Izwi rokuti "fat necrosis" rinoreva focal necrosis yeadipose tissue nekuda kwekuita kwezvinhu zvakasiyana-siyana. Fat necrosis inoitika mupancreas, mune retroperitoneal adipose tishu, pakati pemafuta eomentum, mesentery, mumafuta emukati memediastinum, mumafuta epicardial, mumafuta akadzika pasi peparietal pleura, mune subcutaneous mafuta tishu uye mumwongo.
Iyo anatomical chimiro chependants mu sigmoid colon inoratidza volvulus yavo uye kukura kwekuzvimba uye necrosis. Chikonzero chekumisa volvulus chinogona kunge chiri kuvatengesa kune parietal peritoneum kana dzimwe nhengo. Kuongororwa kwakawanda kwevakweguru vanorwara nekuzvimbirwa kwakatungamira kumhedzisiro yekuti sigmoid colon yavo yakawedzera saizi uye nekudaro mafuta pendants anotsikirirwa kumadziro anterior abdominal.
Iyo mhasuru dzeanterior abdominal wall, nekuda kwekushanduka kwe hypotrophic, ine hernias munzvimbo dzinonyanya kutambudzika, mafuta ekumisikidza emahara emupendero we sigmoid colon anowira mukuora mwoyo kana fossa yeparietal peritoneum, inozvimba uye inotengeswa kwairi. Zvadaro, necrosis inogona kukura.
Kune marudzi akawanda emafuta necrosis
· Enzymatic mafuta necrosis mhedzisiro yeacute pancreatitis uye kukuvadzwa kwepancreas, inoumbwa apo pancreatic enzymes inobuda mumaduta mumatishu akatenderedza. Pancreatic lipase inotyora triglycerides mumasero emafuta kuita glycerol uye fatty acids, iyo inozobatana neplasma calcium ions kuita sipo yecalcium. Machena, matete plaques uye nodules anoonekwa mune adipose tissue. Kana lipase ichipinda muropa, ipapo mafuta necrosis anogona kuonekwa munzvimbo dzakawanda dzemuviri.
· Non-enzymatic mafuta necrosis akaonekwa muzamu rezamu, subcutaneous adipose tissue uye mudumbu remukati, inonzi traumatic fat necrosis. Inokonzera kuwedzera kwenhamba ye macrophages ane foamy cytoplasm, neutrophils uye lymphocytes. Iyo nzira yekuumbwa kwekubatanidza tishu (fibrosis) inogona kuitika, kazhinji kukanganisa kuumbwa kwebundu.
Zvinozivikanwa kuti mafuta necrosis haashanduke kuita bundu rakashata, asi anogona kuitevedzera. Fatty necrosis yemammary gland inoitika semugumisiro wekushungurudzika, semugumisiro wemidziyo miduku yakakuvadzwa, ropa rinopera. Iyi pathology inogona kuitika panguva yeradiation kurapwa, nekukurumidza kuonda.
Chirwere ichi chinogona kuenderera chisingarwadze kana nekunzwa kurwadziwa palpation. Iyo inoratidzirwa nekuwedzera kwe lymph nodes uye kuumbwa kwemadimples paganda. Kurapa kunosanganisira kubvisa kutariswa kwemafuta necrosis nesectional resection.
Chirwere chinoputika kana necrosis ye subcutaneous adipose tissue inowanzoitika muvana vachangoberekwa.
Kusvika iye zvino, zvikonzero hazvina kujekeswa. Iyo huru yenzvimbo yeiyo pathology inoonekwa pamagaro, zvidya, kumashure, maoko epamusoro uye kumeso. Kuumbwa kwechiitiko ichi kunotungamirirwa nekuputika kwakaoma kweganda. Necrosis munyaya iyi inogona kutarisa kana kupararira. Inotaridzirwa nekuvapo kwenode dzinorwadza dzeganda reganda kana tsvuku nepepuru tint uye chimiro chisina kujairika.
Panzvimbo dzemaronda, kungoita neutralization kwepathological phenomena kunogona kuitika, kubva izvo pasina zvisaririra zvinosara. Kana calcium salt yakaumbwa munzvimbo inobatwa necrosis, ipapo mvura yemvura inobuda, uye ipapo mavanga maduku anogona kuumba. Muzviitiko zvisingawanzoitiki, zviratidzo zvinotevera zvinogoneka: kuderedza ropa, kupera simba, kurutsa uye feverish mamiriro.
Ongororo inotaura kuwedzera kwehuwandu hwe calcium mu plasma yeropa uye yakakwira zvisina kujairika mwero we lipids. Fat necrosis muvana inokura semugumisiro wekushungurudzika kwekuberekwa, asphyxia, simba rekushisa kwakadzika kana kuderera kwekushisa kwemuviri wepakati. Muchidzidzo, shanduko yehistological yakakosha zvikuru, inoratidzwa nekukora kwefibrous septa, kuiswa kwemakristasi mukati memasero emafuta uye granulomatous cell inopinda.
Chirwere ichi chinongoerekana chavapo, saka kurapwa hakudiwi, hazvikurudzirwe kushuvira netsono kubva kuchinjika zvinhu zveganda, izvi zvinogona kukonzera hutachiona, uye ipapo matambudziko asingatarisirwe anogoneka. Kune zvakare yakaparadzirwa adipose tishu necrosis, apo adipose tishu kumativi majoini anova necrotic.
Muchiitiko ichi, kutonhora kwemuviri kunogara kuchikwira, arthritis inokura, uye majoini anoparadzwa. Yakaparadzirwa necrosis yeadipose tishu inomukawo kubva pakuti pancreatic enzymes inopinda muropa kana lymph. Nhamba yekufa mumhando iyi yeadipose tissue necrosis yakakwirira kwazvo, unofanira kugara uchiyeuka kuti unofanira kuudza chiremba wako chero zviratidzo zvehutano husina kunaka. Kutarisirwa kwekurapa panguva yakakodzera chete kunobatsira pakuchengetedza hutano.
