DVT prophylaxis refers to medical interventions aimed at preventing deep vein thrombosis (DVT), a condition where blood clots form in deep veins, typically in the legs. These strategies are crucial for patients at increased risk, such as those undergoing surgery, with limited mobility, or certain medical conditions. Prophylactic measures include mechanical methods (e.g., compression stockings, intermittent pneumatic compression) and pharmacological agents (e.g., anticoagulants) to reduce the risk of clot formation and subsequent pulmonary embolism.
