Deep vein thrombosis (DVT) is a vascular disorder characterized by the formation of blood clots within the deep venous system, predominantly affecting the lower extremities. These intravascular thrombi typically originate in the venous valves or the venous sinuses of the calf muscles. The pathogenesis of DVT involves a complex interplay of Virchow’s triad, which includes endothelial injury, abnormal blood flow, and hypercoagulability. Predisposing risk factors encompass a wide spectrum, ranging from surgical procedures, prolonged immobilization, and trauma to inherited thrombophilias, malignancy, and hormonal contraceptive use. Clinically, patients may present with unilateral leg pain, swelling, erythema, and increased warmth.
Elastic compression stockings, also referred to as graduated compression hosiery, constitute a fundamental component of preventive and therapeutic interventions for various vascular and circulatory conditions. These specialized garments are meticulously engineered from elasticized textiles, meticulously calibrated to exert graduated pressure along the lower extremities. The primary objective of this pressure gradient is to enhance venous return, mitigate venous stasis, and ameliorate symptoms associated with venous insufficiency. By facilitating optimal blood flow dynamics, these stockings effectively counteract venous pooling, edema, and the formation of varicosities. Notably, the pressure distribution is highest at the ankle and gradually diminishes proximally, thereby promoting efficient blood circulation
After surgery, Patients are prone to DVT, and one of the most effective ways is Elastic compression stockings.
According to NNT.com Elastic compression stockings have a NNT of 7 and 1 in 7 were helped after surgery to prevent DVT.
