Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein, usually in the legs.

Clots can form in the superficial veins and deep veins. Blood clots with inflammation of the superficial veins (called superficial thrombophlebitis or phlebitis) rarely cause serious problems. But clots in the deep veins (deep vein thrombosis) require immediate medical attention.

These clots are dangerous because they can come off, cross the bloodstream to the lungs and block blood flow to the lungs (pulmonary embolism). Pulmonary embolism often puts life in danger. PST can also cause long-term problems. DVT can damage the vein and cause the leg to give, inhale and change color.

Blood clots usually form in the veins of the calf and thigh, and less frequently in the veins of the pelvic arm or veins. This topic focuses on blood clots in the deep veins of the legs, but the diagnosis and treatment of DVT in other parts of the body are similar.
What are the causes of deep venous clot formation?

Blood clots can form in the veins when you are inactive. For example, clots may form if you are bedridden or bedridden, or if you have to sit for a long flight or a car trip. Surgery or injury can damage blood vessels and cause clot formation. Cancer can also cause DVT. Some people have blood that coagulates very easily, a problem that can occur in families.
What are the symptoms?

Symptoms of DVT include swelling of the affected leg. In addition, the leg can become hot and look more red than the other leg. Your calf or thigh can hurt you or be gentle when you touch, squeeze, or stand up or move. The pain may worsen and last longer or become constant.

If a blood clot is small, it can not cause symptoms. In some cases, pulmonary embolism is the first sign of DVT.
How to diagnose deep vein thrombosis?

If your doctor suspects that you have DVT, you will probably need to have an ultrasound to measure blood flow in your veins and help detect blood clots that may block it.
How is it treated?

Treatment reduces the likelihood that the blood clot will develop or a piece of clot will come off and flow into the lungs.

Treatment of DVT generally involves the ingestion of anticoagulants, such as heparin and warfarin (eg Coumadin). Heparin is administered intravenously or intravenously or by injection. Warfarin is given as a tablet. Treatment usually involves ingestion of anticoagulants for at least 3 months to prevent the growth of existing clots.

Your doctor may also recommend that you hold or raise your leg where possible, walk and wear compression stockings. These measures can help reduce the pain and swelling that can occur with DVT.
How to prevent deep vein thrombosis?

You can do some things to avoid DVT. After surgery, you can take an anticoagulant to prevent blood clots. You can also use compression stockings. You can try to get up and get up as soon as possible after an illness or an operation. If you sit for a long time, for example during a long flight, you can exercise your legs to promote blood circulation.
