Occlusion - chii? vascular occlusion

In mushonga kana diagnosing wakaomarara chirwere rinowanzoshandiswa uye rokuti "occlusion". Chii? Imhandoi Kumwe kuchinja kunotanga vari shure kwake uye chii chikonzero tingaziva kuvapo occlusion? Izvi zvichakurukurwa munyaya yanhasi nyaya. oudzame zvikuru ari vascular occlusion, ayo zviratidzo uye nzira nekumisa kuongororwa zvakarurama.

Vachiravana, pamusoro pfungwa occlusion mu dentistry

"Occlusion" - yakakura izwi. In dentistry Somuenzaniso, rinoreva chero kuonana pakati pameno okumusoro shaya. Saka, nechepakati occlusion (nzvimbo ine kunonyanyisa nhamba mazino pakati pameno neshamwari, sezvamakaropafadzwa mutsetse unopfuura pakati okumusoro incisors rushaya rinobatana ane makore chiso notional) - iri anongoda kufanana pfungwa occlusion. Ndiko, kuruma anoonekwa imwe reshiyo mazino akatsunga centric occlusion.

In dentistry kusiyanisa marudzi occlusion zhinji. Saka, vakawanda chaizvo nyaya malocclusion, somuenzaniso, kukonzerwa underdevelopment pakati rapazasi shaya , kana, Ukuwo, kunyanya kukura kwayo - chinhu distal occlusion. Unofanira kunge wakaona nokuruma ichi: mazino mberi yokumusoro kana rinogumisa yepazasi mutsara kwemeno.

Asi isu kuchaita mberi, kuti uzive zvakaita occlusion uye zvavo mushonga.

The occlusion rwengarava ngozi

Vanachiremba, kureva occlusion mamiriro chinorehwa chero mukaha anatomical inotungamirwa: asi node kana ropa midziyo, iro subarachnoid (subarachnoid) nzvimbo, etc. - iro akavharwa somugumisiro masvingo aro lesion kana chimiro namamota, occlude ari lumen.

vascular occlusion - iri kutanga ngozi zvikuru, nekuti Somuenzaniso, nokuderedza permeability kwavo kunogumawo kukundikana zhinji nhengo dzakavandika dzevanhu. Izvi mhando zvokurwara mune zvokurapa zvakakodzera kupiwa zvikuru ngozi zvemwoyo, izvo, zvinosuruvarisa kusvikira nguva yedu pamusoro aitungamirira nzvimbo pakati utano matambudziko zverufu kana zvakakomba urema.

Chinokonzera vascular occlusion

Chokutanga, unofanira kujekesa chii chaizvo kunokonzera vascular occlusion: nayo chinokurwadzai chirwere uye zviratidzo zvayo Dzakafanana. ruzivo Izvi zvakakodzera chaizvo nokuti vakawanda nguva yakapiwa nokuda urongwa zvashata rubatsiro varwere dzakadaro, akaverenga sezvariri kwemaawa, kana kunyange maminitsi.

Zvikonzero dzinosanganisira occlusion kuparadza kuvimbika vascular masvingo, ropa coagulation, uye varicose mutsinga. abnormalities Kazhinji vakadaro riparadzirwe uye shamwaridzana nemigumisiro zvirwere kana matambudziko aro, uyewo atrial fibrillation.

Somugumisiro, kukundikana mwero dzimwe nzvimbo mwoyo wakanaka thrombi vari kuumbwa, iyo panguva unopinza kuwedzera BP, kuzvidya mwoyo kana kushandisa atrium uye vabudiswa kubva pindana midziyo dzichichera mumapapu kana maoko nemakumbo yakaderera.

Murwere anonzwa, somunhu ushe, rakapinza pakarepo sezvo ropa clot chinokutsimbirirai ngarava rusvingo marwadzo, asi raspiraya ukuwo, uye pamusoro etsinga harinzwi. Marwadzo anogona kufukidza nzvimbo dzakakura chaizvo, uye murwere dzimwe nguva kunyange kukwanisa kudoma chaipo umo vemunyika.

mhando occlusion

Yeuka kutaura zvokurwara rinonzi occlusion, riri murombo kuparadzirwa pakati localization yavo rakakamurwa ari venous uye arterial ropa, rinobaya huru midziyo kuti uvake muviri womunhu muviri, ayo nechepakati tsinga uye maoko nemakumbo. Uye zvichienderana nenguva uye hunhu chirwere - chakasimba uye chirwere siyana.

Kana Nzvimbo kunodzivisa blockage ari mudziyo pedyo ropa aibuda kutamira pamwe zvakasimba inotungamirwa, tiri kutaura pamusoro embolism. Kwahunokonzera murombo kutenderera. Uye nokudaro afunge rimwe thrombus itsva. Ichi chirwere inozivikanwa se kukurumidza kudana nokuda okukurumidzira kupindira. Zviri reversible chete mumaawa 6 wokutanga, uye ipapo kunounza tishu necrosis.

Zviratidzo chenjera embolism

Sezvo imi makaona, zvose munyama dziri mudziva ngarava, uyo akafirwa patency achiona necrosis. Nguva yokubatsira, zvakakosha kuziva zviratidzo, dzinoratidzwa nezve pathological ezvinhu:

• chenjera kwakaerekana Pazvinotanga;
• kungoerekana kurwadziwa;
• ganda pa nzvimbo blockage inova rakacheneruka uye chando kuti kubata, pane zvinoratidzwa imwe nguva gare gare ine machena muenzaniso cyanosis;
• panzvimbo is occlusion pakaitika mudziyo;
• ganda anorasikirwa utetsa kwayo;
• Akanetseka muviri mabasa sei occlusion.

Chii kunotaurwa zvinokonzera kutyora ropa mudziyo patency

Nokuti kutsunga yakarurama chikonzero, iyo anokonzerwa occlusion pakati tsinga, pane tsanangudzo dzakawanda.

• Saka, Somuenzaniso, rinonzi embolism blockage zvaakatadzisa richipfuura ngarava thrombus (ropa clot),. Uye kazhinji nenguva moyo Fani iyi nhema mwoyo chirwere. Vanovata ropa clots ari in nomwoyo.
• A thrombosis - a blockage, ropa clot, yakabuda pamasvingo midziyo ropa somugumisiro kuzara.
• Obliteration - a lumen kuvhara atherosclerotic Dombo iri atherosclerosis kana aienda Kuchinja ayo somugumisiro ngarava pamadziro, iyo inomuka kana vatsvaire endarteritis.
• Aneurysm - zvinoshamisa kuwedzera kana bulging ngarava pamadziro, unowanikwa semubairo thrombosis, uye kazhinji entailing embolism.

Lower richiripo midziyo

repasi muzvidimbu occlusion pakati kodzero kuiswa ari oga chikamu, sezvo zvokurapa nhamba chinyorwa kuti hafu yose anozivikanwa zviitiko blockage rikaitika femoral kana popliteal tsinga. zvokurwara rino rakakamurwa chakasimba uye chisingaperi.

Zviratidzo chenjera siyana akadzidza zvakadzama uye vakarondedzera uye kuderedzwa kuna shanu mukuru features, vanoratidza mumwechete izvo zvinoda nechimbichimbi chirwere uye kurapwa. Vose vari kunyorwa chikamu zviratidzo rikwanise embolism. Late chirwere uye kutora matanho kungaita kuti kusingarapiki kuchinja munyama uye kurasikirwa maoko nemakumbo.

Kuonekwa ichi chakakomba zvokurwara surgically. Pakutanga mishonga chirwere ndehwokuti kudzorera kuparadzirwa uye neronda rinonyenga ari kukura ezvinhu zvinoda richiripo kudimurwa.

Chirwere occlusion - chii?

Kana ari chirwere chimiro chirwere, varwere pakutanga chokunyunyuta pamusoro kuneta kunouya nokukurumidza kana achifamba, kurwadziwa, iri mhuru tsandanyama, kunzwa nemakumbo nechando, uyewo atindivare ganda pamusoro pavo.

In mamwe maitiro chepfungwa chirwere anova inoratidza claudication. Zvinonzi anokonzerwa kurwadziwa kuti kumbowanikwa remhuru anoita mira. Murwere achimirira wake kuregererwa uye vanogona kuenda zvakare. Persistent marwadzo, nenzira, chiratidzo kana nouchapupu mberi occlusion nhengo dzake.

Murwere kuongororwa inoratidza kuchinja zvinyama: ganda atrophied, rakachenuruka, muviri bvudzi rake ndisipo, zvipikiri thickened uye chiwondomoke. Necrotic kuchinja kuitika pakutanga mottled rinokwanisa kucheneruka, kunyanya inotsika nezvigunwe. Ndakabatana Zvirwere kazhinji rinobatanidza neronda rinonyenga. In kwokutanga nzendo zvokurwara kubatwa conservatively muchipatara uye nechinangwa kudzorera ropa kuyerera uye mukuvandudza metabolic kwendangariro.
