Ukubuka konke

I-DCA, noma i-coronary atherectomy eyinkomba inqubo encane yokuhlasela yokususa ukuvinjelwa emithanjeni ye-coronary ukwenza ngcono ukugeleza kwegazi kuye emisipha yenhliziyo futhi kuthuthukise ubuhlungu.

Okokuqala, i-anesthesia yendawo iyindikindiza indawo yezinhlungu. Bese udokotela efaka inaliti emthanjeni wobufazi, umthambo wehla ngomlenze. Udokotela ufaka ucingo lwesiqondisi ngenaliti abese esusa inaliti. Uyifaka esikhundleni sayo ngesingeniso, insimbi eyi-tubular enamachweba amabili asetshenziselwa ukufaka izinto eziguquguqukayo njenge-catheter emthanjeni wegazi. Lapho isingenisi sesikhona, i-guidewire yangempela ithathelwa indawo yucingo oluhle kakhulu. Lolu cingo olusha lusetshenziselwa ukufaka ipayipi lokuxilonga, ishubhu elide eliguquguqukayo, emthanjeni futhi liwuqondise enhliziyweni. Udokotela bese ekhipha ucingo lwesibili.

Nge-catheter ekuvulekeni komunye wemithambo yegazi, udokotela ujova udayi bese ethatha i-X-ray. Uma ikhombisa ukuvinjelwa okwelaphekayo, udokotela usebenzisa enye intambo yokuqondisa ukususa i-catheter yokuqala bese eyifaka esikhundleni se-catheter eqondisayo. Ngemuva kwalokho ucingo olwalusetshenziselwa ukwenza lokhu luyasuswa bese kufakwa olucwebezelayo oluqhubekele phambili ngaphesheya kokuvinjelwa.

Enye i-catheter eyenzelwe ukusika izilonda nayo ithuthukile kuyo yonke indawo yokuvimba. Ibhaluni elinengcindezi ephansi enamathiselwe eceleni komsiki, ligcwele umoya, liveza okokusebenza kwesilonda kumsiki.

Iyunithi yokushayela ivuliwe, okwenza umsiki aphenduke. Udokotela uqhubekisela phambili isigwedlo kwiyunithi yokushayela ethi yona iqhubekisele phambili umsiki. Izingcezu zokuvaleka ezisikayo zigcinwa engxenyeni ye-catheter ebizwa nge-nosecone ize isuswe ekugcineni kwenqubo.

Ukushintshanisa ipayipi lapho ugcizelela futhi uchitha ibhaluni kwenza ukuthi kube lula ukusika ukuvinjelwa kunoma iyiphi indlela, okuholele ekwehliseni umfaniswano. I-stent nayo ingafakwa. Lesi yisikafula sensimbi esifakwe ngaphakathi komthambo we-coronary ukugcina umkhumbi uvulekile.

Ngemuva kwenqubo, udokotela ujova udayi bese ethatha i-X-ray ukubheka ushintsho emithanjeni yegazi. Ngemuva kwalokho i-catheter iyasuswa bese inqubo isiphelile.
