Replacement mwoyo vharafu. Marudzi prostheses.

Heart - wechisikigo Pombi rinogumbusa ropa kutenderedza yose muviri uye munhu uye zvokudya zvose munyama muviri. Anatomically, mwoyo ine makamuri mana uye mana mavharuvhu. zvinoitwa nomwoyo wakaradzikwa nenzira kuti pane imwe nguva iri kuvhurika imwe vharafu nokuvhara mumwe kuitira ropa chokubuda chakaipa. Kukundikana chero vharafu kunotungamirira nokuvhiringidzirwa ropa rive. Muchiitiko chino, kazhinji unodzokera kuna prosthesis (yokutsiva) mwoyo vharafu.

Replacement mwoyo vharafu - kuvhiyiwa, kunosanganisira kugadzwa prosthesis panzvimbo sagona vharafu. Kakawanda, kuvhiya ichi nechinangwa kururamisa vachiberekwa kana vawana kuchinja marongerwo uye kushanda vharuvhu ezvinhu mwoyo, risingagoni kugadziriswa nzira epurasitiki kururamiswa. Vanechitsama emakore apfuura, prosthetic mwoyo vharafu kuti utano uye upenyu hwokushanda. Zvisinei, munguva yanhasi iri yakati inozivikanwa, iri kazhinji chete nzira kudzorera utano mwoyo uye rose muviri.

Pakati zvairatidza kuti yaitsiva moyo vharafu :

• zvakakomba valvular kuchinja, izvo zvinozoita kuti murombo kutenderera;
• mberi mwoyo kutadza;
• ineffectiveness zvemishonga inorwisa mabhakitiriya kurapa;
• embolic yematambudziko;
• echocardiographic zviratidzo kukuvara mavharuvhu uye vegetations.

Replacement mwoyo mavharuvhu ari contraindicated pavarwere vane chirwere chipi, sezvo iri mhosva pane mukuru pangozi yokuita infective endocarditis pashure kuvhiyiwa.

Dzinoshandiswa wokuvhiya ano, pane 2 mhando prostheses kuti mwoyo mavharuvhu.

Wokutanga mhando zvinosanganisira zvemaziso prostheses. Vanewo kunzi chakagadzirwa prostheses. Zvokuimba vharafu rinosanganisira vharafu obturator Kufananidzira mhando riri kugadzirwa kubva chakagadzirwa zvinhu. Zvakaipira mudziyo uyu kudiwa kwoupenyu hwose anticoagulant kugamuchirwa - zvinodhaka kuti kudzikisa ropa coagulability. Saka zvemaziso prostheses vari kusiyaniswa kuvimbwa, upenyu basa (nokuti upenyu) uye hapana chikonzero kutsiviwa. Zvisinei, vamwe hwake munhu ane kugadzirira inokosha.

Rumwe rudzi prostheses vari zvoutachiona mavharuvhu, iyo, sezvo zita ravo vachireva, vane mavambo vokubereka. The mashoko aya ndiwo equina pericardium kana porcine tishu. Somugumisiro yacho prosthesis ane dzinongoitika obturator chinhu pamwe ichibhabhamisa matatu. Nokuda zvakafanana nematauriro yepanyama mavharuvhu, utachiona prosthetic vaiona chinetso. mano aya ne pasi uremu uye size, izvo anenge anobvisa ngozi thrombosis kana thromboembolism. Zvisinei, zvipenyu prosthesis riri kubatwa kudzikisirana pamusoro nguva. upenyu nebasa rayo vagara vandifungira murwere zera uye ake ezvinhu aripo dzokurapa. Zvisinei, zvinofanira kucherechedzwa kuti muitiro uchinyara pamusoro vharuvhu yekudyidzana DZEMUNHU DZINODZORA nezera.

Asati avhiyiwa, mwoyo vharafu pakutsiva pakati murwere uye chiremba raizoitwa kukurukurirana, dingindira iyo - kusarudza imwe mhando vharafu.

Mushure prosthetic mwoyo vharuvhu zvapedza, anouya rokuchinjwa nguva. Mukati 6 months of vakavhiyiwa vanofanira, uchinyanya kufunga kuongorora avo ezvinhu. Mhedziso contraindication pashure kwakadai Kuvhiya zviri mumuviri mabasa. Murwere anofanira kuomerera kudya ine risingamboshandisi yakawanda munyu, iyo kunowedzerwa mu magnesium uye potassium.

The inonyanya kuomesa pashure kuvhiyiwa mwoyo vharafu yokutsiva ndiko kukura kwakaita infective endocarditis. Kuzvidzivirira nechiyero chiremba prescribes dzinoverengeka mishonga uye Mishonga zvokuwedzera.
