The pathology of lung abscess displays _'s general knowledge
Pathological change blocks the detailed bronchus for the pollutant including pathogen in early period, it causes some lung tissue suppurative inflammation that the pathogen breeds, then form small vascular inflammation thromboembolism and make the lung organize suppurating rapidly, necrosis, form lung abscess. Begin some light regional necrosis form abscess more, then pathological change can to expand around, even exceed splitting and infringing neighbouring lung section among the leaves, form single bigger abscess. It causes the tension to increase in the suppuration that the liquid of suppuration of liquefaction is gathered, break to the bronchus routedly, the suppuration liquid part is got rid of, form flat suppuration of liquid, common residual necrosis tissue of surface of cavity wall.
Can be seen and expectorate a large amount of suppuration phlegm on clinic. The mirror is examined and can be seen the infiltration with neutral cells of a large number of. If fiber pleurisy of the limitation can take place in the neighbouring pleura of abscess, cause the pleura adhesion. If abscess lies in tension abscess of the lung edge portion, it is so routed that the pleura get to break. Acute lung abscess is passed and treated positively rationally, if the trachea is unobstructed, then the liquid of suppuration is discharged by the angry way, and suppuration fades, pathological change totally absorbs or only has the fibrous scar of small quantity left.
If the acute one of lung abscess fails to control in time, will not treat completely, it is not smooth that the bronchus is guided, course of disease delay 3 month more than abscess that can heal, call that chronic abscess. Pathology vary to remain in the intersection of suppuration and by a large number of the intersection of necrosis and organization, suppuration one of fibers of wall organizes hyperplasia, suppuration increases the thick companion's granulation tissue and takes shape in one of walls.
The remaining blood vessel lose support that the lung organizes in necrosis is organized in the forming process of lung abscess, by hemangioma of forming partly,this in being repeated, a large number of foundations pathologics of hemoptysis. Of the intersection of wall and surface granulation organize the blood vessel to be relatively abundant, can also cause and cough the blood phlegm of suppuration or spit blood in a small amount. The above-mentioned pathology of lung abscess can involve the detailed bronchus around while changing, it is out of shape and expanding to cause, this too causes chronic lung abscess to spit blood on the pathologic foundation.
