M'malo vavu mtima. Mitundu ya ziwalo.

Mtima - mpope zachilengedwe zimene zimachititsa magazi zimafala mu thupi ndi munthu ndi kudyetsa izo zimakhala thupi lonse. Anatomically mtima imakhala ya zipinda zinayi ndipo mavavu anayi. ntchito za mtima anaika mu njira yakuti pa malo ena nthawi ndi kutsegula kwa valavu ndi kutseka ena kuonetsetsa yachibadwa magazi. Kulephera valavu aliyense kumabweretsa kusokonezeka kwa kotunga magazi. Pankhaniyi, zambiri adasonkhananso kwa prosthesis (m'malo) vavu mtima.

M'malo mtima vavu - opaleshoni, kumafuna kuika prosthesis mu malo vavu wosadziŵa. Nthawi zambiri, opaleshoni imeneyi umalimbana kukonza kobadwa nako kapena kugula kusintha kapangidwe ndi ntchito ya dongosolo valavu wa mtima, zimene sizingasinthe njira chilango pulasitiki. A angapo zaka zapitazo, apulasitiki vavu mtima kukhala woopsawo thanzi ndi moyo wa ntchito. Komabe, mu m'badwo ano si ndithu chinthu wamba, chomwe nthawi zambiri njira yokhayo kubwezeretsa thanzi la mtima ndi thupi lonse.

Mwa zizindikiro kwa m'malo a munthu vavu mtima :

• kusintha aakulu valvular, zimene zimachititsa kuti aziyenda osauka;
• mwapang'onopang'ono mtima kulephera;
• kupanda mankhwala opha tizilombo;
• embolic zosokonezeka;
• Zizindikiro echocardiographic kuwonongeka kwa mavavu ndi vegetations.

M'malo mavavu mtima contraindicated odwala ndi matenda aliwonse, monga mu nkhani iyi pali chiopsezo osauka infective endocarditis pambuyo opaleshoni.

Pa kutaya opaleshoni ano, pali 2 mitundu ya ziwalo kwa mavavu mtima.

Yoyamba zikuphatikizapo ziwalo makina. Iwo akutchedwanso ziwalo yokumba. Mawotchi vavu chikuphatikizapo vavu obturator mchitidwe mtundu umene chopangidwa kuchokera ku yokumba. The sangathe pogwiritsa ndi kufunika kwa moyo wonse anticoagulant phwando - mankhwala kuchepetsa magazi coagulability. Choncho, ziwalo makina amadziŵika ndi zodalirika, moyo utumiki (moyo) ndipo mulibe kusowa kuti m'malo. Komabe, moyo wake wonse munthu ali kukonzekera mwapadera.

mtundu wina wa ziwalo ndi kwachilengedwenso mavavu, amene, monga dzina lake likunenera, ndi anachokera ku zinthu. The mfundo izi ndi equine pericardium kapena minofu porcine. Chifukwa cha prosthesis ali ndi zachilengedwe obturator amafotokozera ndi kutseka kuti uchiwo usatuluke atatu. Chifukwa n'zofanana ndi mavavu zachilengedwe, apulasitiki kwachilengedwenso ankaona yabwino yothetsera. zipangizozi yodziwika ndi kulemera otsika ndi kukula, omwe pafupifupi kumatha chiopsezo thrombosis kapena thromboembolism. Komabe, prosthesis kwachilengedwenso ndi atengeke kudzitsitsa pa nthawi. moyo wake utumiki anatsimikiza ndi zaka wodwalayo komanso matenda alipo. Komabe, tisaiwale kuti ndondomeko ya kunyoza vavu kwambiri kubweza ndi zaka.

Asanachite opareshoni, mtima vavu m'malo pakati pa mtima ndi dokotala kuonedwa kucheza mutu umene - kusankha mtundu winawake wa valavu.

Pambuyo apulasitiki vavu mtima bwinobwino, pakubwera nthawi konzanso. Patangotha miyezi 6 ayenera opareshoni, ndi mwapadera kuti aziona chikhalidwe chawo. Mtheradi contraindication pambuyo mtundu wa opaleshoni ndi zinthu zakuthupi. Wodwala ayenera kutsatira zakudya zokhala ndi osachepera kuchuluka kwa mchere umene Polemeretsedwa magnesium ndi potaziyamu.

The Vuto ambiri pambuyo opaleshoni mtima vavu m'malo ndi chitukuko cha endocarditis infective. Ngati muyeso njira dokotala n'kukulemberani angapo mankhwala ndi zowonjezera zakudya.
