Lower extremity venous thrombosis with more swollen feet after wearing compression stockings is a posterior post-deep vein thrombosis syndrome, which is classified as occlusive, partially recanalized, recanalized, and recanalized. According to the classification of symptomatic treatment. After deep vein thrombosis, with the progress of thrombus mechanization as well as recanalization process. The obstruction of venous return gradually decreases. Wearing compression stockings can cause venous valves to compress and accelerate blood flow. However, if the swelling of the legs increases, for the post DVT syndrome. Destruction of the deep vein valves causes the thrombus to move from the acute to the chronic phase. It causes increased symptoms of venous reflux. If occlusion is predominant, non-surgical treatment such as anticoagulation and thrombolysis is the mainstay. The iliac and femoral veins are occluded while the femoral vein is patent. After the condition is stabilized, suprapubic saphenous vein cross diversion is done. For femoral vein occlusion, saphenous vein femoral-popliteal vein bypass is used clinically. In case of complete recanalization, it is treated by surgical approach of primary deep vein valve closure insufficiency. If there is a lower extremity venous thrombosis after wearing compression stockings, the legs and feet are more swollen. It is necessary to consult a doctor as soon as possible and follow the doctor’s instructions to avoid aggravating the condition.
