Stenosis, Spinal Causes, Symptoms and Treatment and Related Disorders ...
Stenosis, pulmonary: The pulmonary valve is too tight so that the flow of blood from the right ventricle of the heart into the pulmonary artery is impeded. This means the right ventricle must pump harder than normal to overcome the obstruction.
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.
Spinal stenosis in the neck
Numbness or weakness. Spinal stenosis in your upper (cervical) spine can cause numbness, weakness or tingling in a leg, foot, arm or hand. You may drop things more often or have a tendency to fall.
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.

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.
This is a condition where there is narrowing of the spinal canal.

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.
Spinal stenosis fundamentals
With age, the spinal canal - located in the lower back - can narrow, resulting in spinal stenosis. The narrowing process, which is gradual, reduces the space available for the spinal cord and nerves.

What is pyloric stenosis?
Pyloric stenosis is a problem that affects babies between 2 and 8 weeks of age and causes forceful vomiting that can lead to dehydration.
Pyloric stenosis: Treatment
Pyloric stenosis is considered to be a medical emergency. Immediate treatment requires replacement of fluid loss, electrolytes, and acid-base imbalance. Correction needs to be done and this involves surgery.
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 ...
Aortic Stenosis - Side effects
The MedicineNet physician editors ask:
What side effects did you have with your aortic stenosis?
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.
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.
Aortic stenosis (AS) is narrowing of the aortic valve obstructing blood flow from the left ventricle to the ascending aorta during systole.
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.
Aortic stenosis is a condition in which the opening of one of your heart valves (aortic valve) becomes narrowed, which keeps the aortic valve from opening fully. This reduces blood flow from your heart to the main artery of your body (aorta).
Mitral stenosis in people of all ages is treatable. Treatment depends on the severity and progression of your condition and signs and symptoms. If the condition is severe enough, you may need heart surgery to repair or replace the valve.
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.
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.
Severe stenosis in newborns causes signs and symptoms of:
cyanosis (bluish tinge to skin color)
pale, cool or clammy skin

Pyloric stenosis is a condition that develops in babies in the first few weeks after they are born. It means that part of the baby's digestive system has narrowed, so milk can't get out of the stomach to be digested.
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 ...

Aortic valve stenosis can occur because of a birth defect in the formation of the valve. Calcium deposits may form on the valve with aging, causing the valve to become stiff and narrow. Stenosis can also occur as a result of rheumatic fever.
Renal artery stenosis is the narrowing of one or both renal arteries. 'Renal' means 'kidney' and 'stenosis' means 'narrowing.
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.
Aortic valve stenosis is a narrowing of the aortic valve. The aortic valve allows blood to flow from the heart's lower left chamber (ventricle) into the aorta and to the body.
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.
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, ...

Supravalvar aortic stenosis (usually membranous) sometimes associated with pulmonary valvular or peripheral arterial stenosis but with normal facies and mentality; autosomal dominant inheritance.

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.
Symptoms of DACRYOSTENOSIS

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.
stenosis (or narrowing of the valve)
The valve(s) opening becomes narrowed or valves become damaged or scarred (stiff), inhibiting the flow of blood out of the ventricles or atria.
the abnormal narrowing of a normal opening in the esophagus, intestines, or anus.

Restenosis of a Stent-Widened Coronary Artery
The illustration shows the restenosis of a stent-widened coronary artery. In

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.
Some people are born with narrowed canals. Most often stenosis is a result of aging. Conditions that can cause spinal stenosis include: ...
