Ukuhlolwa kokubeletha

Namuhla wonke umuntu wesifazane okhulelwe kufanele ibhekane Ukuhlolwa kokubeletha. Lolu cwaningo ikhomba abesifazane nge ingozi eliphezulu uma ingane chromosomal kwezinso, ngokuyinhloko kuba Down Syndrome. Kubalulekile ukuqonda ukuthi imiphumela yalolu ukuhlaziywa - akuyona uphethwe esichazayo.

Abesifazane basengozini isidingo iphumelele ekuhlolweni ezengeziwe. Kulokhu, ukwenza i amniocentesis noma chorionic villus izibonelo zalokho. Nokho, qaphela ukuthi ngezinye izikhathi lezi manipulations kuholele isisu.

Ngokuvamile, ukuhlolwa ngaphambi kokuba umuntu azalwe, kunengqondo ukwenza kuphela labo besifazane usuqiniseka ukuthi uzozala ingane ngeke nge chromosomal kwezinso. Awokuthi bakulungele zokukhwabanisa eziyingozi, futhi isiqinisekiso uphethwe - sokuqeda ukukhulelwa. Uma kungenjalo, khona-ke isiguli nje okulahlwayo imali yakho.

Kokubeletha Ukuhlolwa senyanga 1 siqukethe ultrasound futhi ekunqumeni izinga igazi izimpawu ezithile. Ucwaningo eyenziwa nge-10 kuya 13 ngesonto. Okokuqala, ultrasound scan, lapho udokotela ehlola isithelo khona pathologies futhi alinganise Ubukhulu kudingekile ukubala ingozi.

Desirably ngosuku olulandelayo ukuba unikele ngegazi ukuze PAPP-A no khulula β-hCG. Uhlaziyo wenziwa esiswini esingenalutho ekuseni. On US kanye nemiphumela yokuhlolwa ezimbili ibalwa ingozi ukuthi syndromes Edwards futhi Down lapho i-fetus.

Kokubeletha Ukuhlolwa kwamakhemikhali Kwenziwa futhi senyanga 2nd. isikhathi ezinconyiwe - kusuka 16 kuya 18 ngesonto. Phakathi nale nkathi Igazi liyakuba estriol khulula, abezindaba ze-AFP, hCG Imininingwane noma khulula β-hCG. Ngu ngalezi zinkomba kubalwa ingozi yokuba kwemizwa tube ukukhubazeka, Down Syndrome ku-fetus futhi Edwards.

Kufanele kuqashelwe ukuthi ngisho noma owesifazane yokuthi mincane, namanje akusho ngakususi ukuzalwa komntwana nge egunjini lokuhlolwa kwezifo. Vele kuleli cala, ematfuba incane kakhulu, futhi dengwane.

Ezinye izici kunakwe kulesi sibalo ingozi. Lezi zihlanganisa IVF, ukubhema, isifo sikashukela, uhlanga, isisindo, imithi, ubudala, khona ukukhulelwa nge kwezinso zofuzo. Kufanele kuqashelwe ukuthi amadala owesifazane, ayanda amathuba chromosomal kwezinso e ingane. Ukuze yi lwamukeleke, kubalulekile ukwazi elithi ngqo.

Imiphumela iba yinhlanganisela yokukhandleka ifomu ngokuvamile akuyona inani eliphelele index, okuyinto incike ohlelweni ukuhlolwa, futhi umama (kaningi value isilinganiso ngaleso sikhathi esifanayo). Ubukhulu bayo kumele kube kusuka 0.5 kuya 2. sokukhulelwa evamile sibalo ezibucayi kuyinto 2.5, futhi uma amaningi - 3.5.

Uma isiguli uqhutshwa skinning kokubeletha, ukuphambuka kusuka kuyinsakavukela izinkomba ngabanye ke kungenziwa esolwa pathologies ezithile. Ngakho, ACE anda nephritic syndrome, tetralogy of Fallot, iphimbo, ukukhubazeka kwesikhumba, udonga besisu futhi neural tube.

Uma ngemuva ukubaluleka kwalo ongaphakeme anda hCG, kungenzeka ukuba usola i-Down Syndrome. Ikakhulukazi kufanele kube isizathu sokukhathazeka uma iziguli ezineminyaka engaphezu kwengu-30, futhi kungakhathaliseki ukuthi ukukhulelwa eziningi ngaphambili.

Izinto eziyingozi ezingabangela i chromosomal kwezinso:

• ngisho ngemisebe umngane womshado ngaphambi nje ebamba isisu;
• izifo ezibangelwa amagciwane (toxoplasmosis, rubella, i-hepatitis);
• isicelo owesifazane anticancer izidakamizwa ngaphambi noma ngesikhathi sokukhulelwa;
• iziyaluyalu monogenic emkhayeni ngokushesha;
• 2 kwesisu kusaqalwa;
• umndeni bekulokhu umbungu noma ingane enamazinyo izifo chromosomal ;
• yobudala engaphezu kwengu-35.

Ngakho, kuyinto efiselekayo ukwenza ukuhlolwa ngaphambi kokuba umuntu azalwe bonke abesifazane abalindele umntwana. Nokho, kubalulekile ukuba baqonde ukuthi imiphumela - lokhu akukona uphethwe esichazayo, kodwa isizathu kudlule luhlolo eyingozi. Uma owesifazane ngeke ukuphazamisa sokukhulelwa at isiqinisekiso chromosomal kwezinso ku ingane ke akunandaba mqondo ukuba bahlolwe. Njengoba isisu into ngaphandle hhayi odokotela banganikeza, izindlela ukulungiswa yalesi sifo namuhla akuyona.
