Venous Thromboembolism (VTE)
Venous thromboembolism (VTE) includes both deep vein thrombosis (DVT) and pulmonary embolism (PE). DVT, usually a clot in one of the deep veins of the thighs, is not usually life-threatening; occasionally a piece of the clot breaks off and migrates toward the lung, causing PE. PE can be fatal if not treated promptly. VTE results from a combination of hereditary and acquired risk factors, including family history of blood clots, fractures of the hip or femur, heart attack or heart surgery, long-term bed rest, surgery, and use of birth control pills or estrogen therapy.
