What is Azygos vein?

Azygos vein is located along the right side of the thoracic vertebral column and carries a deoxygenated blood from the chest and abdomen areas to the heart. Unlike most veins and arteries, he does not have a match on the left side of the body, explaining his name, which means "unpaired" in Greek. The veins that perform a similar function can be found on the left side of the body, but these are considered to be tributaries, and thus only parts of the Azygos venous systems system rather than the equivalent body structures. Some of these tributaries on the left are hemiazygos veins and back intercostal veins. The blood in the veins of Azygos flows into the superior vena Cava, which then transmits it to the heart to recirculate.

Although many lives and arteries in the body have a similar structure and function in all individuals, the Aygos veins can be configured differently from man to person. Sometimes azygos system lived alive different areas of abdomites in some cases not only administer abdominal and thoracic walls, but also receive blood from bronchial and gonadallived. The azygos venous system also differs structurally in different mammal types. People, dogs and cats do not have paired veins azygos, but cows, sheep and other ruminants.

Sometimes the thoracic and uterine veins can be endangered so that they do not work as well as they should. This is referred to as chronic cerebrination venous insufficiency (CCSVA), which can lead to reduced brain function, as well as stenosis or abnormal narrowing of the vein. The overall narrowing or blocking of veins that drain the upper body causes the deoxygenated blood to connect in the brain, cause swelling and slows the supply of oxygenated blood back to the brain and relieves the brain of much needed oxygen.

Paolo Zamboni, Italian Vascular Surgeon and Scientist, described the CCSVI in 2008 and quoted research that suggests that it is very common in patients who have multiple sclerosis and that this could cause a wide range of symptoms of the United StatesH with this devastating disease. Zamboni's study included close observation and testing of the Azygos system in subjects with multiple sclerosis. Some doctors and scientists believe that further study and treatment of CCSVA and stenosis of the Azygos system could lead to new and more effective treatment for multiple sclerosis.
