thrombosis is caused by a blood clot clogs an artery or vein. When the clot travels through vessels and obstructs one that is smaller than its size, we have a stroke.
Thrombosis and embolism:¿What are?
The thrombosis is a blood clotting within an artery or vein due to an alteration of the glass, as an inflammatory process, stenosis or stricture. In turn, this causes a decrease in blood velocity and an alteration of blood clotting.
The most common reasons for a arterial thrombosis are diabetes, high blood pressure, cholesterol and triglycerides too high or smoking or other drug addiction. A venous level, thrombosis may be due to an inflammatory process of the vein, a decrease of blood velocity as varicose veins or an alteration of blood clotting.
The embolism, however, is a blood clot that occurs in a particular area of our body and travels through the arteries and veins to seal a vessel is less the same caliber clot. Both thrombosis and embolism cause the blocked area lacks the necessary blood flow.
¿As thrombosis and embolism manifest?
A thrombosis or arterial embolism provoke, if a Tip, intense pain from lack of blood supply, pallor with decrease in external temperature and a loss of strength and mobility in the arm or leg. If in an artery of heart, may cause a heart attack, which can even be complicated and lead to cardiac arrest.
If the lack of irrigation occurs in the brain, we will be in front of a stroke or stroke. Depend on the extent and location, this will be more or less severe, but a stroke can result in bleeding or“& rdquo ;, spill that complicate the injury.
On the other hand, there emboli reaching clog an artery in the lung ( what is known as pulmonary embolism ). This causes an acute respiratory failure and, in some cases, causing death by cardiorespiratory collapse. 99 % of pulmonary embolisms are caused by thrombosis in the legs.
¿That is a trombofeblitis?
Commonly called“ feblitis&rdquo ;, is a varicose vein thrombosis or superficial vein. It appears as a hard cord, embossed skin, red, and painful because of the coagulation of the blood inside this glass. It is a common complication of varicose veins, but the risk is that the trombofeblitis occur in a saphenous vein, as these communicate with the deep venous system and this could cause a pulmonary embolism.
In these cases proceed to descoagular the patient and disconnect the vein surgically trombofeblitis. It is inadvisable sclerose a saphenous vein to treat venous insufficiency, as there is likely to cause a pulmonary embolism by thrombosis reduced by the foam sclerosis. Therefore, although varis sclerosis is useful in medium and small caliber saphenous veins always treated surgically.
