KnowVTE - Đánh giá dự phòng huyẠt khối tĩnh mạch description

Venous thromboembolism (VTE) refers to a blood clot that starts in a vein. It is the third leading vascular diagnosis after heart attack and stroke.
- Deep vein thrombosis (DVT) Deep vein thrombosis is a clot in a deep vein, usually in the leg. DVT sometimes affects the arm or other veins.
- Pulmonary embolism (PE) A pulmonary embolism occurs when a DVT clot breaks free from a vein wall, travels to the lungs and then blocks some or all of the blood supply. Blood clots originating in the thigh are more likely to break off and travel to the lungs than blood clots in the lower leg or other parts of the body.
