Blood clots can break apart and travel through the bloodstream, blocking blood flow to vital organs. VTE includes DVT, a blood clot in a deep vein (usually in the leg), and PE, a blood clot in the lung. Both are serious, life-threatening - but often preventable - conditions. Patients undergoing major orthopedic surgery are at high risk for VTE because during hip or knee replacement procedures, the large veins of the leg that carry blood back to the heart can be damaged, significantly increasing the risk of developing a clot. In fact, venous blood clots occur in 40-60 percent of patients undergoing major orthopedic surgery who do not receive preventive care. In the five largest EU-member states, approximately 450,000 total hip - and approximately 300,000 total knee replacement surgeries are being conducted annually. In the EU, there are in excess of 1.5 million blood clot events annually and these are responsible for killing some 544,000 people each year. About rivaroxaban
