Pamusana pezvinhu zvakasiyana-siyana zvehutachiona, kunze kana mukati, mishonga inorarama yemuviri inogona kugadziriswa uye isfa. Hazvizokwanisi kudzorera masero akafa, asi zvinogona kumira izvi, zvichidzivirira kuparadzirwa kwayo. Kurapa kwakakodzera kunokosha kuziva marudzi ose einecrosis, sezvo kunyatsosiyanisa kugadziriswa kunobvumira kukanganisa chikonzero chekutanga chemuviri wekufa, uye kwete migumisiro yaro.
Mhando dzakakura dze necrosis uye zvinokonzera kuonekwa kwayo
Muchirapa, ndeye tsika yekuisa necrosis yemasero maererano nemitemo 3.
Saizvozvowo, maitiro anotevera echirwere anozivikanwa:
- trophononeurotic;
- ischemic;
- allergic;
- dambudziko;
- toxigenic.
Iyo nzira yekusimudzira inoparadzanisa necrosis yakananga, iyo inosanganisira mbiri dzekupedzisira dzezvirwere kubva pane zvakarongwa pamusoro apa, uye rudzi rwakasiyana rwehutachiona, runosanganisira mamwe marudzi ose.
Pano panewo maitiro zvichienderana nekliniki zviratidzo zvechirwere uye marphological maitiro ake:
- Caseous;
- heart attack;
- inobatanidza kana yakaoma;
- fibrinoid;
- gangrene;
- waxy;
- zvinodzvinyirira;
- zvakakanganiswa kana mvura;
- sequestration;
- fatty.
Nzira yakanyanya kunyanya ye necrosis is isicic (vascular) rufu rwezvinyama zvemwoyo - chirwere chemwoyo . Mafomu akasara anowanikwa munenge chiyero chakafanana.
Mugumisiro wemhando mikuru ye necrosis pamatanho akasiyana
Pane zvakawanda zvakaguma migumisiro yezviri kuitwa pasi pekufungisisa. Pakati pavo, pane 7 zvakasiyana-siyana zvechirwere chekurwara, apo chirevo chacho chekutanga chinotarisirwa:
- Kuongororwa - kune kupatsana kwemasero akafa, uye kune avo vakavhiringidzika pakuputika. Izvi zvinovimbisa kupatsanurwa kwehutano hwakanaka uye hutachiona. Munharaunda yakakanganiswa kune edema uye kubwinya, kuwedzerwa kwekupararira kweropa, iyo inobvumira leukocyte uye phagocytes kuti izvimirire kubvisa masero akaora.
- Sangano - kushandiswa kwezvisikwa zvakasviba nehuru. Mushure mokunge kubviswa kwe-necrosis panzvimbo yaro pane hoora.
- Incapsulation - nzvimbo ine masero akafa inongogumira kune capsule yezvibatanidza.
- Kuchengetedza kana kupfurikidza ndiko kuoma kunowanikwa kwezvenjeti nemhaka yekuunganidza kalmanium munyu (dystrophic calcification).
- Ossification isarudzo isingawanzoitiki yekuenderera mberi kuverenga, apo mapfupa emapfupa anowanikwa panzvimbo yeNecrosis.
- Kistoobrazovanie - mugumisiro wechirangariro chechirwere ichi.
- Kusvibiswa ndiyo iyo yakaipa zvikuru yemigumisiro yechirwere. Nzvimbo ine mavara ane tsvina anonyunguduka pasi pechiito che purulent zvirongwa uye pathogenic mabhakitiriya .
