What is the anticoagulant treatment for venous thrombosis?

Anticoagulation therapy for venous thrombosis is designed to prevent blood coagulation in the veins, in order to relieve and treat venous thrombosis. Generally, patients who use anticoagulant treatment for venous thrombosis need to do so for a long time, because this is the only way to inhibit the deterioration of the disease. Some patients suffer from venous thrombosis due to surgery. These patients need about three months of venous thrombosis anticoagulant treatment, which is a relatively effective cycle. Venous thrombosis and anticoagulation is a relatively common disease, and the chance of occurrence is even higher in certain positions, so friends should pay more attention.

1. Long-term or extended anticoagulation therapy

1. For patients with proximal DVT or PE, long-term anticoagulation (3 months) is recommended for patients who have not received anticoagulation therapy. (Recommendation level 1B)

2. For patients with leg DVT or PE who do not have cancer, dabigatran, rivaroxaban, apixaban, or edoxaban are recommended as long-term anticoagulant treatment drugs, with priority over vitamin K antagonists (recommendation level 2B). If such patients cannot receive dabigatran, rivaroxaban, apixaban, or edoxaban, vitamin K antagonists are recommended, with priority over low molecular weight heparin (LMWH) (recommendation level 2C).

3. For patients with leg DVT or PE and cancer (cancer-related embolism), LMWH is recommended as a long-term anticoagulant therapy, with priority over vitamin K antagonists, dabigatran, rivaroxaban, apixaban, and edoxaban (recommendation level 2C).

4. For patients with leg DVT or PE who have been treated for 3 months, there is no need to change the anticoagulant (grade 2C).

2. Duration of anticoagulant therapy

1. For patients with proximal leg DVT or PE induced by surgery, 3 months of anticoagulation is recommended over short-term anticoagulation, anticoagulation for 6 months or longer, or extended anticoagulation (grade 1B).

2. If the patient suffers from proximal leg DVT or PE caused by non-surgical factors, 3 months of anticoagulation treatment is recommended, which is preferred over short-term anticoagulation treatment or anticoagulation treatment lasting 6 months or longer (recommendation level 1B); if the patient has a low-to-moderate risk of bleeding events, 3 months of anticoagulation treatment is generally preferred over extended anticoagulation treatment (recommendation level 2B); if the patient has a higher risk of bleeding events, 3 months of anticoagulation treatment is recommended (recommendation level 1B).

3. If the patient has isolated distal DVT, 3 months of anticoagulation is generally preferred over short-term anticoagulation (grade 2C), 6 months or longer, and extended anticoagulation (grade 1B).
