Stenting imithambo wenhliziyo

Ukuze ekwelapheni isifo senhliziyo, ogxile ukuvaleka kwemithambo yegazi yenhliziyo (zidla myocardium), ngo-1977 ibhaluni angioplasty lezi zitsha wawenziwa okokuqala. Ezimweni eziningi, imbangela ukuvaleka kwemithambo kukhona imali fat phezu intima imithambo, okuholela benezincwadi enganele oxygen cardiomyocytes. Ngenxa yalokho, angina asathuthuka futhi isilethikusebenza.

Ibhaluni angioplasty amasu kusekelwe iqiniso lokuthi inhliziyo ngokusebenzisa le femoral Umthambo ipayipi zazidla abakuphela itholakala cuff (ibhaluni deflated). Ngaphansi-X-ray ukulawula ipayipi sidla ngokuqondile kwisayithi ye ukuvaleka, bese ibhaluni is Ayihaba - umfula unwetshiwe. Indlela linikeza imiphumela emihle, kodwa ngokuvamile lokubuya kwesifo (Umthambo kabusha uncipha futhi kakhulu).

Ukuze wandise ukusebenza kwe ibhaluni angioplasty, odokotela baye basungula indlela entsha - inhliziyo stenting semithambo. A stent kuyinto metallic ijabulise anezikhala, uhlobo engagqwali uzimele. Ngaphakathi Umthambo, ke yandisa, hhayi sivumele yona spasm. Inhliziyo stenting semithambo wenziwa ngezinto ezahlukene ezithinta izakhiwo ezahlukene. Okuthakazelisayo enkulu stents ukuthi camera nge izinto polymeric futhi izinto zokwelapha (isib izidakamizwa cytotoxic anticancer). Stenting imithambo wenhliziyo catheters enjalo kungaba sinciphise izinga lokutholakala kwengculazi kumiswa zingcwecwe atherosclerotic. Kodwa kuwufanele ukukhumbula ukuthi ngokusebenzisa lezi stents ngesilinganiso ukuphulukiswa kwezindonga engaphakathi imithambo incipha, okuyinto into thrombosis ingozi.

Stenting imithambo wenhliziyo ncamashi ngendlela efanayo njengoba ibhaluni angioplasty. Yinye kuphela umehluko ngesikhathi stent ibhaluni abagqoke, igobolondo camera. Lapho wethula ipayipi ku le yenhliziyo Umthambo emgodleni isuswe, bese kufuthwe ibhaluni, le stent ngoba eqondisa indawo lapho i Umthambo is ayisesemikhulu. Ngakho, Expanded Umthambo odongeni luyaqina futhi wasisekela ngaphakathi.

Ngesikhathi sigaba samanje inhliziyo stents - zokwelapha ngaphandle yenhliziyo Umthambo dlula ngokuxhunyelelwa. Kufanele kuqashelwe omunye isici esihle stenting: the spasm kwemithambo yegazi yenhliziyo ngesikhathi ibhaluni angioplasty angagcina isilethikusebenza, okuyinto kungagwenywa ngokusebenzisa stent. Stenting lemithambo wenhliziyo manje - indlela ehlukile yenhliziyo Umthambo dlula ngokuxhunyelelwa. Ngaphezu kwalokho, uma ngokuhamba ekusebenzeni ibhaluni angioplasty ukuxhumelela imithambo yenhliziyo spazmiruyutsya, kungenzeka ukuthuthukiswa isilethikusebenza, futhi stent kulesi simo kusiza ukugwema lokhu isimo esibucayi. Lapho yenhliziyo Umthambo dlula ukuhlinzwa kwesigamu iziguli athuthukile stenosis we shunt. stenting lakhe okunye okuhle eziphindaphindiwe dlula yenhliziyo. stents Futhi senhliziyo - esikhundleni thrombolysis kanye ubuchwepheshe best for ekwelapheni acute isilethikusebenza ngqo amahora okuqala angu-sokuthuthuka.

Nokho, kukhona Izimo kule nqubo. Stent ukubekwa akunakwenzeka anezinhlaka eziya ziba ehlasela umzimba we nemithambo yegazi yenhliziyo. Futhi, isithiyo esingenakunqotshwa lincane (esingaphansi 2.8 mm) ububanzi we Umthambo ayisesemikhulu.

Ngokuba nokuvimbela izenzakalo thrombotic le nqubo wenziwa ku isizinda anticoagulants.

Ngemva kokuhlinzwa esinjalo, isiguli uhlala esibhedlela izinsuku 5-7 ubusuku nemini kweso lwezokwelapha. Postoperatively uyaqhubeka antiplatelet futhi anticoagulation yokwelapha.
