What is a blood clot
A thrombus is a blood clot that forms in a cavity of the heart or blood vessels. There are 2 kinds of blood clots: plugging (formed in the small blood vessels), and parietal (can be formed in the cavities of the heart and larger vessels). A clot is formed immediately, the process of the emergence is quite long. Originally in the heart or on the walls of blood vessels are formed plaques that grow over time and increase. Then the plaque is formed thrombus, which could come off and cause irreversible negative health consequences.
Typically, blood clots are formed due to the increase in blood viscosity, changes in the walls of blood vessels and blood circulation disorders.
Why the blood clot can break away
In various pathologies of the circulatory system and the heart on the inner walls of blood vessels accumulate more and more deposits. They narrow the vessel lumen, resulting in humans, increased blood pressure. Under the influence of high pressure blood passes through the vessels with greater speed than under normal conditions. This accelerated flow of blood can hurt or tear a piece of cholesterol plaque or a blood clot formed from a wall of a vessel or cavity of the heart and carry it further, until he reaches a vessel smaller in diameter than itself. Then you can develop a very dangerous and sudden syndrome - thromboembolism, which in Russia die each year over 100,000 people.
Also the blood clot can break loose from the wall of the artery or vein when a person is hurt or blunt injuries. For example, if the clot is in the arteries of the legs, and the man swiped at his place of deployment, it can easily break away from the vessel wall.
How to recognize the presence of a blood clot
When the clot affects the arteries of the brain, stroke occurs. The main signs are in violation of the sensitivity and activity of the limbs, in humans paralysis. A person can skew, impaired speech and vision.
When coronary arteries occurs myocardial infarction. Characteristic symptom is pain behind the breastbone. It can be oppressive, baking or compressive in nature. Also the pain may radiate to both arms, neck, stomach or interscapular region.
If clogged blood vessels of the intestine, develops mesenteric thrombosis, then there are peritonitis and necrosis.
If trombicula the vessels of the extremities, with a high probability of developing gangrene. First, the extremities become cold and pale, and then necrosis occurs.
Thrombosis of the pulmonary artery leads to suffocation and bluish discoloration of the skin.
