The doctor said, the thrombus stuck in it’s most dangerous, alert to the alarm signal – Sohu Sohu health Wen Na people every organ may occur such as thrombosis, heart blood vessel blockage can cause myocardial infarction, cerebral vascular thrombosis will cause cerebral infarction and so on, everyone on the "heart attack", "cerebral thrombosis" may not strange, you heard about another very common thrombotic disease, pulmonary embolism? In fact, pulmonary embolism is the second only to coronary heart disease, hypertension, heart disease, is an important cause of sudden death. Pulmonary thromboembolism occurred, 3 of which died within 1 hours after the onset of the disease, and the mortality rate was more than 15% months after operation in the 11% months. So, what is pulmonary embolism? What kind of people are prone to pulmonary embolism? How to prevent pulmonary embolism? Got pulmonary embolism how should treat? Recently, in the respiratory center, cardiovascular center in the hospital will be held in conjunction with the health education and disease consultation of thrombotic diseases, respiratory and critical care medicine, two department deputy chief physician is Wanjun pulmonary embolism knowledge in-depth explanation. Patients with high risk of pulmonary embolism in normal physiological conditions, blood circulation in the blood vessels, do not produce thrombus. If there is a certain disease or other abnormal circumstances, blood vessel injury, slow blood flow or blood clots. Similar to the "myocardial infarction" and "cerebral thrombosis", pulmonary embolism is also a kind of thromboembolism, that is, the pulmonary blood vessels (pulmonary artery) is blocked by thrombus. In most cases, the blockage of the pulmonary artery is from the deep veins of the lower extremities; in a few cases, the thrombus may also come from other parts of the body, such as the upper extremity veins, pelvic veins, etc.. There are three basic factors of thrombosis: blood stasis, hypercoagulability and endothelial injury. These three factors are the basic conditions for the incidence of pulmonary embolism. So what happens in everyday life under these three conditions? First of all, blood stasis mainly occurs in some activities to reduce or even no activities of people, the hospital is the primary factor of venous thrombosis associated with death and disability, venous thrombosis in 60% is related to hospitalization (occurring during hospitalization or after discharge), such as trauma, surgery and Department of orthopedics patients after bed for a long time, the blood flow is slow to eventually block the pulmonary artery thrombus formation. In addition, sedentary, long time by plane, driving, long time use of computers, playing mahjong, watching TV is also a common cause of pulmonary embolism. Secondly, the hypercoagulable state mainly refers to some pathological or physiological conditions, composition of coagulation in the blood increased, visible in patients with malignant tumor, pregnancy and perinatal women, the use of hormone replacement therapy for menopausal women or menopausal women. In addition, patients with lower limbs, abdomen, pelvis, knee injury or surgery, inflammatory bowel disease, nephrotic syndrome and severe infection induced sepsis and hereditary thrombophilia also may cause hypercoagulable state; thirdly, the inner vascular endothelial injury, refers to the internal skin damage, so as to make this the composition of blood coagulation and aggregation thrombosis, seen in trauma, such as lower extremity injuries can lead to vascular endothelial damage, once because of strength and fitness cause vascular injury secondary to thrombosis of the lower extremity were also endothelial injury can also be)
