Venous thrombosis can be divided into superficial vein thrombosis, which is mainly caused by superficial phlebitis, and deep vein thrombosis, which is mainly caused by blood stasis and hypercoagulability of blood. Deep vein thrombosis is more serious and common in clinical practice, and usually requires bed rest to avoid dislodging and embolization of other parts of the body, as well as thrombolysis and embolization treatment, such as drug anticoagulation, interventional thrombolysis, and surgical embolization. The focus of superficial vein thrombosis treatment is usually to remove the triggering factors, then general treatment and observation, and if necessary, medical treatment. Deep vein thrombosis 1, drug anticoagulation: Patients with deep vein thrombosis can have local pain, swelling, and increased activity in the early stage, and even have obvious limb color turning purple, which requires timely medical treatment. If deep vein thrombosis is diagnosed, drug anticoagulation therapy can be administered at an early stage to avoid more serious conditions. Usually the doctor will decide the type of medication according to the time of thrombosis, such as heparin, warfarin, streptokinase, urokinase, etc. Some patients can be relieved by timely medical treatment, but some patients may not be treated timely, and drug anticoagulation can only play a certain auxiliary role; 2, interventional thrombolysis: if the patient is not effective after drug anticoagulation treatment, further interventional thrombolysis can be taken. treatment. Doctors can use medical instruments, such as CT positioning, ultrasound, etc., to place interventional devices into the veins where thrombosis occurs and inject drugs or place stents to relieve the condition. However, this operation method is invasive, and it is necessary to pay attention to prevent wound infection after the operation. 3.Surgical thrombosis: If the treatment effect of patients with deep vein thrombosis is not obvious after the above methods, or the embolus is dislodged and blocked the blood vessels of lung and brain, it is necessary to carry out surgical thrombosis in time to relieve the disease and complications. After surgery, patients need to take medication or life care according to medical advice in order to effectively promote recovery. Superficial vein thrombosis 1, remove the triggering factors: there are more factors that can cause superficial vein thrombosis, such as superficial phlebitis, long-term intravenous placement or infusion of irritating fluids. In addition, it is usually related to smoking, so patients should quit smoking; 2. General treatment and observation: such patients can rest to relieve the pain at the onset and elevate the affected limb, or take anti-inflammatory and pain-relieving drugs, and some patients can use hot compresses to relieve the pain caused by vascular spasm due to venous inflammation. If the superficial vein thrombosis occurs in the limb part, you can also wear elastic stockings to use its elastic gradient to relieve the pressure of varicose vein and observe the effect; 3.Medical treatment: If the superficial vein thrombosis is found to be more serious or occurs in more important vein parts, such as saphenous vein, the patient needs medical treatment, which may use medicine or may need surgery, depending on the patient’s own condition.
