Deep vein thrombosis, or deep venous thrombosis, (DVT) is the formation of a blood clot (thrombus) within a deep vein, predominantly in the legs. Non-specific signs may include pain, swelling, redness, warmness, and engorged superficial veins. DVT often develops in the calf veins and "grows" in the direction of venous flow, towards the heart. When DVT does not grow; it can be cleared naturally and dissolved into the blood (fibrinolysis).
Data has shown that the risk of recurrent VTE can increase cumulatively in patients who are not treated with standard therapy from 11% after one year to up to 40% after 10 years. Data has shown that up to 30% of people who experience a venous thromboembolic event (deep vein thrombosis or pulmonary embolism) die within three months.
The basic treatments for the disease are Anticoagulation, which prevents further coagulation, home treatment, stockings, walking, and repeat imaging and IVC filters, thrombolysis, and thrombectomy. The aims of the physicians are to prevent clot becoming larger, clot becoming lose and traveling to lungs, new clot formation and Post thrombotic syndrome.
Major Research on Disease
The current major research on the diseases are efficacy of low doses of heparin for the prevention of the DVT after a major surgery, accuracy of the clinical assessment for DVT, Decreased plasma levels of activated factor VII in patients with deep vein thrombosis etc.
