Ukuhlolwa kwe-Nuchal translucency

Ukuhlolwa kwe-nuchal translucency kukala ubukhulu be-nuchal fold. Le yindawo yezicubu ngemuva kwentamo yengane engakazalwa. Ukukala lobu bukhulu kusiza ukuhlola ubungozi be-Down syndrome nezinye izinkinga zofuzo enganeni.

Umhlinzeki wakho wezokunakekelwa kwempilo usebenzisa i-ultrasound yesisu (hhayi sowesifazane sangasese) ukukala isibambo se-nuchal. Zonke izingane ezingakazalwa zinoketshezi oluthile ngemuva kwentamo yazo. Enganeni ene-Down syndrome noma ezinye izifo zofuzo, kunoketshezi oluningi kunokujwayelekile. Lokhu kwenza isikhala sibonakale sijiyile.

Ukuhlolwa kwegazi kukamama nakho kuyenziwa. Ngokubambisana, lezi zivivinyo ezimbili zizotshela ukuthi ngabe ingane ingaba ne-Down syndrome noma esinye isifo sofuzo.

Ukuba nesinye esigcwele kuzonikeza isithombe esihle kakhulu se-ultrasound. Ungacelwa ukuthi uphuze izingilazi ezimbili kuya kwezi-3 zoketshezi ehoreni ngaphambi kovivinyo. Ungachami ngaphambi kwe-ultrasound yakho.

Ungase ube nokungahambi kahle ekucindezelweni kwesisu sakho ngesikhathi se-ultrasound. Ijeli elisetshenziswe ngesikhathi sokuhlolwa lingazizwa libanda kancane futhi limanzi. Ngeke uzwe amagagasi e-ultrasound.

Umhlinzeki wakho angaluleka lesi sivivinyo ukuze kuhlolwe ingane yakho i-Down syndrome. Abesifazane abaningi abakhulelwe banquma ukwenza lokhu kuhlolwa.

I-Nuchal translucency ivame ukwenziwa phakathi kweviki le-11 nele-14 lokukhulelwa. Kungenziwa ekuqaleni kokukhulelwa kune-amniocentesis. Lokhu okunye ukuhlolwa okuhlola ukukhubazeka kokuzalwa.

Inani elijwayelekile loketshezi ngemuva kwentamo ngesikhathi se-ultrasound kusho ukuthi akunakwenzeka ukuthi ingane yakho ine-Down syndrome noma esinye isifo sofuzo.

Isilinganiso se-Nuchal translucency siyanda ngeminyaka yokukhulelwa. Lesi yisikhathi esiphakathi kokukhulelwa nokuzalwa. Ukuphakama kwesilinganiso kuqhathaniswa nezingane ezineminyaka efanayo yokukhulelwa, ingozi iba ngaphezulu kwezifo ezithile zofuzo.

Izilinganiso ezingezansi zibhekwa njengengozi ephansi yokuphazamiseka kofuzo:

• Emasontweni ayi-11 - kufika ku-2 mm
• Emasontweni ayi-13, izinsuku eziyisithupha - kufika ku-2.8 mm

Uketshezi oluningi kunokujwayelekile emhlane entanyeni kusho ukuthi kunengozi enkulu ye-Down syndrome, i-trisomy 18, i-trisomy 13, i-Turner syndrome, noma isifo senhliziyo esizalwe naso. Kepha akutsheli ngokuqinisekile ukuthi umntwana une-Down syndrome noma esinye isifo sofuzo.

Uma umphumela ungavamile, ezinye izivivinyo zingenziwa. Isikhathi esiningi, okunye ukuhlolwa okwenziwe yi-amniocentesis.

Azikho izingozi ezaziwayo ezivela ku-ultrasound.
