Occlusion - ntoni na? occlusion olujikeleza

Xa amayeza xa zokufumanis isifo kakhulu wayedla kwaye igama elithi "occlusion". Yintoni na? Luhlobo olunjani utshintsho zophendlo lwezifo na ngasemva kwakhe yaye ngasiphi isizathu sikwazi phambi occlusion? Oku kuza kuxoxwa ngazo kwinqaku yanamhlanje. ngokweenkcukacha ezininzi occlusion semithambo, iimpawu zayo nendlela sentlalo ukuxilongwa.

Ngokwahlukeneyo, malunga ingqiqo occlusion in wamazinyo

"Occlusion" - igama ebanzi. Xa bamazinyo, umzekelo, oko kuthetha nayiphi zoqhagamshelwano amazinyo kwemihlathi eliphezulu nengasezantsi. Ngenxa yoko, occlusion engundoqo (indawo kunye nani liphezulu amazinyo phakathi abafowunelwa kwamazinyo, apho umgca abadlula phakathi siphume ephezulu nesezantsi umhlathi ingqamana a eziqingqiweyo yee-zobuso) - phantse iyafana ingqikelelo occlusion. Oko kukuthi, inyeke uthathwa umlinganiselo othile amazinyo kumiselwa occlusion phambili.

Xa kwezamazinyo ukwahlula iintlobo ezininzi occlusion. Ngoko ke, kukho iimeko aqhelekileyo kakhulu malocclusion, umzekelo, kubangelwa wokungaphuhliswa emhlathini esezantsi , okanye, icala, uphuhliso yayo ngokugqithiseleyo - yinto occlusion distal. Wena mhlawumbi wayibona le esinayo silume umntu: ngamazinyo phambili xa ivale umqolo esezantsi kwamazinyo.

Kodwa siza kuhambela phambili, ukufumanisa ukuba yintoni na occlusion kwaye amayeza ngokubanzi.

Le occlusion eyingozi kweenqanawa

Amagqirha, ibhekisela imeko occlusion ukuthini na kumiswa umngxuma yokwakheka: i nkovu okanye imithambo yegazi, i subarachnoid (subarachnoid) isithuba, njl - nto leyo ivaliwe ngenxa yeendonga sisilonda esidumbileyoesingaphakathi yayo okanye imbonakalo yamathumba, occlude le mithambo.

occlusion semithambo - oku yinkolelo luyingozi kakhulu, ngenxa yokuba, umzekelo, ukunciphisa permeability yabo kungabangela ukungaphumeleli amalungu ezininzi zabantu. Olu hlobo leengxaki amayeza eyayifanele yenziwe izifo eziyingozi kakhulu sentliziyo, leyo, ngelishwa, ngexesha lethu phezu kwendawo akhokelayo phakathi iingxaki zempilo ezikhokelela ekufeni okanye ukukhubazeka kakhulu.

Unobangela of occlusion yegazi

Okokuqala, kufuneka icacise oko kanye ebangela occlusion nemithambo: oko kuphakamisa sifo kunye neempawu zayo ezikhangeleka. Le nkcazelo kuyimfuneko kakhulu kuba uninzi ixesha elabelwe yokubonelela uncedo olungxamisekileyo kwizigulane ezinjalo, ibalwe linjalo iiyure, okanye imizuzu.

Izizathu ziquka occlusion wayonakalisayo ukuthembeka beendonga semithambo, coagulation igazi, ngemithambo varicose. ukungaqheleki amaninzi enjalo kwegazi kunye tsalelani neziphumo nezifo ezosulelayo okanye iingxaki zawo, kwakunye ne fibrillation atrial.

Ngenxa yoko, izinga ukungaphumeleli kwiindawo ezithile intliziyo thrombi entle bayazibhijabhija, ngelo xesha nje ukunyuka okukhulu uxinzelelo lwegazi, uxinezeleko okanye asebenzise intendelezo betekisi ukusuka iimpahla sifana ukondla imiphunga okanye asezantsi imilenze.

Isigulane kunjani, njengokuba umthetho, okubuhlungu yequbuliso njengoko ihlwili legazi ngokucinezela phezu kodonga inqanawa, kodwa raspiraya, ngokulandelelanayo, yaye phezu kwalapho. Iintlungu kungabonakali kakhulu indawo enkulu, kwaye isigulane akubi nokuba nako ukuchana apho yenzelwe.

iintlobo occlusion

Khumbula ukuba ukhankanye ngezifo ekuthiwa occlusion, nto leyo kwegazi zalapha ekhaya wabo yahlulwe lwemithambo kunye lwemithambo yegazi, echaphazela iimpahla eziphambili ukuba sikhule umzimba womntu, inkqubo yayo luvo omzimba. Kwaye kuxhomekeke kwixesha kunye nohlobo izifo - iifomu oyingozi futhi ezigulo ezondeleyo.

Xa elimi luthintela ukuvaleka inqanawa eyenziwe ukuhamba kwegazi ihamba kunye ukuma tight, sithetha Embolism. Oku kubangela kwegazi. Ngaloo ndlela, Nokumphikisa a thrombus entsha. Le meko luphawulwa ngobizo engxamisekileyo yokungenelela ingxamisekile njengokuba ixesha. Kuyinto ingathityazwa kuphela kuqala kwiiyure ezi-6, uze emva koko kukhokelela kwezihlunu necrosis.

Iimpawu Embolism ahlekise

Njengoko sele sibonile, zonke izicwili ukuba echibini wesitya, abaphulukana patency baye necrosis. Ukuze ube nexesha ukunceda, kubalulekile ukwazi iimpawu, luphawulwa inkangeleko imeko zophendlo lwezifo:

• abaqala ngequbuliso olunamandla;
• ubuhlungu obukhulu ngequbuliso;
• isikhumba kwindawo le ukuvaleka kuba luthuthu nengqele ukuya ngaphandle kwebala, akukho iboniswa ixesha elithile kamva kunye cyanosis ipateni nezemarmore,
• endaweni isitya ukuphazamiseka kweintanethi occlusion;
• isikhumba ulahlekelwa uvakalelo sayo;
• imisebenzi umzimba zaphazanyiswa ochaphazelekayo occlusion.

Yintoni ekuthethwa oonobangela igazi ukungathobeli isitya patency

Kuba nokuzimisela echanekileyo isizathu, apho kwaye kwenziwa occlusion kwemithambo, kukho iingcaciso eziliqela.

• Ngoko ke, umzekelo, ekuthiwa Embolism ukuvaleka, nto leyo lihambe thrombus inqanawa (ihlwili legazi). Yaye ngokufuthi xa intliziyo kwalo mmangaliso kulala nesifo sentliziyo. Balala egazi igazi nemingxuma yentliziyo.
• A thrombosis - ukuvaleka, ihlwili legazi, owayebonakele iindonga imithambo yegazi ngenxa ingxinano.
• Obliteration - Ukuvalwa mithambo nebhodi atherosclerotic kwi yamafutha okanye licuthe utshintsho zalo ngenxa emithanjeni, nto leyo kuvela xa lokutshabalalisa endarteritis.
• Kwemithambo - yokwanda kakhulu okanye equmbile beendonga isitya, ebonakala ngenxa thrombosis, kunye Embolism ngokufuthi esizakukhokelela.

imikhumbi Lower kwemilenze

omzimba occlusion esezantsi ekunene ukuba bafakwe kwindawo eyahlukileyo, njengoko amanani zonyango ingxelo ukuba isiqingatha zonke iimeko ezaziwayo ukuvaleka lwenzeka kwi kwemithambo femoral okanye popliteal. Le ngezifo yohlulwe acute kunye ezigulo ezondeleyo.

Iimpawu iifom etsolo kufundwe iinkcukacha ezichazwe kwaye azezi iinkalo ezintlanu eziphambili, ukubonisa ubuncinane enye yazo kufuneka kwesifo olungxamisekileyo unyango. Bonke bephela zidweliswe kwicandelo iimpawu Embolism ahlekise. sifo emva kwexesha kwaye amanyathelo ukuthatha kusenokukhokelela kwiinguqu vuhlayiseki emzimbeni kunye nelahleko omzimba.

Ezinyangiweyo le ngezifo kakhulu intsumpa. Ekuqaleni nothomalaliso sifo ujolise ukubuyisela kwegazi ukubola kwiimeko zophuhliso zifuna lomzimba okwalandelwa.

occlusion Chronic - ntoni na?

Kwimeko kwefom ezingapheliyo zesi sifo, izigulane ekuqaleni ezikhala ukudinwa iza ngokukhawuleza xa ehamba, iintlungu, ukubonakala kwi izihlunu ithole, eziva amalungu ukuqanda, kwakunye kombala ulusu phezu kwabo.

Xa uphawu olunye uphawu esi sifo iba claudication uveza. Oku kubangelwa ntlungu yenzeka lamathole kwenza ayeke. Isigulane ulinda uxolelo wakhe ungaya kwakhona. intlungu engapheliyo, ngasendleleni, uphawu okanye occlusion enkulu phambili amalungu omzimba.

uviwo isigulane ibonisa utshintsho esiqwini: eluswini atrophied, libunile, iinwele zakhe umzimba ndingekho, iinzipho anquma kwaye ukuwa. utshintsho Necrotic zenzeka ekuqaleni obuxutywe oluhlaza, ingakumbi ngeentende neenzwane. Kunye izifo ngokuqhelekileyo ibandakanya ukubola. Kumanqanaba okuqala e-leengxaki baphathwa ngokulumka esibhedlele yaye lujoliswe ukubuyisela ukuhamba kwegazi kunye nokuphucula iinkqubo metabolic.
