Venous Thromboembolism

Venous thromboembolism (VTE) is a condition in which a blood clot forms most often in the deep veins of the leg, groin or arm (known as deep vein thrombosis, DVT) and travels in the circulation, lodging in the lungs (known as pulmonary embolism, PE). Together, DVT and PE are known as VTE - a dangerous, potentially deadly medical condition.

Types of Thrombosis Deep vein thrombosis (DVT): A blood clot that forms in a deep vein, usually the leg, groin or arm. Pulmonary embolism (PE): A blood clot that occurs when a DVT clot breaks free from a vein wall and travels to the lungs blocking some or all of the blood supply. PE can often be fatal. DVT + PE = VTE: DVT and PE are collectively referred to as VTE.

VTE is a leading cause of death and disability worldwide. A comprehensive scientific review by the WTD steering committee revealed that 10 million cases of VTE occur annually – across low, middle and high income countries.
