DMF yomntwana

I-DMZHP yinkcazo yesiphene se-septum ye-interventric in the fetus, oko kukuthi, i-defenital defect of this organ.

I-DMF ye-fetus - izizathu

Kukho izizathu ezibalulekileyo zesifo senhliziyo esiswini:

1. Heredity . Iintlobo eziphene zesifo senhliziyo okanye ezinye izitho ezidluliselwa ngelifa kwaye kungekhona kuphela kubazali kumntwana. Umngcipheko we- CHD , kubandakanywa ne-DMF yomntwana, kwakhona xa izidalwa zentliziyo ziye zahlangana nazo kwizizukulwana zangaphambili, kunye nezihlobo eziseduze okanye kwezinye iintsapho kunye nale ntsapho.
2. Ukuphazamiseka kwentuthuko yentliziyo ebusweni . Iyenzeka ngenxa yezinto ezinokuthi zithintela i-fetus ngethuba lokuphuhliswa kwe-embryonic: usulelo, ukuxhatshazwa kweendlela ezahlukeneyo, iziphumo ezimbi ezingqongileyo.

Ngamanye amaxesha ezi zibini zidibeneyo.

Iintlobo zeVSD kumntwana

I-septum ye-interventricular ihlukaniswe ngamacandelo amathathu ngokubhekiselele kwisakhiwo sayo: i-membrane ephezulu, i-muscular middle kunye nengxenye engezantsi. Ngokuxhomekeka kwisahlulo se-VSW, i-VSW iyahlula:

• Iintsilelo zesahluko somlenze, okanye umtshato - phantsi kwesiphakamiso se-aortic kunye nomzobo we-pulmonary, ungavalwa ngokuzimeleyo ngamanani amancinci);
• I-VSD enomntwana ebusweni yintsipho ehlangeneyo esesisuncle semisipha, kodwa enye yamaphethelo yenziwa ngamathambo axhumeneyo enxalenye ye-septum;
• i-defect kwingxenyeni ye-muscular - zide zivela kwiiphini kwiisisipha ze-muscle;
• ukugqitywa kwee-septum;
• peregrevevyy DMZHP - ngasentla kwinqanaba eliphezulu.

Fit:

• Mkhulu - ububanzi bephene bukhulu kunokuba ububanzi be-aorta kunye neengcinezelo zombini zombini zilingana;
• i-defect isingaphantsi kobubanzi be-aorta kunye noxinzelelo kwi-ventricle efanelekileyo ngu-50% weengcinezelo ngakwesobunxele;
• encinci - xa isiphene sincinci kangangokuba ukunyanzeliswa kwi-ventricle efanelekileyo kungekho ngaphaya kwama-25%, ngokuqhelekileyo kubonakala kungenakwenzeka.

Zonke i-VSD kufuneka zifunyenwe kwisesibini ye- ultrasound ye- screening kwiiveki ezingama-20 , ekubeni ngokudibanisa kwe-VS nezinye iintsilelo zentliziyo ezingavumelani nobomi, umfazi unokucetyiswa ukuba angaphazamise ukukhulelwa. Kwaye kunye ne-VSD eyinqanaba elifanelekileyo lokulawulwa kokubeleka kunye nokunyanga kwithuba lokugqibela emva kwe-80% yabantwana banethuba lokuphila.

I-DMF ye-fetus - unyango

Nge-VSW, uxinzelelo lwakhiwa kwisangqa esincinci sokujikeleza, kwaye ixesha apho umsebenzi oza kwenziwa khona lixhomekeke ngokuthe ngqo kwixabiso lesiphene.

Usebenziso lweVSD unyango. Ukuba isiphene se-septum sikhulu, kufuneka kusebenze kwiinyanga ezintathu zokuqala emva kokubeletha. Ngeempembelelo ezilinganayo kunye nokuxinwa kweengcinezelo kwisigxina esincinci segazi, umntwana usetyenziselwa ukufikelela kwiinyanga ezi-6 emva kokuzalwa, enomyinge ngokunyuka okuncinci kwiphepha elifanelekileyo kunye neephene ezincinane - unyaka. Ezinye iziphoso ezincinci kweli xesha zivaliwe ngokwazo.
