Nyowani-mhando anti-entanglement valve sutures
● Pledget pasina gwara: Hapana chikonzero chekugadzirisa dhizaini yakananga
● Suture isina kuruka
● Zvakanyanya zvakakodzera kuti chiremba anovhiya ave neruzivo rwekushanda rwuri nani
● Inokodzera zvishoma zvishoma invasive heart valve replacement
Main aortic valve replacement surgery Matanho chaiwo:
1. Incision uye kugadzwa kweextracorporeal circulation
2. Aortic incision.Mushure mekuvhiyiwa kwecardiopulmonary bypass , apo tembiricha yakadzika kusvika ku30 ℃, iyo aorta inokwira yakavharika, uye inotonhora cardioplegia yakapinzwa, ukuwo kutonhora kwemoyo kunoitwa.Mushure mekusungwa kwemwoyo, kutenderera kana oblique aortic incision yakaitwa, uye kuguma kwepasi kwekucheka kwaiva pamusoro pe 1-1.5cm kubva pakuvhura kwekona yekona yekona.Kuruboshwe uye kurudyi coronary artery kuzarura kwakaonekwa kuti kusimbise kudiwa kwevhavha. kutsiva aortic valve chirwere
3. Mutsara wekukwevera wakaiswa pane imwe neimwe yezvikamu zvitatu zvevharuvhu yeaortic.
4. Kubviswa kwevhavha Matatu matatu akabviswa zvakasiyana, achisiya 2mm kumucheto.Ipapo chidimbu chakaverengerwa pachindori chakabviswa.Ring yakapimwa nemita yevharuvhu kuona nhamba yevharuvhu yeprosthetic
5.Suture Iyo 2-0 polyester inotsiva shinda yakashandiswa kune intermittent metiresi suture kubva kumusoro kusvika pasi.Mushure mekunge mhete yakasonwa, mitsetse ye suture inofanira kugoverwa zvakaenzana uye yakaenzana pakati pemhete nevhavha yemwoyo yakagadzirwa.Kureba kwetsono kwaiwanzoita 2mm
6. kuiswa Kwese sutures yakasimudzwa uye chivharo chekugadzira chakasundirwa pasi pechindori chevharuvhu kuti chisimbise kuisirwa kwaive panzvimbo uye kuti chivharo chekugadzira chakanga chisingavharidzi kuruboshwe uye kurudyi coronary kuzarura.Ipapo pfundo rakasungwa rimwe nerimwe.Ongororo yekupedzisira yakasimbisa kuti kuvhurwa kwekona yekuruboshwe nekurudyi kwaive kwakajeka
7.Kugeza Nyatsotsvaira aorta uye kuruboshwe ventricle kumusoro uye pasi pevhavha yeprosthetic uye uzadze aorta uye kuruboshwe ventricle nesaline yakajairika.
8.Suturing Kushandisa 4-0 kana 5-0 polypropylene kuti suture, Two aortic incisions were sutured consecutively.Venting inofanira kuitwa musono wekupedzisira usati wasimbiswa.
