1. Stricture of the lacrimal duct.
The pathway in the human body in which the spinal cord and nerves run through is called the spinal canal. When the spinal canal narrows it will increase the pressure that is put on the nerves. This condition is called spinal stenosis.
The aorta is the main artery carrying blood out of the heart. When blood leaves the heart, it flows through the aortic valve, into the aorta. In aortic stenosis, the aortic valve does not open fully. This decreases blood flow from the heart.

The most common cause of aortic stenosis is age-associated degeneration and calcification of the aortic valve, which often causes symptoms in elderly patients.
Aortic stenosis is the abnormal narrowing of the aortic valve. Symptoms include breathlessness, fainting, coughing at night and pains in the chest (from angina). Treatment includes medications and surgery.
In boys the meatus is the opening through which urine passes. Sometimes, particularly in circumcised boys, irritation of the tip of the penis causes scar tissue to form around the meatus, making it smaller.
Sometimes the opening of the penis where urine passes can become blocked and can cause various problems with urination. The following information should help you understand this condition and how it can be treated.

Pyloric stenosis can contribute to:
malnutrition: food does not move into the small intestine where it would normally be digested and used by the body
dehydration: a baby with this condition is at an increased risk for dehydration due to frequent vomiting ...
When stenosis occurs in the lower back, it is called lumbar spinal stenosis. It often results from the normal aging process. As people age, the soft tissues and bones in the spine may harden or become overgrown.
Dacryostenosis, or stenosis of the tear duct, is a congenital blockage of the tear duct, occurring in approximately 5% of babies. In these infants, the opening of the tear duct, a passage that drains tears from the eyes into the nose, fails to open before birth.
Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart. Stenosis refers to a condition in which the valve does not open fully, restricting blood flow.
Spinal stenosis, a condition that causes narrowing around the spinal cord and nerves.
In spinal stenosis, one or more areas in the spine narrow - especially in the upper or lower back - putting pressure on the spinal cord or on the roots of these branching nerves.
Aortic stenosis (AS) is narrowing of the aortic valve obstructing blood flow from the left ventricle to the ascending aorta during systole. Causes include a congenital bicuspid valve, idiopathic degenerative sclerosis with calcification, and rheumatic fever.
Aortic stenosis may be present from birth (congenital), or it may develop later in life (acquired). Children with aortic stenosis may have other congenital conditions.
Spinal stenosis is a condition in which the spinal canal narrows and pinches the nerves, resulting in back and leg pain.
Aortic stenosis refers to a condition that causes obstruction to blood flow between the left ventricle and the aorta. There are a variety of causes, including muscular obstruction below the aortic valve, obstruction at the valve itself, or aortic narrowing immediately above the valve.
Aortic stenosis means that when the aortic valve opens, it does not open fully. It is narrowed (stenosed) when it is open. Therefore, there is a partial restriction of blood flow from the left ventricle into the aorta.
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. Spinal stenosis occurs most often in the neck and lower back.
Mitral stenosis restricts the flow of blood into your left ventricle and your aortic stenosis restricts the flow of blood out of your ventricle, causing the ventricle itself to become small and stiff, with thickened walls.
Tracheal stenosis occurs because of damage to endotracheal tissue that causes cicatricial stenosis.

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 ...
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.
Aortic valve stenosis means that this valve has narrowed, and it can't open all the way. The heart has to work harder to pump blood through the smaller opening. The heart can do this for many years, but over time it gets worn out. It can no longer send out as much blood as your body needs.
Mitral Valve Stenosis
The heart is a beating muscle that pumps blood throughout the body. Inside the heart, four valves direct blood flow in the appropriate path. However, a valve that has become narrowed or thickened can compromise blood flow.

Compare: Williams syndrome.
Lumbar spinal canal stenosis is not the same as a ruptured disk. A ruptured or "herniated" disk usually pinches 1 or 2 nerves at a time. The pain caused by a ruptured disk in the lumbar spine is usually easy to diagnose and is known as sciatica.
Stenosis is cardiac disorder in which one or multiple valves of the heart are narrow. This narrowing will then cause the respective valve(s) to open incorrectly, restricting blood flow not only though the heart, but to the rest of your body.
The narrowing or constriction of a blood vessel or valve in the heart.
A disease of the heart muscle that causes it to lose its pumping strength.
Stenosis - The opening of the valve is too narrow, and this interferes with the forward flow of blood
Regurgitation - The valve doesn't close properly. It leaks, sometimes causing a significant backflow of blood.
stenosis (narrowing) - if the aortic valve becomes narrowed and obstructs the blood flowing through it, or
regurgitation (leaking) - if the aortic valve leaks and blood flows back through the it into the left ventricle. This is also known as incompetence or a leaking valve.
Stenosis: 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.
Syncope: A brief loss of consciousness caused by temporary lack of oxygenated blood.
Stenosis (or narrowing of the valve). The valve(s) opening becomes narrowed, limiting the flow of blood out of the ventricles or atria. The heart is forced to pump blood with increased force in order to move blood through the narrowed or stiff (stenotic) valve(s).
Stenosis: Valve stenosis is when a heart valve does not open fully to allow adequate flow of blood.
Stent: A short tube of metal mesh inserted at the part of the artery which is to be widened by coronary angioplasty.
stenosis, pl. stenoses (sten-O-sis, sten-O-sEs)
An abnormal narrowing of any canal; for example, a narrowing of one of the cardiac valves.
Narrowing of an opening or passageway in the body. Stenosis of an artery may reduce blood flow through the vessel.

The recurrence of a blood vessel blockage after it was intervened upon (usually seen in vessels after stenting, atherectomy, or balloon angioplasty procedures).
Spinal stenosis is a narrowing of the spinal canal. The spinal canal is located within the backbone. It is a small space that holds the nerve roots and spinal cord. If this space becomes smaller, it can squeeze the nerves and the spinal cord.
Spinal stenosis - a condition that causes a narrowing of the canal that holds the spinal cord and many nerve roots. This may cause pressure on the sciatic nerve.
