Venous Thromboembolism

A venous thrombosis is a blood clot (thrombus) that forms within a vein. Thrombosis is a medical term for a blood clot occurring inside a blood vessel. A classical venous thrombosis is deep vein thrombosis (DVT), which can break off (embolize), and become a life-threatening pulmonary embolism (PE). The conditions of DVT and PE are referred to collectively with the term venous thromboembolism.
