Ngokusho kwemiphumela yokuhlolwa kwe-ultrasound eyenziwa ngesikhathi sokusana, udokotela angenza ingane ihlolwe ngokuthi "iwindi elivulekile lewindi". Kuyinto engalungile inhliziyo lapho ukukhulumisana phakathi kwe-atria kuyaqhubeka, okuyisinye sezigaba zokuthuthukiswa kwe-intrauterine. Ukuvalwa komzimba kwefasitela le-oval ngokusebenzisa i-valve enganeni esanda kuzalwa kwenzeka ngesikhathi sokuzalwa, lapho kuphefumula okokuqala. Kodwa-ke, iwindi le-oval lingakwazi ukuhlala livulekile kuze kube usuku lwesihlanu lokuphila kwengane, futhi kubhekwe njengesijwayelekile (ezingaphezu kuka-40% zezingane ezinefasitela elivulekile evikini lokuqala lokuphila). Uma iqhubeka ivulekile, lapho ingane ikhula, ingazivala engxenyeni yesibili yonyaka wokuqala wokuphila wengane. Kodwa lokhu akukwenzeka njalo.
Iyiphi iwindi eliyindilinga elivulekile elivulekile ezinganeni?
Kukhona amaphuzu amabili okubukwayo enkingeni yokuba khona kwewindi levolumu enganeni esanda kuzalwa. Abanye odokotela bacabanga ukuthi lokhu kuyinto evamile yentuthuko, engathinti ukuqhubeka komuntu. Abanye banombono wokuthi ukukhubazeka okunjalo kwenhliziyo kungalimaza ukuphila komuntu futhi kubambe iqhaza ekuthuthukiseni ukuqubuzana okuxilisayo, izimo ze-hypocemic.
Izizathu zewindi elivulekile lewindi
Ukukhubazeka okunjalo okuvame ukutholakala kubantwana abasanda kuzalwa . Njengoba bezelwe ngaphambi kwaleso sikhathi, uhlelo lwezinhliziyo aluzange lukwazi ukuqedela ukuthuthukiswa kwalo kubantwana, ngenxa yalokho ukukhubazeka kwentuthuko yenhliziyo kuphawulwe ngesimo sewindi evulekile.
Futhi, iwindi le-oval lingase libe yinkinga yokuzalwa yangasese eyakhiwe esiteji sokuthuthukiswa kwe-intrauterine ngaphansi kwethonya lezici ze-pathogenic ngesikhathi sokukhulelwa kowesifazane:
- ukubhema;
- utshwala;
- izidakamizwa;
- phenylketonuria, isifo sikashukela somama;
- Ukusetshenziswa kwemithi kuqhathaniswa ngesikhathi sokukhulelwa nokubeletha.
Vula ifasitela le-oval ezinsana: izimpawu
Endabeni yokuxilongwa, njengombuso, azikho izimpawu zefasitela elivulekile le-oval, kuyinkinga enkulu ukusola ukuthi kukhona ukuxilongwa okunjalo ngaphandle. Kodwa-ke, kunezinombolo eziningi zezici ezingase zibonise ukuthi kungenzeka ukuthi kukhona ukukhubazeka kwenhliziyo enjalo:
- Ngesikhathi sokukhwehlela, ukukhala, noma ukuzikhandla ngokomzimba, unxantathu ongenawobubi uba ngumbala okwesibhakabhaka kumntwana;
- ukwanda kwenhliziyo ngesikhathi sokudla;
- ukudla okumbi;
- inzuzo enganele ngokwesisindo;
- izifo ezivame ukuguga nezifo;
- ukunciphisa ijubane lokuthuthukiswa ngokomzimba;
- ukulahleka kokungazi lutho.
Vula ifasitela elivundlile: ukwelashwa
Ukuze ukhethe ukwelashwa okungcono kakhulu kwesifo senhliziyo, kubalulekile ukuqapha ingane ngokuzama ukuhlolwa kwe-echo cardiogram ukulandelela usayizi wewindi le-oval. Uma kukhona ukuthambekela kokunciphisa usayizi, ngakho-ke, njengoba umthetho, akukho ukwelashwa okukhethekile okudingekayo. Kodwa-ke, uma ukuguqulwa ngosayizi kuphawulwa, iwindi elivulekile lewindi ludinga
Uma ingane esanda kuzalwa inezinye izinkinga ze-cardiovascular (isibonelo, i-aneurysm ye-septum ye-interatrial), khona-ke ingozi yezinkinga kungenzeka. Kulesi simo, ukuhlinzwa ukuvala iwindi le-oval lenzelwe ukuthuthukisa inhliziyo.
