Venal thrombosis deep

The deep venal thrombosis, also known as deep vein thrombosis is a condition that occurs when a blood clot, also called a thrombus grows inside a deep venous blood vessel. The thrombus obstructs the passage of all or part of blood, preventing its normal circulation and creating a serious problem for the entire body's blood circulation.
The deep venal thrombosis is a serious condition and relatively common. Generally the thrombus responsible for the obstruction of blood formed on the calf, but may also occur on the thighs and occasionally on the upper limbs. His detachment can cause complications in the short and long term. In the short term, the detachment of the thrombus can travel to the lung, blocking an artery and causing what is called pulmonary embolism, which can lead to death. In the long term, the detachment of thrombus can cause chronic venous insufficiency syndrome or post-flebítica, caused by destruction of the veins, responsible for carrying deoxygenated blood back to the heart.
The development of deep venal thrombosis may be related to three factors:
- Decrease in the rate of blood flow, as in people who are bedridden for long periods of time, people who are seated for long in the same position (in front of the computer, long trips);
- Occurrence of rupture in the vessel inner wall that favor the formation of thrombi, as in trauma, infections and intravenous medications;
- Increased susceptibility to blood clots, such as during pregnancy, contraceptive use, and in people who have diabetes and blood diseases.
Although, in most cases, is asymptomatic, some people may experience symptoms such as swelling, pain, heat, redness, stiffness of the muscles in the area where the thrombus, darker color of the skin, subcutaneous tissue hardening, eczema and ulcers.
Treatment
The treatment of venal thrombosis deep is made from anticoagulant (such as heparin and awarfarina) and fibrinolytics that help dissolve the thrombi. There are cases where surgery is necessary.
Prevention
The best way to prevent thrombosis is deep venal use anticoagulant medications at low doses (for patients who are long rest); doing physical activity, not smoking, and maintaining proper weight.
