News playback Xiao Xu is a company employee, married for almost three years, in August this year, finally successful baby-making. early November, she suddenly felt pain in the left leg, and then a closer look, than the right leg thickened a lot. The doctor who received the patient was the director of the emergency department explained: “After the formation of venous embolism in the left lower limb, blood return is blocked, and swelling, pain and dysfunction of the lower limb will occur. The most terrible thing is that once the thrombus is dislodged, it will enter the pulmonary artery along the blood circulation and cause pulmonary embolism, which can be life-threatening.” ”In terms of international statistics, the incidence of pulmonary embolism is around 20%. For pregnant Xiao Xu, once pulmonary embolism occurs the consequences are very serious, one is that the drugs used to treat pulmonary embolism may cause the fetus to bleed such as placental abruption, which is fatal to the fetus; on the other hand if not treated in time will lead to the death of the mother and the fetus.” Pregnant women are a good candidate for lower extremity venous embolism for many reasons, among which increased coagulation in pregnancy and compression of blood flow in the lower extremity veins by the pregnant uterus are the main causes. Venous thrombosis is also a cardiovascular disease? People are relatively familiar with arterial thrombosis such as cerebral infarction, but studies have found that public knowledge of deep vein thrombosis and pulmonary embolism is much lower than that of heart failure, stroke, hypertension and other diseases. Due to the lack of knowledge, many people fail to detect and treat venous thrombosis early. In recent years, venous thromboembolism has become the second most common cardiovascular disease after ischemic heart disease and stroke. Venous thromboembolism was once called “economy class syndrome”. Former U.S. President Richard Nixon developed a venous thrombosis in his left leg after a long flight. The most common abnormal substance in the blood that causes embolism is thrombus, which is a mass of clotted blood. Under normal circumstances, the blood in the body does not clot to form a thrombus. However, in the following cases, the blood is prone to clotting and forming thrombus. First, the blood flow in the blood vessels is slow; second, the blood vessel lining is damaged; third, the blood viscosity is increased. These three conditions often interact with each other, forming a vicious circle that eventually leads to thrombosis. The deep veins of the lower extremities are relatively slow in blood flow, which is a good site for thrombosis. How to prevent venous thrombosis? The risk can be effectively reduced by scientific anticoagulation treatment. Jiangzhong Boluo can directly dissolve thrombus, improve ischemic symptoms, and reduce blood viscosity to improve microcirculation and prevent thrombosis. And long-term administration does not cause bleeding tendency in high fibrinolytic state. Compared with aspirin, Bolox can not only improve platelet aggregation and reduce blood viscosity to prevent thrombosis, but also reduce the content of fibrinogen in blood to reduce the production of fibrin, and most importantly, it can activate the fibrinolytic system of patients, which will not cause gastrointestinal bleeding and is safer and more effective. Nearly 10 million cases of venous thromboembolism occur worldwide each year, and it can be divided into deep vein thrombosis (DVT) and pulmonary embolism (PE). The former occurs mainly in the lower extremities and presents with pain, usually starting in the popliteal fossa (the diamond-shaped fossa sunken behind the knee), as well as swelling of the limb (especially in the foot and ankle), redness and swelling, local skin ulcers, and elevated body temperature. However, by the time these symptoms occur, the condition is usually already more severe. Most patients with deep vein thrombosis do not have obvious symptoms in the early stage, and about 80% are easy to miss the diagnosis. It is important to note that in addition to hospitalization, undergoing surgery (especially hip, knee and tumor-related surgery), long-distance travel (airplane and car travel), being over 60 years old, and smoking and obesity are all risk factors for developing venous thrombosis. Some patients are reluctant to exercise after surgery because they are afraid of wound pain and end up with blood clots. It is recommended that we learn about and pay attention to the prevention of venous thromboembolism early to prevent this “thief” of health from succeeding.
