Nā maʻi puʻuwai puʻuwai maʻamau
ʻO ka maʻi puʻuwai puʻuwai
1 、 Congenital ： nā hemahema hānau
2. Ka hope:
1）Maʻi puʻuwai Rheumatic
Ke kumu nui
Mitral stenosis / Mitral incompetence
Aortic senosis / Aortic incompetence
Ka hāʻule ʻana o ka mitral
2）Maʻi puʻuwai rumatika ʻole
E like me ka ma'i ma'i ma'i 'elemakule ；Ma'i pu'uwai coronary myocardial infarction ； trauma nui ； ma'i bacteria o ka valve
Nā hemahema o ka laina hoʻololi valve maʻamau
-ʻO ka mana hoʻomalu transverse o ka suture ponoʻī ma ka pledget ʻaʻole maoli.
- He mau kuhikuhi maikaʻi a maikaʻi ʻole ka ʻōlelo hoʻohiki
- ʻO ke kaula humuhumu maʻalahi
- Hoʻohuli maʻalahi ka hoʻohiki
- He palupalu ka ʻōlelo hoʻohiki, a maʻalahi hoʻi e hoʻopaʻa a hoʻololi i ka wā e hoʻopili ai.Ma hope o ka humuhumu ʻana a me ka hoʻopaʻa ʻana, ua hoʻopaʻa ʻia nā welau ʻelua o ka gasket a ʻaʻole hiki ke hoʻoikaika ʻia
ʻO nā ʻano hou anti-entanglement valve sutures
●Pledget me ke kuhikuhi ʻole: ʻAʻole pono e hoʻoponopono kūikawā i ke kuhikuhi ʻōlelo hoʻohiki
●Suture me ka ʻole twining
● ʻOi aku ka maikaʻi no ke kauka lapaʻau i ʻoi aku ka maikaʻi o ka hana ʻana
● He kūpono no ka hoʻololi puʻuwai puʻuwai liʻiliʻi
ʻO ke kaʻina pani pani ʻana o ka valve aortic nui.
1. ʻO ka ʻokiʻoki a me ka hoʻokumu ʻana i ke kahe extracorporeal
2. ʻO ka ʻoki aortic .Ma hope o ka hana ʻana i ka cardiopulmonary bypass ， i ka hāʻule ʻana o ka mahana i 30 ℃, ua kāohi ʻia ka aorta piʻi, a ua hoʻokomo ʻia ka cardioplegia anuanu, ʻoiai ua hana ʻia ka hoʻoluʻu ʻana o ka naʻau.Ma hope o ka hopu ʻia ʻana o ka naʻau, ua hana ʻia kahi ʻoki aortic transverse a oblique paha, a ʻo ka hopena haʻahaʻa o ka ʻoki ʻana ma kahi o 1-1.5cm mai ka wehe ʻana o ke aʻa coronary pono. pani no ka maʻi pāpū aortic
3. Hoʻopili ʻia kahi laina huki ma kēlā me kēia o nā hui ʻekolu o ka valve aortic.
4. Ka wehe 'ana i ka valve Ua wehe kaawale 'ekolu lobes, waiho ka 2mm ma ka lihi.A laila ua wehe ʻia ka ʻiʻo calcified ma ke apo.Ua ana ʻia ke apo me ka mika valve e hoʻoholo ai i ka helu o ka valve prosthetic
5.Suture Ua hoʻohanaʻia ka 2-0 polyester pani pani no ke kuʻi moena ma waena mai luna a lalo.Ma hope o ka humuhumu ʻia ʻana o ke apo, pono e māhele like ʻia nā laina suture a hoʻokaʻawale ʻia ma waena o ke apo a me ka valve naʻau.ʻO 2mm ka lōʻihi o ka nila
6. implantation Ua hoʻopaʻa ʻia nā humuhumu a pau a ua hoʻokuʻu ʻia ka valve artificial ma lalo o ke apo valve e hōʻoia i ka paʻa ʻana o ka implantation a ʻaʻole i keakea ka valve artificial i nā puka coronary hema a me ka ʻākau.A laila ua nakinaki ʻia ka puʻupuʻu.Ua hōʻoia ka hoʻokolokolo hope ʻana ua maopopo ka wehe ʻana o ka coronary hema a me ka ʻākau
7. Holoi E holoi pono i ke aorta a me ka ventricle hema ma luna a ma lalo o ka valve prosthetic a hoʻopiha i ke aorta a me ka ventricle hema me ka paʻakai maʻamau.
8.Suturing Hoʻohana i ka 4-0 a i ʻole 5-0 polypropylene i ke kuʻi ʻana, ʻElua mau ʻoki aortic i hui pū ʻia.Pono e hoʻokuʻu ʻia ma mua o ka hoʻopaʻa ʻia ʻana o ka humuhumu hope.
Aortic valve pani pani ʻana- Polyester, polyester me ka hoʻohiki, Polypropylene
