Indwara zisanzwe z'umutima
Indwara z'umutima
1 、 Ivuka defect inenge ivuka
2 、 Inyuma ：
1 disease Indwara z'umutima
Impamvu nyamukuru
Mitral stenosis / Ubushobozi buke bwa Mitral
Aortic senose / Ubushobozi buke bwa Aortic
Kugabanuka kwa mitral
2 disease Indwara z'umutima zitari rubagimpande
Nka ischemia ishaje idakira disease Indwara yumutima yumutima myocardial infarction trauma ihahamuka rikomeye infection kwandura bagiteri ya valve
Ibibi bya gakondo ya valve ihindura umurongo
-Imbaraga zo kugenzura imbaraga za suture ubwazo kumihigo ni zeru.
-Imihigo ifite icyerekezo cyiza kandi kibi
-Suture twine byoroshye
-Imihigo irengaho byoroshye
-Imihigo iroroshye, kandi biroroshye guhagarika no guhindura iyo ipfundo. Nyuma yo kudoda no gupfundika, impande zombi za gaze zarazamutse kandi ntizishobora gukomera
Ubwoko bushya burwanya anti-entanglement valve suture
Gusezerana nta cyerekezo ： Nta mpamvu yo gukosora icyerekezo cy'imihigo byumwihariko
Ure Kudoda nta mpanga
Birakenewe cyane kubaga kugira uburambe bwiza bwo gukora
Bikwiranye no gusimbuza umutima valve gusimbuza
Kubaga aortic valve yo gusimbuza intambwe Intambwe zihariye:
1. Gutema no gushiraho uruzinduko rudasanzwe
2. Gutemagura Aortic. Nyuma yo gukora byipi yumutima ， mugihe ubushyuhe bwamanutse bugera kuri 30 ℃, aorta izamuka yarahagaritswe, kandi umutima ukonje watewe, mugihe hakozwe ubukonje bwumutima. Nyuma yo gufatwa k'umutima, hakozwe transvers ya transvers cyangwa oblique aortic, hanyuma impera yo hepfo yigitereko yari nka 1-1.5cm kuva hafunguwe imiyoboro yimitsi yimitsi. gusimbuza indwara ya aortic valve
3. Umurongo wo gukwega ushushanyije kuri buri kimwe mu bice bitatu bya valve ya aortic.
4. Gukuraho valve Imyanya itatu yakuweho ukwayo, hasigara 2mm kuruhande. Noneho tissue yabazwe kumpeta yakuweho. Impeta yapimwe na metero ya valve kugirango hamenyekane umubare wa prostate
5.Suture Urudodo rwo gusimbuza polyester 2-0 rwakoreshejwe mugutunganya matelas rimwe na rimwe kuva hejuru kugeza hasi. Impeta imaze kudoda, imirongo ya suture igomba kugabanwa neza kandi ikagereranywa hagati yimpeta na valve yumutima. Intera y'urushinge muri rusange yari 2mm
6. Gutera suture zose zarakomerekejwe hanyuma valve yubukorikori isunikwa munsi yimpeta ya valve kugirango hemezwe ko iyatewe ryakozwe kandi ko valve yububiko itabangamiraga gufungura ibumoso niburyo bwa coronari. Hanyuma ipfundo ryaboheshejwe umwe umwe. Isuzuma rya nyuma ryemeje ko gufungura ibumoso n'iburyo bya koronari byasobanutse
7.Kwoza neza usukure neza aorta na ventricle ibumoso hejuru no munsi ya valve ya prostate hanyuma wuzuze aorta na ventricle ibumoso hamwe na saline isanzwe.
8.Gushushanya Ukoresheje 4-0 cyangwa 5-0 polypropilene kugirango ushushanye, Ibice bibiri bya aortic byashushanyije bikurikiranye. Venting igomba gukorwa mbere yuko ubudozi bwa nyuma bukomera.
Aortic valve isimbuza suture- Polyester 、 polyester hamwe n umuhigo 、 Polypropilene
