Case Sharing: Xiao Xu is a company employee, married for almost three years, in August this year, finally made a success. early November, she suddenly felt pain in the left leg, and then take a closer look, than the right leg is much thicker. Received by the emergency department director explained: “left lower extremity venous embolism formation, blood reflux is blocked, there will be lower extremity swelling, pain, dysfunction. The scariest thing is that once the thrombus is dislodged, it will enter the pulmonary artery along the blood circulation, causing pulmonary embolism, which can be life-threatening.” Internationally, the incidence of pulmonary embolism is around 20% statistically. For pregnant Xiao Xu, once the consequences of pulmonary embolism is very serious, for one thing, the drugs used to treat pulmonary embolism may cause placental abruption bleeding, etc., 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 the most prone to lower extremity venous embolism for many reasons, among which increased coagulation in pregnancy with the pregnant uterus compressing the blood flow in the veins of the lower extremities is the main reason. 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 diseases such as heart failure, stroke and hypertension. Due to this lack of knowledge, many people fail to detect and treat venous thrombosis early. In recent years, venous thromboembolism has become a 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 an embolism is a thrombus, which is a mass of blood that has coagulated. Under normal circumstances, blood does not clot in the body. However, blood tends to coagulate and form clots in the following situations. First, slow blood flow in blood vessels; second, damage to the lining of blood vessels; third, increased blood viscosity. These three conditions often interact with each other, forming a vicious circle that eventually leads to thrombosis. The deep veins of the lower limbs have a relatively slow blood flow and are the most common site for thrombosis. How to prevent venous thrombosis? The risk can be effectively reduced by scientific anticoagulation therapy. Jiangzhong Bolok can directly dissolve blood clots, improve ischemic symptoms, and reduce blood viscosity to improve microcirculation and prevent thrombosis. And long-term use will not cause bleeding tendency in hyperfibrinolytic state. Compared with aspirin, Bolok can not only improve the state of platelet aggregation hyperfunction and reduce blood viscosity to prevent thrombosis, but also reduce the content of fibrinogen in the blood, reduce the production of fibrin, and most importantly, activate the patient’s fibrinolytic system, which will not cause gastrointestinal bleeding, and it is safer and more effective. Nearly 10 million cases of venous thromboembolism occur globally every year, and it can be subdivided into deep vein thrombosis (DVT) and pulmonary embolism (PE). Among them, the former mainly occurs in the lower limbs and manifests as pain, usually starting from the popliteal fossa (the diamond-shaped fossa depression behind the knee), and may also manifest as limb swelling (especially in the ankle), redness, localized skin ulcers, and elevated body temperature. However, when these symptoms occur, the condition is usually already serious. Most DVT patients do not have obvious symptoms in the early stage, and about 80% of them are easy to miss the diagnosis. It should be reminded that, in addition to hospitalized patients, undergoing surgeries (especially hip, knee and tumor-related surgeries), long-distance travel (by plane and car), being over 60 years of age, as well as smoking and obesity are all risk factors for venous thrombosis. Some patients are reluctant to exercise after surgery for fear of wound pain and as a result develop blood clots. It is recommended to understand and emphasize the prevention of venous thromboembolism as early as possible to prevent this “thief” of health from succeeding.
