Izifo ezivamile ze-valve yenhliziyo


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isifo senhliziyo se-Valvular

1, Ukuzalwa: ukukhubazeka kokuzalwa

2, Okulandelayo:

1) Isifo senhliziyo esine-Rheumatic

Imbangela enkulu

I-Mitral stenosis / ukungasebenzi kahle kwe-Mitral

I-senosis ye-aortic / ukungasebenzi kahle kwe-aortic

Ukuvuvukala kwe-mitral

2) Isifo senhliziyo esingesona isifo samathambo

Njenge-ischemia yasebekhulile engapheli; Isifo senhliziyo se-myocardial infarction; ukuhlukumezeka okukhulu; ukutheleleka kwebhaktheriya kwe-valve

Okubi komugqa wendabuko wokushintsha i-valve

-Amandla okulawula aguquguqukayo we-suture ngokwayo esibambiso ngokuyisisekelo ayiziro.

-Isibambiso sinezikhombisi-ndlela ezinhle nezingezinhle

-I-suture twine kalula

-Isibambiso sigingqika kalula

-Isibambiso sithambile, futhi kulula ukusiminyanisa nokonakala lapho ufipha. Ngemuva kokuthunga nokubopha, iziphetho zombili ze-gasket zikhuphukele phezulu futhi azikwazi ukuqiniswa

Ama-valve e-anti-entanglement sutures yohlobo olusha

● Isethembiso ngaphandle kwesiqondiso :Asikho isidingo sokulungisa isiqondiso sesibambiso ngokukhethekile

●Suture ngaphandle kokusonta

●Okufanele kakhulu udokotela ohlinzayo abe nolwazi olungcono lokuhlinza

●Ifanele ukushintshwa kwevalvu yenhliziyo engenele kancane

Ukuhlinzwa okuyinhloko kokubuyisela i-aortic valve Izinyathelo eziqondile:

1. Ukusika nokusungulwa kokujikeleza kwe-extracorporeal

2. Ukusikwa kwe-aortic. Ngemva kokuhlinzwa kwe-cardiopulmonary bypass , lapho izinga lokushisa lehla laya ku-30℃, i-aorta ekhuphukayo yayivinjiwe, futhi kwafakwa i-cardioplegia ebandayo, kuyilapho ukupholisa kwenhliziyo kwenziwa. Ngemuva kokuboshwa kwenhliziyo, i-aorta eguquguqukayo noma e-oblique yenziwa, futhi isiphetho esiphansi sokusika sasicishe sibe ngu-1-1.5cm ukusuka ekuvulekeni komthambo we-coronary ongakwesokudla.Ukuvuleka komthambo we-coronary kwesokunxele nakwesokudla kwabonwa ukuze kuqinisekiswe isidingo se-valve. ukushintshwa kwesifo se-aortic valve

3. Ulayini wokudonsa uxhunywe ekuhlanganeni ngakunye kwezintathu ze-aortic valve.

4. Ukususwa kwevalvu Amalobe amathathu akhishwe ngokuhlukana, kwashiya u-2mm emaphethelweni. Kwabe sekukhishwa izicubu ezibaliwe eringini. Iringi ikalwe ngemitha yevalvu ukuze kutholwe inani levalvu yokufakelwa

5.I-Suture Intambo engu-2-0 yokubuyisela i-polyester yasetshenziselwa ukuthungatha kukamatilasi ngezikhathi ezithile ukusuka phezulu kuye phansi. Ngemva kokuba indandatho ithungiwe, imigqa ye-suture kufanele isakazwe ngokulinganayo futhi ihlukaniswe phakathi kwendandatho ne-valve yenhliziyo yokwenziwa. Ibanga lenaliti ngokuvamile lalingu-2mm

6. ukufakwa kwawo Wonke ama-sutures afinyezwa futhi i-valve yokwenziwa yaphushwa ngaphansi kweringi ye-valve ukuze kuqinisekiswe ukuthi ukufakelwa kwakusendaweni nokuthi i-valve yokwenziwa yayingavimbeli ukuvuleka kwe-coronary kwesokunxele nakwesokudla. Kwabe sekuboshwa ifindo ngalinye. Ukuhlolwa kokugcina kwaqinisekisa ukuthi ukuvuleka kwe-coronary kwesokunxele nakwesokudla kwakucacile

7.Ukugeza Gcoba kahle i-aorta ne-ventricle yesokunxele ngenhla nangaphansi kwevalvu yokufakelwa bese ugcwalisa i-aorta ne-ventricle yesokunxele ngosawoti ojwayelekile.

I-8.I-Suturing Ukusebenzisa i-4-0 noma i-5-0 i-polypropylene ukuthungatha, ukucutshungulwa kwe-aortic okubili kwahlanganiswa ngokulandelana. Ukukhipha umoya kufanele kwenziwe ngaphambi kokuba umthungo wokugcina uqiniswe.

I-aortic valve replacement suture- I-Polyester, i-polyester ene-pledget, i-Polypropylene
