The intersection of pulmonary embolism and cause of disease and have illness coming on the intersection of mechanism and the intersection of _ and general knowledge
Cause of disease and having illness coming on in the mechanism
(1) Thrombotic pulmonary embolism is often amalgamation disease of phlebothrombosis. The embolus usually comes from the deep veins of lower extremities and pelvis, cause thromboembolism to the lung artery through circulating. But seldom come from upper limbs, head and shank vein. The blood flow is silted up, it is a thrombotic promotion factor that the blood increases and damages with the intravenous inner cover. So, wound, lie in bed for a long time, variceal intravenous intubate, pelvis and hip operation, fat, diabetes, contraceptive, other blood coagulation of reason mechanism hyperfunction, etc, phlebothrombosis of easy kindling. The early thrombus is crisp, in addition, the fine function of dissolving the system, it is being highest the danger of pulmonary embolism takes place in so thrombotic first several days.
(2) Heart disease is the most common reason of pulmonary embolism of our country, accounts for 40%. Several spreads all over all kinds of heart disease, amalgamate the room quiver, in heart failure and inflammation person's morbidity of membrane in the bacterial heart of subnormal temperature is relatively high. See at most with a of thrombus of right heart, a few also comes from the venous system. Bacterial embolus besides seeing membrane inflammation in the subnormal temperature bacterial heart, also can infect, cause because of pace maker. The former infective embolus come from tricuspid valve mainly, the intersection of bicuspid valve and superfluous living beings, patient of heart, can left heart shunt, enter right heart and reach the intersection of lung and artery by defect since first once in a while.
(3) Tumour is for the sake of second in our country, accounts for 35%, it is high than foreign 6% to be far. Relatively common with lung cancer, digestive system tumour, fine hair cancer, leukemia,etc.. It is the tumour bolt that malignant tumour erupts only about 1/3 of pulmonary embolism simultaneously, the others are the thrombus. By inference there may be kinase of blood coagulation (thromoboplastin) in tumour patient's blood And the other materials such as histone, cathepsin and protein hydrolase,etc. that can activate the blood coagulation system, so tumour patient's pulmonary embolism incidence is high, even can be its symptom now.
(4) Gestation and give birth to pulmonary embolism it several times as much as whom ages mates to be pregnant woman in pregnant woman, postpartum and the postoperative incidence of caesarean birth is the highest. Press, increase with hormone relaxing smooth muscle and basin vein of blood vessel, pigeonholing and can cause the intravenous blood flow slowly in the abdominal cavity when the gestation, change the blood rheology characteristic, aggravate phlebothrombosis. In addition the intersection of companion and the intersection of blood coagulation and factor and blood platelet increase, blood plasma plain and original and the intersection of blood plasma and plain albumen dissolve the systematic activity, lower. But these changes compare without having absolute difference with the pregnant woman without thromboembolism of thrombus. Thromboembolism of amniotic fluid is the serious complication giving birth to one too.
(5) It is other and other cause of disease when it is rare long bone fracture to last thromboembolisms fat,contingency and reduce pressure there aren't disease, parasite and foreign matter thromboembolism. Without obviously inspiring the factor, should also consider heredity anticoagulatory factor reducing or plasminogen activates the increase of inhibitor.
