Drug treatment: patients with lower extremity venous thrombosis can take oral anticoagulant drugs such as low molecular heparin sodium, warfarin, rivaroxaban and other anticoagulant drugs for anticoagulant treatment as prescribed by doctor. In addition, patients can also follow the doctor’s instructions to use urokinase, bacitracin and other thrombolytic drugs. 2. Surgical treatment: patients with lower extremity venous thrombosis can undergo surgical treatment, such as lower extremity interventional thrombus aspiration, lower extremity venous cannulation thrombolysis, thrombectomy and other surgical methods. 3. General treatment: when patients with lower extremity venous thrombosis experience discomfort, they should rest in bed, elevate the affected limbs, and avoid massaging and extruding the affected limbs, which may cause thrombus dislodgement.
