The main treatment for venous thrombosis is medication, but for some urgent cases, surgery can be chosen, and other treatments can be used to improve the overall efficacy of the disease. 1. Pharmacological treatment: all the drugs used need to be used under the guidance of a doctor, and if there is any discomfort in the process of using them, it is necessary to consult a doctor in time to deal with it. (1) Non-steroidal anti-inflammatory drugs. Such as ibuprofen, meloxicam, diclofenac, etc., with anti-inflammatory and pain relief, reduce the probability of recurrence. Since the cause of venous thrombosis may be related to vascular injury, etc., this drug needs to be selected according to the condition. (2) Anticoagulant drugs: such as warfarin, heparin, rivaroxaban, etc., are the basic drugs for people with venous thrombosis, which have the effect of stopping platelet agglutination and preventing thrombosis. (3) Thrombolytic drugs: such as streptokinase, urokinase, etc., can dissolve the thrombus that has formed in the vein. The specific choice of medication needs to be decided by the doctor. 2. Surgical treatment: For some people who may have pulmonary embolism and other emergencies, catheter thrombectomy is needed to urgently relieve acute embolism and restore blood flow in the veins, thus saving the patient’s limb and life. The use of inferior vena cava filters can also be added to prevent thrombus dislodgement and obstruction of vital organs. 3. Other treatments: Oxygen inhalation as needed to maintain the oxygen saturation level of the patient; elevation of the lower limbs to reduce the swelling of the lower limbs; compression therapy to promote venous return and alleviate varicose veins; etiological treatments, such as timely treatment of fracture for those who have fractures and preventive anticoagulant medication. It is recommended that the people concerned should seek medical treatment in time.
