Introduction: Venous thromboembolism (VTE) is a disorder of venous reflux, which refers to abnormal coagulation of blood in veins, which completely blocks or blocks blood vessels, mostly in lower limbs. The disease is often acute, with high incidence, high mortality and high misdiagnosis rate. It is a high-risk complication of orthopedic, neurosurgery, thoracic surgery, tumor and other patients, and it is also an important cause of accidents. If the lower limbs suddenly swell, the skin color is red or there is pain in the back of the calf, and there is obvious sense of involvement when walking, and the lower limbs are obviously asymmetrical, it may be that they have lower extremity thrombosis. So how to treat venous thromboembolism?

The treatment of venous thromboembolism includes the following two aspects: first, interventional catheter can be used for thrombolysis in the case of acute venous thrombosis, and inhalation electricity, inhalation electricity and catheter can be used for thrombolysis in the case of deep venous thrombosis of lower limbs. Before this, the inferior vena cava filter should be installed to prevent thrombus from falling off during thrombolysis and electricity absorption, resulting in pulmonary embolism.

Second, chronic venous thrombosis is generally treated with anticoagulation. Low molecular weight heparin was injected subcutaneously during hospitalization, and anticoagulant was taken orally for 3-6 months after discharge, and the hospital was reviewed regularly. According to whether the thrombus will dissolve again, decide whether it is necessary to extend the treatment time. For venous thrombosis of lower limbs, whether it is acute or chronic, elastic socks should be worn to avoid the recurrence of thrombosis and alleviate the symptoms of limb swelling.

In addition to treatment, patients are also reminded to maintain a low-fat and high-fiber diet in their daily lives, and to quit smoking and drinking. Try to change several alarm clocks quietly, comfortably and neatly, keep the room temperature at about 25 degrees, and people with low skin temperature of limbs should pay attention to keep warm. Try to avoid sedentary, do more activities, keep the stool unobstructed and prevent constipation. Patients in bed actively or passively raise their legs above the heart to promote venous return and ankle pump movement.
