Varicose veins of the esophagus

varicose veins of the esophagus, or flebektaziya - a pathological change in the veins of the esophagus, which is a consequence of impaired blood flow in the vena cava and manifested uneven increase in the vascular lumen in the form of protrusions meshochkoobraznyh their walls.At postmortem examination veins of the esophagus and gastric cardia often extended, twisted, mucous membrane over them thinned, sometimes inflamed or eroded.The hole from which the bleeding is usually not noticeable, t. To. After heavy bleeding veins subside.

reasons for the vast majority of cases, varicose veins of the esophagus are the state, accompanied by the phenomenon of increasing the pressure in the vena cava - portal hypertension:

Flebektaziya may be a sign of severe chronic heart failure - in this case it is due to hypertension, not only inportal vein, and in

the systemic circulation as a whole.

There is a congenital form of the disease - its causes are unknown.

pressure in the portal vein of a healthy person varies between 5-14 cm of water.Art., esophageal varices develop when sustained pressure increase 2-4 times higher than normal.24-27 cm of water pressure.Art.It considered critical - with these figures there is a real threat of rupture of the esophagus.

When the pressure in the portal vein dramatically impeded outflow of blood from the veins in the esophagus, they are experiencing increased stress, resulting in deformed - elongate, widen, becoming ornate shape their walls form meshochkoobraznye protrusions, or varicose veins.
At initial pathology of the liver affected veins are located in the lower, or distal, end of the esophagus, in the case of initial cardiovascular disease - all over the body.As for the size of the nodes, then for heart failure are 2-3 times smaller in diameter than the liver disease.

complication of varicose veins is bleeding are arising in the case of sudden changes in pressure in the portal vein.The pressure in this case is not fundamental, it plays the role of pressure fluctuation range of numbers.Usually, bleeding occurs during physical exertion, after eating, during sleep.It is important to understand that the incidence of bleeding and the degree of severity are not associated with the caliber (diameter) of the affected veins, and depend on the state of the vascular wall (degree of permeability), blood clotting and other factors.Often bleeding from esophageal varices are fatal.

In men, this pathology is diagnosed in 2 times more often than women, the average age of onset of the disease - 50 years.
In most cases, esophageal varices for a long time, asymptomatic or the symptoms are masked by symptoms of the underlying disease.Patients who have been diagnosed with esophageal varices, for some time noted:

above symptoms are usually caused by inflammation of the esophageal mucosa, or peptic esophagitis, often accompanied by varicose veins.

Often the disease is asymptomatic until until it develops bleeding from the affected veins.It can be as small or massive, profuse, a danger to the patient's life.

Acute bleeding manifested by the presence of streaks of blood in the sputum, vomit red blood, vomiting "coffee grounds", a black loose stools (it is called "melena").In the case of chronic blood loss develops iron deficiency anemia, which are signs of weakness, palpitations, shortness of breath, weakness, "wanton" weight loss.

The diagnosis of varicose veins play a role:

patient should understand that if the result of his illness was the main esophageal varices, the cure of the disease the chances of him, alas, no.The aim of treatment in this case is to prevent life-threatening condition - bleeding from the affected veins.

offer you the basic principles of treatment of varicose veins of the esophagus.

Unfortunately, esophageal varices incurable.However, in the case of timely diagnosis of an adequate maintenance treatment significantly improve the quality of life and help prevent the terrible condition - the bleeding.

Mortality has arisen bleeding from esophageal varices is more than 50%, depending on the severity of the underlying disease and the condition of the body as a whole.In more than half of the patients who survived after bleeding for 1-2 years diagnosed with a relapse.Long-term survival after hemorrhage is almost impossible because of the severity of the underlying disease.
