Ezitshintshwayo yentliziyo nokufakelwa. Types of zitho.

Intliziyo - nempompo zendalo ebangela igazi ukuze ujikeleze lonke umzimba kunye umntu kwalusa kuyo zonke izicwili zomzimba. Anatomically, intliziyo iqulathe yokwayama ezine bevala, ezine. umsebenzi wentliziyo echazwe ngendlela yokuba kwindawo ethile ixesha ukuvulwa isivingco nokuvala enye ukuqinisekisa ukuhamba kwegazi eqhelekileyo. Ukusilela nawuphi na vana kukhokelela ukuphazamiseka igazi. Kulo mzekelo, badla kubhenela afakelweyo (replacement) yentliziyo nokufakelwa.

Ezitshintshwayo yentliziyo nokufakelwa - utyando, kuquka ukufakela afakelweyo endaweni valve engathethekiyo. Amaninzi, kulo utyando sijoliswe ukulungisa utshintsho iziphene okanye abazifumene kubume umsebenzi kwenkqubo vana intliziyo, zibe alungiswe iindlela wokulungiswa zeplastiki. Isibini eminyaka eyadlulayo, ezase yentliziyo nokufakelwa ukuba yingozi empilweni kunye nobomi nokusebenza. Noko ke, namhlanje zako Kuyaziwa, nto leyo edla yodwa indlela ukubuyisela impilo intliziyo wonke umzimba.

Phakathi izinto ezibonisa ukuba ukutshintshwa isivingco intliziyo :

• iinguqu ezinkulu valvular, akhokelela kwegazi;
• Ukungaphumeleli inhliziyo okuqhubekayo;
• kwawo unyango isibulala-zintsholongwane;
• iingxaki embolic;
• Iimpawu echocardiographic lomonakalo iivelufa kunye threatened.

Ezitshintshwayo kwemithambo ngentliziyo contraindicated kwizigulane kunye naluphi na usuleleko, njengoko kule meko kukho ingozi enkulu yokuba endocarditis infective emva kotyando.

Ukuba ziyisebenzise kotyando mihla, kukho 2 iintlobo zitho ukuba kwemithambo yenhliziyo.

Uhlobo lokuqala luquka zitho mechanical. Zibizwa kwakhona zitho ngumntu. umphini Mechanical luquka uhlobo element vana obturator leyo yenziwa ukusuka izinto zedolophu. Engxakini kule divaysi imfuno ubomi anticoagulant yokwamkela - iziyobisi kwabancinane coagulability igazi. Ngoko ke, ezi zitho mechanical ahluka yi ukuthembeka, ubomi inkonzo (ubomi) kwaye akukho mfuneko yokuba kufakwe. Nangona kunjalo, bonke ubomi bakhe indoda ukwenza amalungiselelo akhethekileyo.

Olunye uhlobo zitho kwezivalo zebhayoloji, leyo, njengegama yabo, sibe imvelaphi eziphilayo. Izinto ezi ke pericardium equine okanye inyama kweeHagu. Ngenxa yale afakelweyo unalo obturator element yendalo enezinto ezintathu. Ngenxa ukufana kwemithambo zendalo ezase bemvelo ingqalelo isisombululo ilungileyo. Ezi zixhobo luphawulwa ubunzima eliphantsi kunye nobungakanani, apho phantse ishenxisa ingozi thrombosis okanye thromboembolism. Nangona kunjalo, lo afakelweyo begazi uthambekele ekwehleni ngokuhamba kwexesha. umphefumlo wayo wenkonzo emiselwe ubudala yomguli kunye neemeko zonyango ezikhoyo. Nakuba kunjalo, kufanele kuqatshelwe ukuba inkqubo ukuthotywa ivelufa ukucola kakhulu phantsi kunye nobudala.

Ngaphambi kokuba ahlinzwe, yentliziyo nokufakelwa replacement phakathi umguli kunye nogqirha ukuba kubanjwa incoko, umxholo apho - ukukhetha uhlobo oluthile vana.

Emva kokuba yentliziyo nokufakelwa zokufakelwa igqityiwe ngempumelelo, kuza ixesha kwimeko yesiqhelo. Kwiinyanga ezi-6 kufuneka iqhutywe, kunye ingqalelo ekhethekileyo esweni imeko yabo. contraindication Absolute emva olu hlobo lotyando yimisebenzi yomzimba. Isigulane kufuneka esitya ukutya equlathe isixa ubuncinane ityuwa, nto leyo nithi magnesium potassium.

Obona bunzima eqhelekileyo emva kokuba ahlinzwe ngenxa yentliziyo nokufakelwa nokutshintsha uphuhliso lwe endocarditis infective. Njengenyathelo lokuthintela ugqirha ubeka inani amayeza kunye nezongezo zokutya.
