Tubercle and high-pressure _'s general knowledge of the lung artery
The artery high pressure of lung is a kind of very important complications of tubercle patient, in WHO lung artery was classified under high pressure in 2003, classified the relevant lung artery of of tubercle as one among them under high pressure too. The materials show, the overall ill rate of tubercle and lung artery high pressure of patient does not exceed 5%, but to the later period patient, the incidence of the artery high pressure of lung may be obvious, for instance reports such as Shorr,etc., plan to implement for 363 later periods of lung transfer operation tubercle patient check and find by the right heart conduit, 73.8% of the patients amalgamate artery high pressure of lung.
The scholar thinks, it is mainly each of image credit to amalgamate the tubercle patient of the high pressure of lung artery, or can angry the intersection of disperse and tubercle disease patient that function obviously lower, the majority is studied and finds through many factor analysis, whether artery high pressure of lung and tubercle patient have lung fiber, hypoxemia disease intensity and lung keeping in touch with or disperse function situation not to have clear relevance.
Usually think, the tubercle patient's lung artery high pressure is caused the lung capillary bed to destroy by the lung fiber to cause with hypoxemia disease, but present research shows, the severity, lung fiber and hypoxemia disease intensity of tubercle and lung artery high pressure of patient have no relevance, some can also present the artery high pressure of severe lung while having lung fiber tubercle patient, and the lung artery high pressure can be some early tubercle patients' main behavior, pointing out a tubercle patient may have other mechanisms of causing the artery high pressure of lung. Think, besides the above two factors, may include at present: Specific granulation swollen pathological change involves the lung blood vessel; The enlargement of lymph nodes oppresses the lung artery in the chest; The active substance of blood vessel unusually causes the lung blood vessel to shrink; There are door pulse and high pressure occasionally, cause the artery pressure of lung to increase.
