Deep vein thrombosis (DVT) occurs when clots form in the extremities. If pieces of these clots break off and travel to the lungs, pulmonary embolism (PE) can occur. The annual incidence of venous thromboembolism (VTE) in the United States is 600,000 cases. Early diagnosis and treatment are crucial for preventing morbidity and mortality. Death from DVT is attributed to massive PE.
