Thrombosis is the formation of a blood clot, known as a thrombus, within a blood vessel. It prevents blood from flowing normally through the circulatory system.

Veins carry blood from the body back into the heart. Blood Thinners. These drugs, also called anticoagulants, are the most common treatment for DVT. They can keep a clot from growing or breaking off, and they prevent new clots from forming. But they can't thin your blood, despite their name, or dissolve an existing clot. Anticoagulant therapy is recommended for 3-12 months depending on site of thrombosis and on the ongoing presence of risk factors. A newer treatment involves breaking up and sucking out the clot through a small tube in the vein. In broad terms, arterial thrombosis is treated with drugs that target platelets, and venous thrombosis is treated with drugs that target proteins of the coagulation in our blood.
