes, discs, hypertrophy of the facets and ligaments, hematomas, fractures, or other causes.
Obstruction...a narrowing of the flow channel or orifice such that obstruction to blood flow occurs
Narrowing of a body passage or opening.
A narrowing of spaces in the spine (backbone) that results in pressure on the spinal cord and/or nerve roots. Spinal stenosis most often results from a gradual, degenerative aging process. As people age, the ligaments of the spine may thicken and calcify (harden from deposits of calcium salts). Bones and joints may also enlarge, and osteophytes (bone spurs) may form. This decreases the space (neural foramen) available for nerve roots leaving the spinal cord. [See: Fluoride & Stenosis
A narrowing of an area (e.g., a segment of intestine).
condition when a heart valve stiffens and doesn't open all the way, causing the heart to push blood through a smaller opening. The heart may have to work harder to move the same amount of blood. This extra work may cause the heart muscle to tire and weaken.
a general term that means "narrowing", in this course it is used to describe arterial narrowing
a narrowing of a heart valve or blood vessel.
Narrowing or stricture of a normal opening (i.e. cervical stenosis).
pathological constriction of a passageway (such as a pyloric stenosis)
Constriction or narrowing of a passage or orifice.
Stenosis or narrowing can happen in heart disease to a valve when the valve is stiff and can't open all the way. The result is that the heart must work harder to move blood. (Read about Stenosis in " The Heart and Its Valves")
narrowing of artery or heart valves.
An abnormal narrowing of a lumen, such as in a coronary artery.
Narrowing or constriction of an opening, such as a heart valve.
Pathological compression of the structures within the canal - spinal central canal, lateral recess or intervertebral foramina.
Narrowing of the openings of the foramen and/or the spinal canal; narrowing of a blood vessel.
A narrowing of a body cavity or in a tube. Many people with a tracheal stenosis re- quire a tracheostomy.
narrowing of the spinal canal; this may occur in the central lateral recess or foraminal area of the spinal canal
condition that develops when any of the four major valves that regulate blood flow through the heart and lungs thickens, becomes damaged, or is diseased
Abnormal narrowing or contraction of a channel or opening.
narrowing of any blood vessel, valve or passage
A narrowing or constriction of a passage such as a duct or a vessel.
Usually refers to narrowing of a blood vessel or cardiac orifice.
Constriction of a passage. Used typically when there is a narrowing of a valve opening (for example, mitral valve stenosis) or of a blood vessel.
An obstruction or narrowing of an opening or valve.
A narrowing of any canal. Used to describe narrowed coronary arteries or a narrowed heart valve.
the narrowing or constriction of an opening
A narrowing of a valve opening or a lumen (opening) of a vessel or graft.
Blockage or narrowing of a tube (usually a blood vessel, ureter or urethra).
the narrowing of an artery, often caused by plaque buildup.
Narrowing of a duct or canal..
narrowing of the venous channels
Narrowing of an artery due to the buildup of plaque on the inside wall of the artery.
This term means narrowing. This may occur particularly in the cervical or lumbar spine producing cervical stenosis or lumbar stenosis. If the narrowing is significant, then there is pressure on the spinal cord itself.
Any unnatural narrowing of a blood vessel, valve, digestive tract or other opening/channel in the body
closure or narrowing of any canal or vessel.
A narrowing of the heart valve orifice (opening), which prevents the valve from opening completely and decreases the blood flow through the valve. This means that the valve indicated has become so narrowed that it does not function normally.
Narrowing of a blood vessel, heart valve, or other bodily passage.
Latin for a narrowing. A narrowing of the spine would be called a spinal stenosis.
A narrowing of the canal for the spinal cord. The inner area of the spinal Encroachment of canal is smaller than normal. This can be caused by bony enlargement the spinal canal due to degenerative disc disease. 100 mm2 = relative spinal stenosis 75 mm2 = absolute spinal stenosis
a narrowing, usually refers to a valve or blood vessel.
the narrowing or constricting of a blood vessel or heart valve.
a stricture or narrowing of an artery or vein
unnatural narrowing in any passage or orifice in the body.
a narrowing of the blood vessel, which may be caused by atherosclerosis and composed of cholesterol, calcium, blood clot, plaque or scar tissue
a narrowing or contraction of an opening. aortic stenosis – obstruction of the blood flowing from the left ventricle to the aorta. mitral stenosis – narrowing of the mitral valve that separates the left atrium and the left ventricle. pulmonary artery stenosis – narrowing of the outflow from the lungs. subaortic stenosis – narrowing of the aorta just below the semilunar valves. Severity increases with age. http://www.escape.ca/~rcamken/page8.html#SUB-AORTIC STENOSIS

The closure or narrowing of an opening in the body.
Narrowing or stiffening of an opening (usually a blood vessel or heart valve).
A condition in which the spinal openings, or bony canals, become blocked or narrowed, causing nerve impingement.
A narrowing of stiffening. Mitral valve stenosis refers to scarring or calcification, which prevents the valve from opening fully and permitting blood to pass through itefficientlyy. Coronary stenosis refers to atherosclerosis or narrowing caused by a clot, either of which can prevent or slow blood flow.
Narrowing or constriction of an opening such as an artery or valve.
The abnormal narrowing of a bodily passage or opening, such as a blood vessel.
narrowing of the canal that houses the spinal cord and nerve roots.
Narrowing or blockage of an artery, leading to a decreased blood flow. Stenosis is usually caused by atheroma, fatty plaques and scar tissue that build-up on artery walls.
