What is Venous Thromboembolism (VTE)?

Venous thromboembolism (VTE) is a condition in which blood clots form in the deep veins of the legs, pelvis or arms and travel to the heart and lungs. Blood clots which form and reside within the deep veins of the upper and lower extremities and pelvis are termed Deep Venous Thromboses or DVTs. While DVTs are not, in themselves, life-threatening, the condition can become deadly if the blood clot travels to the lungs and becomes a pulmonary embolism or PE, interrupting normal blood flow to the lungs.
