(HealthDay News) -- Deep vein thrombosis (DVT), is a condition in which a blood clot forms in a deep vein, usually in the lower leg or the thigh.
The clot blocks blood flow, typically causing swelling and soreness, the American Academy of Orthopaedic Surgeons says. Blood clots may also move into the lungs and cause an often fatal condition called pulmonary embolism.
DVT is most often triggered by surgery, although poor circulation, damaged veins, tissue debris in the blood, estrogen use, pregnancy, smoking, obesity and genetics also may contribute to DVT.
Common treatments include physical therapy, exercise and elastic stockings that compress the veins. Anticoagulants, which are anti-clotting medications, often are prescribed to prevent a recurrence.
