Deep Vein Thrombosis (DVT) is a condition where blood clots form in the deep veins of the legs. When parts of these clots break off they can travel to the lungs and cause a potentially fatal condition called Pulmonary Embolism or PE. These dangerous and deadly blood clots can form in anyone, but hospitalized patients, those who are on long airplane flights, or anyone who is sedentary for any length of time can be at risk. In this program, we'll see what can be done to prevent both DVT and PE. We'll also see how scientists working with public health experts are finding ways to help people lower their risks of both deep vein thrombosis and pulmonary embolism.
