Almost everyone heard about blood clots.
But most can not imagine how they are dangerous. Clot formation - a natural defense mechanism of the body, which prevents the loss of blood vascular lesions.
His education may be associated with certain pathologies, but not impaired vascular integrity.
What is a blood clot
Thrombus - a blood clot that forms inheart cavity or blood vessels. There are 2 types of clots: bridging (produced in small vessels) and parietal (can be formed in the cavities of the heart and larger vessels). A blood clot is formed at once, the process of the emergence of a fairly long. Initially, in the heart or in the walls of blood vessels are formed plaques that eventually grow and grow. Then, from the plaques formed a blood clot, which can break off and cause health irreversible negative consequences.
Typically, clots are formed due to an increase in blood viscosity, changes in vessel walls and blood circulation disorders.
Why is the blood clot can break away
At various pathologies of the circulatory system andheart more and more fat accumulates on the inner walls of blood vessels. They narrow the lumen, increased blood pressure resulting in humans. Under the influence of a strong pressure, the blood flows through the vessels at a greater rate than under normal conditions. This accelerated the flow of blood can hurt or tear off a piece of cholesterol plaque or a blood clot formed from the wall of the vessel or cavity of the heart and carry it on until it reaches the vessel, smaller in diameter than himself. Then it can develop sudden and very dangerous syndrome - thromboembolism, which kills more than 100 000 people in Russia.
Also, a blood clot can break away from the arterial wallor vein in the preparation of human bruised or blunt trauma. For example, if a blood clot is located in the leg arteries, a man shoots at the place of dislocation, he can easily break away from the vessel wall.
How to recognize the presence of a blood clot
When a blood clot strikes the brain artery,stroke occurs. The main signs are in violation of the sensitivity of the limbs and activity in human paralysis. A person may skew, broken speech and vision.
If it affects the coronary arteries occursmyocardial infarction. A characteristic feature - the pain behind the breastbone. She can wear a crushing, squeezing, or baking in nature. Also, pain can be given in both arms, neck, abdomen, or interscapular region.
If the clogged vessels intestine, mesenteric thrombosis develops, whereupon peritonitis and necrosis appear.
If thrombosing vessels of extremities, with a high probability develop gangrene. First limbs become cold and pale, and then comes death.
Thrombosis of the pulmonary artery leading to suffocation and skin blue.
