Venous Thromboembolism (VTE)
This condition, commonly called "VTE," occurs when a blood clot forms in a vein deep within your body. This can happen in your leg, or in another part of your body. The clot travels through your circulatory system. When it reaches your lungs, it blocks an artery within them. This prevents oxygenation of your blood. This is a pulmonary embolism. It can be fatal.
