Different stages of venous thrombosis are treated differently, but in general, anticoagulant drugs are needed to treat the disease, and commonly used and effective oral drugs are usually warfarin to anticoagulant treatment. In the early stage of DVT, patients can be treated with drugs, such as intravenous heparin sodium; oral drugs are usually warfarin for anticoagulation, and thrombolytic drugs, such as urokinase, streptokinase, etc. If the effect of drug anticoagulation is not good, the patient can be treated with oral drugs, such as urokinase and streptokinase. If the effect of drug anticoagulation is unsatisfactory, interventional thrombolytic therapy or surgical thrombolytic therapy can be performed to avoid the occurrence of complications. Patients with superficial venous thrombosis usually have small localized soft tissue swelling, which usually does not require oral medication, but is usually treated with localized topical medication and cessation of triggers. Patients with venous thrombosis should seek medical attention as soon as possible, and the doctor should choose the appropriate treatment according to the patient’s condition, and the medication should be applied under the doctor’s guidance.
