DVT prevention refers to strategies employed to reduce the risk of deep vein thrombosis, a condition where blood clots form in deep veins, typically in the legs. It is crucial in clinical practice as DVT can lead to serious complications such as pulmonary embolism, which can be life-threatening. Key preventive measures include pharmacological interventions, such as anticoagulants, and non-pharmacological approaches like compression stockings and early mobilization after surgery or prolonged immobility.
