What causes a venous thromboembolism?

BLOOD STAGNATION. There are many risk factors for deep venous thrombosis (dvt) or blood clots including but not limited to: immobility, age over 50, some cancers, recent surgery, pregnancy, tobacco abuse, blood clotting disorders. The blood pools and forms a blood clot which then has a potential to move to the lungs and cause something potentially more damaging called a pulmonary embolism (pe).
