Tshawb fawb yog ib hom kev txheej txheem ntawm cov kab mob

Kev xa tawm yog kis ntawm tus kab mob kis los yog qog hlwb los ntawm tus thawj coj ntawm tus kab mob thoob plaws hauv tag nrho lub cev los yog tus kab mob. Qhov no yog ua los ntawm cov ntshav khiav thiab lymphatic system. Tom qab nthuav, muaj feem ntau yog ib tug txheej txheem ntawm generalization, uas yog kev loj hlob ntawm ntau foci. Cov kev tshwm sim thib ob yog hu ua metastases.

Hom foci ntawm kab mob thiab lawv cov yam ntxwv

Lub xub ntiag nyob rau hauv lub cev ntawm foci nrog qhov loj ntawm pathological ntxoov ntxoo los ntawm 1 mus rau 10 mm txhais tau hais tias muaj nthuav. Cov no tej zaum yuav yog qhov chaw uas txawv hauv kev pathogenesis thiab cov qauv cev nqaij daim tawv. Lawv yog cov mob thiab tsis yog-inflammatory, fibrotic. Feem ntau, lawv tuaj yeem ua ib pawg ntawm cov nqaij thiab cov hlwb. Nyob rau hauv lub tshav pob ntawm inflammatory foci ib tug txheej txheem ntawm perifocal cim tshwm. Tsis tas li ntawd, cov chaw no muaj cov khoom ntawm kev sib koom tes. Nyob rau tib lub sijhawm, lawv pib ua zoo li tus kab mob infiltrative-pneumonic. Thaum lub ntsws raug mob lawm, ob sab kab mob nyias nyias. Ntawm no peb yuav tsum hais qhov txawv ntawm qhov kev kuaj mob. Yav dhau los, cov txheej txheem xws li feem ntau hu ua diffuse pulmonary kab mob. Txawm li cas los, tsis tas yuav muaj tag nrho yeej. Hauv qhov no, lub npe "tshaj tawm" nyob rau hauv cov ntaub ntawv no yog tsim nyog. Kev hloov ntawm qhov no yuav tsis muaj qhov sib txawv.

Cov tsos mob

Kev xa tawm yog kev xoo hluav taws xob txhais tias muaj txog li ntawm 100 yam kab mob sib txawv. Lawv tuaj yeem tshwm sim rau txhua hom kev mob tshwm sim. Dissemination hauv lub ntsws mas feem ntau yog nrog los ntawm kev txhim kho cov txheej txheem ntawm pleura. Cov tsos mob yog ib yam xwm txheej. Nyob rau hauv inflammatory kab mob muaj qaug cawv syndrome thiab hypoxia. Tawm tsam tom qab ntawm disseminated ntsws cancer thiab carcinomatosis - pa tsis ua hauj lwm, progressing nrog ntxiv kev loj hlob ntawm pathology. Pulmonary nthuav tawm tsis yooj yim rau kev tshawb nrhiav. Tias yog vim li cas thiaj muaj qhov siab qhov muaj tseeb ntawm qhov yuam kev. Yog xav paub tseeb tias muaj tseeb, kev kuaj tiav ntawm cov neeg mob yog tsim nyog.

Kev faib tawm ntawm pathologies

Cov kab mob hauv qhov kev nthuav tawm tshwm sim yog:

- Alveolitis (lom fibrosing, exogenous allergic alveolitis, Hammen-Rich syndrome, microlithiasis, proteinosis);

- granulomatosis (pneumoconiosis, sarcoidosis, disseminated tuberculosis, pneumomycosis, histiocytosis);

- o nrog mob qog formations (carcinomatosis, bronchoalveolar, metastatic cancer);

- tsawg tus kab mob (Goodpasture lub syndrome, idiopathic pulmonary hemosiderosis, leiomyomatosis);

- tus mob fibrosis, uas tsim nyob rau hauv lub yeej ntawm lwm yam kabmob thiab lub tshuab (collagen, hluav taws xob puas tsuaj, cardiogenic sclerosis, zoo li sclerosis nrog daim siab mob).

Cov tsos mob

Nrog rau qhov dav dav, nws muaj cov cim qhia ntawm kev txhim kho ntawm cov txheej txheem faib tawm. Kev paub thiab lub peev xwm los lees paub lawv zoo heev rau txoj kev kuaj mob. Thaum koj muaj teebmeem kev fibrosis tshwm sim loj tsawv narrowing ntawm lub ntsws teb. Kuj tseem tshuav lawv txoj kev ncaj ncees. Cov kev hloov hauv cov kab mob tuberculosis yog nyob rau sab saud ntawm lub ntsws. Tab sis fibrosis diffuse tus cwj pwm yog ntau pronounced nyob rau hauv lub qis ib feem. Cov kabmob kheesxaws muaj nyob rau hauv nruab nrab ntawm lub ntsws, thiab nyob rau hauv carcinomatosis muaj ntau cov ntshav. Nrog tuberculosis foci muaj ntau qhov sib txawv, lawv cov localization yog subpleural. Hauv cov teeb meem ntawm pneumoconiosis, txoj kev ua rau cov qog nqaij hlav qis qis qis qis, tom qab ntawd cov paj noob hnoos, ces cov ntaub so ntswg yog sclerosed. Cov txheej txheem ntxiv ntawm kev tshaj tawm yog ntau dua tuaj kuaj mob, yog li ntawd yuav tsum muaj kev sib tw kuaj ntxiv.
