Venous thrombosis of the lower extremities is a common peripheral vascular disease and a multifactorial disease. Stagnant blood flow, blood hypercoagulation and vascular wall damage are the three main causes of the formation of the disease, but a single factor often cannot cause the disease independently, and it is often the combination of two or three factors that causes the formation of venous thrombosis of the lower extremities. Patients may consider surgery in the absence of extensive metastasis, when the patient is still in good health and without serious complications, but amputation is required when bone or major blood vessels and nerves are involved. Traditional Chinese medicine treatment for advanced venous thrombosis of the lower extremities can play a comprehensive role in controlling the disease, improving the patient’s own immune function, improving the physical condition, and reducing the occurrence of complications and relieving and treating serious symptoms. At present, the treatment technology for lower limb venous thrombosis has been relatively mature, commonly used treatment methods include: a. Treatment of thrombotic superficial phlebitis 1. Avoid prolonged standing or sitting. 2.Medication: painkillers include: pautazone, indomethacin (anti-inflammatory pain), piroxicam (inflammation and pain Xikang), aspirin, etc. Antibiotic treatment is generally unnecessary. When the superficial vein thrombosis is extensive in the acute stage, anticoagulation therapy such as low molecular heparin is recommended to avoid the spread of thrombus to the deep vein system leading to pulmonary embolism. Second, the treatment of deep vein thrombosis 1, general treatment Bed rest, elevate the affected limb above the level of the heart, about 20-30cm from the bed, knee joint slightly flexed position. Keep the bowel movement smoothly, avoid the thrombus dislodged by forceful defecation which leads to pulmonary embolism. After getting up, wear long elastic stockings for 6 weeks to 3 months. 2, anticoagulation therapy (1) heparin: intravenous heparin to make the partial thromboplastin time (APTT) reach 1.5-2 times of normal, and maintain the treatment for 5-7 days. However, the dose of intravenous heparin is difficult to control, and inadvertent grasp may cause bleeding, so the safer method can be used low molecular weight heparin, subcutaneous injection. (2) Warfarin: Warfarin is given orally after 5 days of heparin therapy until the coagulation INR index (prothrombin time, PT) reaches 2-2.5 times the normal level. Thereafter, maintenance doses are given for 3-4 months. 3, Thrombolytic therapy commonly used drugs are urokinase, streptokinase and fibrinolytic enzymes. Since they are more likely to cause bleeding, their long-term efficacy is not better than that of anticoagulation therapy, so they are generally used only when combined with pulmonary embolism. For patients who cannot be treated with anticoagulation and have a low risk of pulmonary embolism, elevation of the limb and local heat application can be tried. 4.Interventional treatment: divided into permanent and temporary vena cava filter implantation. Warm tip: The use of Chinese medicine treatment can also well improve the patient’s immune function, improve the patient’s own ability, promote the protection of the patient’s normal organism function, is the most acceptable and safe treatment method for patients. Therefore, whether it is conservative treatment alone, or combined with Western medicine treatment methods for comprehensive treatment, Chinese medicine treatment methods are indispensable means.
