Venous thromboembolism (VTE) is a term that encompasses deep vein thrombosis (DVT) and pulmonary embolism (PE).
Deep vein thrombosis (DVT) is the formation of a blood clot (thrombus) within a deep vein. It commonly occurs in the thigh or calf. Deep vein thrombosis can develop after any major surgery. People who have surgery on the legs and hip are especially at risk.
A pulmonary embolism (PE) is a clot that breaks free and travels through the veins. If it reaches the lungs, it can block the flow of blood to the lungs and heart. A pulmonary embolism is a dangerous condition that can even lead to death.
