Mawu akuti "mafuta necrosis" amatanthauza focal necrosis ya adipose minofu chifukwa cha zochita za zinthu zosiyanasiyana. Mafuta a necrosis amapezeka mu kapamba, mu minofu ya retroperitoneal adipose, pakati pa mafuta a omentum, mesentery, mu minofu ya mediastinum, mu epicardial mafuta, mu mafuta osanjikiza pansi pa parietal pleura, mu minofu ya subcutaneous mafuta. m'mafupa.
Mapangidwe a anatomical a pendants mu sigmoid colon akuwonetsa volvulus ndi kukula kwa kutupa ndi necrosis. Chifukwa cha kuyimitsidwa volvulus kungakhale soldering iwo kwa parietal peritoneum kapena ziwalo zina. Mayeso ambiri a okalamba omwe ali ndi vuto la kudzimbidwa apangitsa kuti matumbo awo a sigmoid achuluke ndipo chifukwa chake zopendekera zamafuta zimakanikizidwa kukhoma lakumbuyo lamimba.
Minofu yam'mimba yam'mimba, chifukwa cha kusintha kwa hypotrophic, imakhala ndi zotupa m'malo omwe ali pachiwopsezo kwambiri, kuyimitsidwa kwamafuta am'mphepete mwa sigmoid colon kugwera mukukhumudwa kapena fossa ya parietal peritoneum, imayaka ndikugulitsidwa. Pambuyo pake, necrosis imatha kukula.
Pali mitundu ingapo ya mafuta necrosis
· Enzymatic mafuta necrosis Ndi chifukwa cha kapamba wowopsa komanso kuwonongeka kwa kapamba, kumapangidwa pamene ma enzymes a pancreatic amatuluka m'matumbo kupita kuzinthu zozungulira. Pancreatic lipase imaphwanya triglycerides m'maselo amafuta kukhala glycerol ndi mafuta acids, omwe amalumikizana ndi ayoni a plasma calcium kupanga sopo wa calcium. Zolemba zoyera, zowundana ndi tinthu tating'onoting'ono timawoneka mu minofu ya adipose. Ngati lipase ilowa m'magazi, ndiye kuti mafuta a necrosis amatha kupezeka m'malo ambiri a thupi.
· Non-enzymatic mafuta necrosis opezeka mu mammary gland, subcutaneous adipose minofu ndi pamimba pamimba, amatchedwa traumatic fat necrosis. Zimayambitsa kuchuluka kwa macrophages okhala ndi foamy cytoplasm, neutrophils ndi lymphocytes. The ndondomeko mapangidwe connective minofu (fibrosis) akhoza kuchitika, nthawi zambiri molakwika mapangidwe chotupa.
Amadziwika kuti mafuta necrosis sasintha kukhala chotupa choyipa, koma amatha kutengera. Mafuta a necrosis a mammary gland amapezeka chifukwa cha kuvulala, chifukwa chake ziwiya zazing'ono zimawonongeka, magazi amatayika. Matendawa amatha kuchitika panthawi ya chithandizo cha radiation, ndikuwonda mwachangu.
Matendawa amatha kupitilira mosavutikira kapena kumva kuwawa pa palpation. Amadziwika ndi kuwonjezeka kwa ma lymph nodes ndi mapangidwe a dimples pakhungu. Chithandizo chimaphatikizapo kuchotsa cholinga cha mafuta necrosis ndi resection.
Matenda otupa kapena necrosis wa subcutaneous adipose minofu kumachitika makamaka akhanda.
Mpaka pano, zifukwa sizinafotokozedwe. Kutanthauzira kwakukulu kwa matendawa kumawonedwa pamatako, ntchafu, kumbuyo, mikono yakumtunda ndi nkhope. Mapangidwe a njirayi amatsogoleredwa ndi kutupa kwa khungu. Necrosis mu nkhani iyi akhoza kukhala lolunjika kapena ponse. Zimatsimikiziridwa ndi kukhalapo kwa mfundo zowawa za khungu kapena zofiira ndi utoto wofiirira ndi mawonekedwe osakhazikika.
Pamalo a zotupa, kutengeka kosasinthika kwa zochitika za pathological kumatha kuchitika, komwe sikunakhaleko. Ngati mchere wa calcium umapangidwa m'dera lomwe limakhudzidwa ndi necrosis, ndiye kuti madzi amadzimadzi amatuluka, ndiyeno zipsera zazing'ono zimatha kupanga. Nthawi zina, zizindikiro zotsatirazi ndizotheka: kuchepetsa kuthamanga kwa magazi, kutopa, kusanza ndi kutentha thupi.
Kusanthula kumawonetsa kuchuluka kwa calcium m'madzi a m'magazi komanso kuchuluka kwa lipids modabwitsa. Mafuta necrosis ana akufotokozera chifukwa cha kubadwa zoopsa, asphyxia, chikoka cha otsika kutentha kapena kuchepa pachimake kutentha kwa thupi. Mu phunziroli, kusintha kwa histological ndikofunikira kwambiri, komwe kumawonetsedwa ndi makulidwe a fibrous septa, kuyika kwa makhiristo mkati mwa maselo amafuta ndi kulowa kwa cell ya granulomatous.
Matendawa amangochitika zokha, kotero chithandizo sichifunikira, sikoyenera kulakalaka ndi singano kuchokera kuzinthu zosinthasintha zapakhungu, izi zingayambitse matenda, ndiyeno zovuta zosayembekezereka zimatheka. Palinso kufalitsidwa adipose minofu necrosis, kumene adipose minofu kuzungulira mfundo zimakhala necrotic.
Pankhaniyi, kutentha kwa thupi kumakwera nthawi zonse, nyamakazi imakula, ndipo ziwalo zimawonongeka. Kufalikira kwa necrosis ya minofu ya adipose kumabweranso chifukwa chakuti ma pancreatic enzymes amalowa m'magazi kapena zamitsempha. Chiwerengero cha imfa mu mtundu uwu wa adipose minofu necrosis ndi wokwera kwambiri, muyenera kukumbukira nthawi zonse kuti muyenera kufotokozera dokotala wanu zizindikiro za thanzi labwino. Chithandizo chamankhwala chapanthawi yake chokha chimathandizira kuteteza thanzi.
