Occlusion - kuyini? occlusion semithambo

Kwezokwelapha lapho ekuhlonzweni kwezifo okunzima wayevame ukusebenzisa futhi igama elithi "occlusion". Kuyini lokhu? Hlobo luni izinguquko sokugembula kukhona ngemva kwakhe, ngasiphi isizathu singakwazi ukuthola khona occlusion? Lokhu kuzoxoxwa ngakho esihlokweni lanamuhla. ngokuningiliziwe occlusion semithambo, izimpawu zayo kanye esebenzisa ebeka ukusazi ngokunembile isifo esikuphethe.

Endaweni ehlukile, cishe nomqondo occlusion amazinyo

"Occlusion" - a term ebanzi. Amazinyo, isibonelo, isho noma yiluphi ulwazi contact ngamazinyo emhlathini yasenhla nemithombo yasenzansi. Ngakho, occlusion central (indawo nenani eliningi amazinyo phakathi oxhumana amazinyo, lapho umugqa odlula phakathi amazinyo yasenhla nemithombo yasenzansi emhlathini kuvumelana a esinikelweko maphakathi no-ebusweni) - cishe iyafana nomqondo occlusion. Okusho ukuthi, lapho olunywe kubhekwa isilinganiso esithile amazinyo ezinqunywe occlusion centric.

Amazinyo ukuhlukanisa izinhlobo eziningi occlusion. Ngakho, amacala ejwayeleke kakhulu malocclusion, isibonelo, senziwa nokungathuthuki ka umhlathi ongezansi , noma, Ngakolunye uhlangothi, ukuthuthukiswa kwalo ngokweqile - kuyinto occlusion distal. Mhlawumbe usuke wazibona le bite: engenhla phambi amazinyo uma evala irowu engezansi amazinyo.

Kodwa ingabe thina ukuhamba, ukuthola lokho occlusion futhi imithi jikelele.

I esiyingozi occlusion imithambo

Physicians, ebhekisela isimo occlusion ehloselwe yimuphi kumiswa eziyize yokwakheka: ama-lymph noma igazi izitsha, le subarachnoid (subarachnoid) isikhala, njll - okuyinto ivaliwe ngenxa izindonga zawo lesion noma ukubukeka izimila, occlude mafutha anciphisa isikhala esingaphakathi.

occlusion semithambo - lokhu iyisici kuyingozi kakhulu, ngoba, isibonelo, ekunciphiseni permeability kwazo kungaholela ukwehluleka kwezitho zomzimba eziningi. Lolu hlobo lwe-pathology kwezokwelapha iyiswe izifo eziyingozi kakhulu senhliziyo nemithambo yegazi,, ngeshwa, kuze kube sesikhathini sethu, endaweni aholayo phakathi zezinkinga zempilo ekufeni noma ukukhubazeka ezinzima.

Imbangela occlusion semithambo

Okokuqala, udinga ukucacisa lokho ncamashi kubangela occlusion semithambo:-ke kuphakamisa isifo futhi izimpawu zaso ibukeke. Lolu lwazi kudingeka kakhulu ngoba iningi isikhathi esabelwe nokuhlinzekwa kosizo oluphuthumayo iziguli ezinjalo, kubalwa ngokoqobo amahora noma ngisho imizuzu.

Izizathu zihlanganisa occlusion kokubhubhisa ubuqotho izindonga imithambo yegazi, igazi coagulation, futhi varicose emithanjeni. kwezinso Ngokuvamile anjalo esikhathini kwegazi futhi uzihlanganise imiphumela yezifo ezithathelwanayo noma yezinkinga zayo, kanye fibrillation atrial.

Ngenxa yalokho, inani eliphindwe ukwehluleka ezindaweni ezithile inhliziyo thrombi esihle akhiwa, okuyinto ngesikhathi ukwanda elibukhali blood pressure, ukucindezeleka noma asebenzise ATRIUM futhi ukhiphe izitsha ezedlulayo ukusuthisa amaphaphu noma nemilenze aphansi.

Isiguli azizwa, njengoba umthetho, ehlome ubuhlungu okungazelelwe njengoba ihlule legazi ngokucindezela phezu odongeni isitsha, kodwa raspiraya, ngokulandelana, futhi phezu eziyimpumelelo emsipheni. Ubuhlungu uzisibekele ngempela endaweni enkulu, kanti isiguli kwesinye isikhathi ngisho ukwazi ukusho ukuthi lapho itholakala.

izinhlobo occlusion

Khumbula ingasaphathwa zokugula ngokuthi occlusion, okuyinto kahle kwegazi e kwasendaweni yabo luhlukaniswe pooling eyeqile lwemithambo yegazi, ezithinta izitsha main ukuthi ukuncelisa emzimbeni womuntu, uhlelo lwayo sezinzwa nasemilenzeni. Futhi kuye ngokuthi yisiphi isikhathi kanye nohlobo isifo - amafomu oyingozi futhi ezingalapheki.

Lapho isimo sezwe kuvimbela ukuvaleka isitsha ngumuntu ukugeleza kwegazi ezihambayo kanye ukwakheka tight, sikhuluma embolism. Kubangela kwegazi ompofu. Futhi kanjalo ingqondo a thrombus entsha. Lesi simo esibonakala njengoba ngobizo esiphuthumayo kokungenela esiphuthumayo. Kuba esethola kuphela amahora okuqala angu-6, bese kuholela izicubu necrosis.

Izimpawu embolism acute

Njengoba usulibonile, zonke izicubu ezisesandleni pool bomkhumbi, owashonelwa patency ibhekane necrosis. Ukuze isikhathi ukusiza, kubalulekile ukwazi izimpawu, libhekene ukubukeka isimo sokugembula:

• acute kuqala okungazelelwe;
• okungazelelwe sebuhlungwini obunzima;
• isikhumba endaweni le ukuvaleka iba eliphaphathekile futhi abandayo touch, lapho kuboniswa kwesikhathi esithile nge cyanosis zemabula iphethini;
• endaweni occlusion okungaxhunyiwe ku-intanethi yokwanda isitsha;
• isikhumba ilahlekelwa ukuzwela yayo;
• siyabhubha umzimba imisebenzi abathintekayo occlusion.

Yini ubizwa izimbangela ukwephulwa igazi isitsha patency

Ukuze isinqumo olunembile imbangela, okwakubekelwa okubangelwa occlusion we Umthambo, kukhona izincazelo eziningi.

• Ngakho, ngokwesibonelo, ngokuthi embolism ukuvaleka, okwakwenza lihambe thrombus isitsha (igazi ihlule). Futhi ngokuvamile at inhliziyo lesi simanga amanga isifo senhliziyo. Tibangela amahlule e izimbotshana zenhliziyo.
• A thrombosis - a ukuvaleka, igazi ihlule, eyabonakala on the Imithambo yegazi ngenxa ukucinana.
• Nokwaphakade - a inesikhala Ukuvalwa qwembe atherosclerotic e isifo sokuqina kwemithambo yegazi noma ukuvaleka izinguquko zalo ngenxa izindonga isitsha, okuyinto kuphakama lapho nya endarteritis.
• Useshonile - kamanye noma ezinkulu izindonga isitsha, okubonakala ngenxa thrombosis, futhi ngokuvamile entailing embolism.

izitsha esitho Lower

aphansi esitho occlusion ilungelo ibekwe esigabeni ahlukene, njengoba izibalo yezokwelapha irekhodi ukuthi ingxenye yawo wonke amacala eyaziwayo ukuvaleka kwenzeka Umthambo femoral noma popliteal. Lokhu zokugula sehlukaniswe oyingozi futhi ezingalapheki.

Izimpawu amafomu acute wafunda ngokuningiliziwe futhi kuchazwe futhi yehlise izici ezinhlanu eziyinhloko, ukubonisa okungenani eyodwa edinga uphethwe eziphuthumayo kanye nokwelashwa. Bonke ahlelwe esigabeni izimpawu of embolism oyingozi. ukuxilongwa sekwephuzile futhi isenzo ukuthatha kungaholela izinguquko ezingenakuhlehliswa kwezicubu kanye nokulahlekelwa nasemilenzeni.

Waphatha lokhu zokugula ezinzima surgically. Ekuqaleni yokwelapha isifo ihlose ukubuyisela kwegazi nezilonda ezingapholi ezimweni ukuthuthukiswa zidinga esitho ukunqunywa.

occlusion Okungalapheki - kuyini?

Endabeni ifomu njalo lesi sifo, iziguli ekuqaleni esekhala ukukhathala iza ngokushesha uma uhamba, ubuhlungu, elivela imisipha ithole, uzizwa nemilenze okokuqandisa, kanye ichaza ukushintsha kombala isikhumba kubo.

Eqhubeka sici isici isifo siba claudication ngakanye. Sibangelwa ubuhlungu ezenzeka amathole futhi kwenza ayeke. Isiguli ulindela ukuthethelelwa wakhe futhi ungaya futhi. ubuhlungu ophikelelayo, ngasendleleni, isibonakaliso noma occlusion eningi okuqhubekayo nasemilenzeni.

luhlolo nesineke ikhombisa ushintsho izicubu: isikhumba atrophied, ugodo, iziboya emzimbeni wakhe engekho, izinzipho uqweqwe futhi sidilike. izinguquko Necrotic zenzeka ekuqaleni mottled bluish, ikakhulukazi amathe namazwani. Ukujoyina izifo ngokuvamile akuhileli esibhibhayo. Ezigabeni zokuqala zokugula iphathwa conservatively esibhedlela futhi kuhloswe ekubuyiseleni ukugeleza kwegazi futhi sithuthukisa izinqubo umzimba.
