's general knowledge of high-pressure cause of disease of the lung artery
1.The artery blood flow volume of lung increases
(1)The ones that shunt right on the left are inborn and cardiovascular and unusual: Atrial septal defect, ventricular septal defect, artery conduit have not been closed, the permanent artery has been dry
(2)The acquired character will be shunted in the heart the day after tomorrow: Main aneurysm breaks or aorta Valsalva aneurysm is broken into right ventricle or atrium dextrum Nan, the interventricular septum punches after myocardium infarction (defect)
2.The resistance of blood vessel increases around the lung
(1)The lung blood vessel bed shrinks: Lung artery thromboembolism that various reasons cause
(2)Lung artery tube wall pathological change:
Lung arteritis: Calcium calmness, Renaud's phenomenon that Renaud's syndrome, scleroderma limitation are in the skin, point (toe) Scleroderma and capillary expand syndrome (CREST syndrome) Rheumatoid arthritis, systemic lupus erythematosus, multiple the intersection of neuritis and leather the intersection of myositis and the intersection of granulation and swollen the intersection of arteritis and acidophil increase disease, loud arteritis.
The artery high pressure of primary lung: The clump a little thrombotic pulmonary vein of vascular disease of lung stops up the disease
The lung artery is inborn and narrow.
(3)The quality among the lung fiber or lung granulation is swollen: Person who fill the air the intersection of quality and fiber take radioactive the intersection of lung and the intersection of fiber and take, millet grains of the intersection of sex and the intersection of pulmonary tuberculosis and pneumoconiosis, lung cancer lung sac fiber it takes to be specially the intersection of hemosiderin and calm disease,etc. of taking place etc. among the lung.
(4)Hypoxemia disease causes vascular convulsion of the lung:
Chronic obstructive pulmonary tuberculosis: Chronic bronchitis and pulmonary emphysema, bronchus asthma.
Breathe the movement obstacle: Disease, multiple poliomyelitis of thoracic deformity of the pleura, amyotrophy, obesity
Oxygen deficiency of plateau
(5)The viscosity of blood changes: Blood plasma viscosity increase and erythrocyte increase disease, erythrocyte person who gather increase, hardness of erythrocyte increase
3.The venous pressure of lung increases
(1)The pulmonary vein stops up: It is narrow that mediastinal tumour or granulation is swollen and ill, mediastinal to hinder inflammation, inborn pulmonary vein
(2)Heart disease Nan: The left heart function is not complete, mitral stenosis or lock the complete, hearts of room three of calcificated, left room mucus tumour of bicuspid valve ring.
