Ngā Rauemi Tuitui Pai rawa atu mō te Pokanga Ngākau

He mara uaua te pokanga ngākau me te hiahia ki ngā rauemi tika me te pono hei whakarite i ngā putanga pai rawa atu mō ngā tūroro. I roto i ēnei rauemi, he mea nui ngā tuitui ki te pupuri i te pono o ngā whakatikatika pokanga, inā koa i roto i ngā tikanga uaua e pā ana ki ngā oko toto me te ngākau. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā rauemi tuitui pai rawa atu mō te pokanga ngākau, me te arotahi ki ō rātou āhuatanga, ngā painga, me ngā whakamahinga motuhake hei āwhina i ngā tohunga hauora ki te whakatau whai whakaaro.

He aha te mea nui ki te whiriwhiri i te rauemi tuitui tika

I roto i te pokanga ngākau, he mea nui te whiriwhiri i te rauemi tuitui tika nā te mea ka pā tika ki te angitu o te pokanga me te tukanga whakaora. Me kaha ngā tuitui kia mau ai ngā kiko i raro i te pēhanga, ā, me ngawari hoki kia kore ai e kino. Hei tāpiri, me tino pai te whakahaere, me iti te tauhohenga o te kiko, me te haumaru o te pona kia kore ai e raruraru.

Ngā Rauemi Tuitui Pai rawa atu mō ngā Tukanga Ngākau

1.Ngā Tuitui Polyester

He rauemi tuitui hangai te polyester, kāore e mimitihia, e whakamahia whānuitia ana i roto i ngā pokanga ngakau. He kaha te kume me ngā āhuatanga whakahaere pai rawa atu, he mea tino pai mō te anastomosis vascular me ngā tikanga whakakapinga takirere. He tino pai ngā tuitui polyester mō tōna roa me te iti o te tauhohenga kiko, ka whakaiti i te tūponotanga o ngā urupare mumura. Hei tauira, i roto i te grafting bypass artery coronary (CABG), ka āwhina ngā tuitui polyester ki te whakarite i ngā hononga haumaru me te roa i waenga i ngā grafting me ngā oko toto taketake.

2.Ngā Tuitui Polypropylene

Ko te polypropylene tētahi atu whiringa rongonui mō ngā mahi cardiovascular, e mōhiotia ana mō tōna ngāwari me tōna hototahi ki te koiora. He rauemi kore e mimiti, he mea whai hua i roto i ngā pokanga e hiahia ana kia roa te tautoko kiko. Ka whakaitihia e tōna mata maeneene te whara kiko i te wā e haere ana, ka pai mō ngā whakatikatika uaua ngawari. Ko te ātete o te polypropylene ki ngā mate me te iti o te uruparenga kiko ka waiho hei tuitui pai mō ngā tikanga pēnei i te whakatikatika aneurysm aortic.

3.Ngā Tuitui ePTFE (Polytetrafluoroethylene Whakawhanui)

He tino ātete ngā tuitui ePTFE ki te whakarerekētanga o te āhua, ā, he mea pai rawa atu ēnei mō ngā whakatikatika ngakau me te ahotea nui. He tino whai hua ēnei i roto i ngā pokanga e whakamahi ana i ngā tākai hangai, nā te mea he pai te hototahitanga o ngā kiko me te iti o te waku. He maha ngā wā ka whiriwhiria e ngā taote pokanga te ePTFE nā tōna kaha ki te whakahaere i ngā hononga uaua o te toto me te kore e tapahi i ngā pakitara o te toto, ā, ka ārai i ngā raruraru i muri i te pokanga pērā i te toto o te raina tuitui.

Ngā Tuitui Mimihia, me ngā Tuitui Kore-Mimihia

He mea nui te mārama ki ngā rerekētanga i waenga i ngā tuitui mimiti me ngā tuitui kore mimiti hei whiriwhiri i te rauemi tika mō ngā tikanga mahi ngakau.

•Ngā Tuitui e Mimia ana:Ka pakaru haere ēnei tuitui i roto i te tinana, ā, ka mimiti haere i roto i te wā. He mea noa ēnei i ngā wā e ranea ana te tautoko patunga rangitahi. Heoi, i roto i ngā pokanga ngakau, he iti ake te kitea o ngā tuitui mimiti nā te mea kāore e whakarato i te tautoko pumau e hiahiatia ana mō ngā whakatikatika nui.

•Ngā Tuitui Kāore e Mimia:E ai ki te ingoa, kua hangaia ēnei tuitui kia noho tonu ki roto i te tinana, kia tangohia rā anō rānei. Ko ngā tuitui kāore e mimitia pērā i te polyester, te polypropylene, me te ePTFE ngā whiringa paerewa mō ngā tikanga cardiovascular, e whakarato ana i te pumau mō te wā roa, me te whakaiti i te mōrearea o te whakawhānui o te aneurysm.

Te Tūranga o te Rahi o te Tuitui i roto i te Pokanga o te Ngākau

He rite tonu te hiranga o te whiriwhiri i te rahi tika o te tuitui ki te rauemi tonu. I roto i ngā pokanga ngakau, he maha ngā wā ka whakamahia ngā rahi tuitui pai ake (pēnei i te 6-0, 7-0 rānei) nā te mea ka whakaitihia te whara o te kiko, ka whakarei ake hoki i te tika, inā koa i roto i ngā hanganga uaua ngawari. Heoi, ka taea te whakamahi i ngā rahi nui ake i ngā wāhi e hiahia ana ki te kaha me te tautoko tāpiri, pērā i te whakatikatika aorta.

Akoranga Take: Te Angitu i roto i te Tāruatanga o te Arorangi Koronari (CABG)

I roto i tētahi rangahau i uru atu ai ngā tūroro CABG, i whakaatuhia te whai huatanga o ngā tuitui polyester ki te whakatutuki i ngā hononga angitu. I kitea e ngā taote pokanga ko te kaha kume teitei o te polyester me te iti o te tauhohenga kiko i whai wāhi ki te whakaiti i ngā reiti o ngā raruraru i muri i te pokanga, me te whakapai ake i te āheinga whānui o te hononga. E whakaatu ana tēnei taunakitanga i te pai o te rauemi mō ngā tikanga cardiovascular nui e hiahiatia ana ngā tuitui pakari me te pono.

Ngā Tohutohu mō te Pupuri i te Pono o te Tuitui

Ka pā kino te whakahaere tika i ngā tuitui i te wā pokanga ki ngā hua. Me karo ngā taote pokanga i te taumaha rawa i te wā e herea ana ngā pona, nā te mea ka raru pea te kiko, ka whati rānei te tuitui. Hei tāpiri, mā te whakarite kia iti te whakahaere me te whakamahi i ngā tikanga tika mō te here i ngā pona ka āwhina i te pupuri i te hanganga o ngā tuitui, ka whakarei ake i tō rātou mahi i te wā e whakaora ana.

Te Anamata o ngā Rauemi Tuitui i roto i te Pokanga Ngākau

Kei te whanake tonu ngā whanaketanga o te hangarau tuitui, me te arotahi ki te whakarei ake i te haumaru o te tūroro me te whakapai ake i ngā putanga pokanga. Kei te tūhuratia ngā auahatanga pēnei i ngā paninga huakita me ngā tuitui koiora e whakatairanga ana i te whakaora i roto i ngā tono cardiovascular. Ko te whāinga o ēnei whanaketanga he whakaiti i ngā reiti mate me te whakatairanga i te whakaurunga pai ake ki te kiko, e tuku ana i ngā mea whakahihiri mō te heke mai o te pokanga cardiovascular.

He whakatau nui te whiriwhiri i te rauemi tuitui tika mō te pokanga ngākau, ā, ka pā nui ki ngā hua o te tūroro. He tino kaha, he roa, he iti hoki te tauhohenga o ngā kiko e ngā rauemi pēnei i te polyester, te polypropylene, me te ePTFE, ā, he pai rawa atu ēnei mō ngā tikanga uaua o te ngākau. Mā te mārama ki ngā āhuatanga ahurei o ēnei tuitui me te whakaaro ki ngā āhuatanga pēnei i te rahi o te tuitui me ngā tikanga whakahaere, ka taea e ngā taote pokanga te whakatau whai whakaaro hei whakarei ake i te angitu o te pokanga me te whakatairanga i te whakaora pai ake.

Mō ngā tohunga hauora e hiahia ana ki te whakapai ake i ā rātou tikanga pokanga me ngā putanga, he mea nui te whakapau wā ki te whiriwhiri i te rauemi tuitui tika. Ahakoa kei te mahi koe i ngā whakatikatika auau, i ngā hanganga uaua uaua rānei, mā te tuitui tika ka nui te rerekētanga.
