Vala iwindi elingu-oval kwiintsana

Ngokweziphumo ze-ultrasound diagnostics ezenziwa ngethuba lokusana, ugqirha unokufaka umntwana ukuba abe "iwindow evulekileyo yewindi". Yisisiphako senhliziyo apho ukukhulumisana phakathi kwe-atria kuyaqhubeka, yenye yeyimiqathango yokuphuhliswa kwe-intrauterine. Ukuvalwa komzimba kwefestile ye-oval ngokusebenzisa i-valve emntwaneni osandula kuzalwa kwenzeka ngexesha lokuzalwa, xa lenza umoya wokuqala wokuzimela. Nangona kunjalo, iwindi le-oval lingakwazi ukuhlala livulekile kuze kube ngumhla wesihlanu wobomi bomntwana, kwaye ikwajongwa njengesiqhelo (ngaphezu kwe-40% yabantwana banes window evulekileyo yevalo kwikota yokuqala yobomi). Ukuba iyaqhubeka ivulekile, njengoko umntwana ekhula, iyakwazi ukuzivala kwisiqingatha sesibini somntwana wokuqala wokuphila komntwana. Kodwa oku akusoloko kwenzeka.

Iyiphi iwindi evulekileyo yefestile evulekile kubantwana?

Kukho iingcamango ezimbini kwiingxaki zobuninzi befestile ye-ovari kumntwana osandula. Abanye oogqirha bakubheka oku kusemgangathweni yophuhliso, olungathinteli ubomi obungakumbi bomntu. Abanye banombono wokuba eso siphene sentliziyo singasongela ubomi bomntu kwaye senze igalelo ekuphuhliseni ukuxhamla, ukunyaniseka kweemeko.

Izizathu ze window evulekile

Esi siphene siphuhliso sisoloko sifumaneka kwiintsana ezisanda kuzalwa . Emva kokuzalwa ngaphambi kwekota, intliziyo yesimo ayizange ikwazi ukugqibezela ukuphuhliswa kwayo kubantwana, ngenxa yentsholongwane yokuphuhliswa kwentliziyo ibonakala ngefowuni evulekile.

Kwakhona, iwindi le-oval ingaba yintsholongwane engumntwana owenziwe kwinqanaba lokuphuhliswa kwe-intrauterine ngaphantsi kwefuthe lezinto ezinama-pathogenic ngexesha lokukhulelwa komfazi:

• ukutshaya;
• utywala;
• machiza;
• phenylketonuria, isifo sikashukela sikamama;
• Ukusetyenziswa kwamachiza angqiniswanga ngexesha lokukhulelwa nokubeletha.

Vula ifowuni ye-oval kwiintsana ezisandul 'ukuzalwa: iimpawu

Kwimeko yokuxilongwa, njengomthetho, akukho zibonakaliso zefestile evulekileyo, kuyinkathazo enkulu kakhulu ukukrokra ukuba kukho ukuxilongwa kwangaphandle. Nangona kunjalo, kukho iinkalo ezininzi ezinokuthi zibonise ukubonakala kweso siphene sentliziyo:

• Ngethuba lokukhwehlela, ukukhala, okanye ukunyanzelisa umzimba, unxantathu obuthathekayo uba ngumbala okwesibhakabhaka kumntwana;
• ukwanda kwenani lentliziyo ngexesha lokutya;
• ngxamele ukutya;
• inzuzo engeneliyo;
• izifo ze-catarrha kunye nezifo ezivuthayo;
• ukunciphisa ukuhamba komzimba;
• ukulahleka kokungazi kakuhle.

Vala iwindi yewindi: unyango

Ukukhetha unyango olungcono kwisifo senhliziyo, kuyimfuneko ukubeka iliso kwintsana ngamandla kunye nokuhlolwa kwe-cardiogram ukulandelela ubungakanani befestile ye-oval. Ukuba kukho ukuthambekela kokunciphisa ubukhulu, ngoko, njengommiselo, akukho nonyango olulodwa olufunekayo. Nangona kunjalo, ukuba utshintsho kwisayizi luyabonwa, ke i window efakwe kwi-window evulekile idinga ukungenelela okutyathwayo: i-transcatheter yokuvalwa yokusebenza isebenza ngokusetyenziswa kwesixhobo esikhethekileyo. Ukuba umsebenzi awukwenziwanga ngexesha, umntwana usenokuphuma kwegazi ukusuka kwelinye i-atrium ukuya kwenye. Kwixesha elizayo, xa i-septum yefestile ye-oval ingabonakaliswa, i-emboli (i-embolism e-paradoxical) iyondla i-cortex ye-cerebral ingena kwiinqanawa. Emva koko, iingxaki zebhakteria zenzeka.

Ukuba umntwana osandul 'uzalwa uneminye imiba enesifo senhliziyo (umzekelo, i-aneurysm ye-septum ye-interumrial), ke ingozi yokuxinzelela ingakumbi. Kule meko, utyando lokuvala iwindi le-oval lenzelwe ukuphucula intliziyo.
