Venous thrombosis

Veins carry blood back to the heart from the tissues. Blood flowing in the veins is under lower pressure and moves more slowly than blood flowing in the arteries. Blood is therefore more likely to clot in the veins, thus blocking the flow through the veins.
Blood clot formation in the veins is called venous thrombosis. Venous thrombosis most commonly forms in the veins of the legs. Risk factors for venous thrombosis include prolonged bed rest or immobility, as can be necessary after surgery, cancer, and estrogen therapy.
Venous thrombosis can cause swelling and pain of the leg in which it forms. Large clots can also break free and travel to the heart and lungs, where they can cause cardiac arrest and sometimes death. This is called pulmonary embolism.
