Answer

Prevention of deep venous thrombosis (DVT) has long been studied in various clinical situations with varying degrees of success. Primary prophylaxis is directed toward acting on one or more components of the Virchow triad, affecting blood flow, coagulation, or vessel wall endothelium. Methods of prophylaxis may be generally divided into mechanical and pharmacologic. Many pharmacologic agents are currently available to prevent thrombosis. Agents that retard or inhibit the process belong under the general heading of anticoagulants. Agents that prevent the growth or formation of thrombi are properly termed antithrombotics and include anticoagulants and antiplatelet drugs, whereas thrombolytic drugs lyse existing thrombi.
