Uvavanyo lweNuchal translucency

Uvavanyo lwe-nuchal translucency yokulinganisa ubungakanani be-nuchal fold ubukhulu. Lo ngummandla weethishu ngasemva kwentamo yosana olungekazalwa. Ukulinganisa obu bunzima kunceda ukuvavanya umngcipheko we-Down syndrome kunye nezinye iingxaki zofuzo kusana.

Umboneleli wakho wokhathalelo lwempilo usebenzisa isisu se-ultrasound (hayi esesiswini) ukulinganisa umhlathana. Zonke iintsana ezingekazalwa zinamanzi athile emva kwentamo. Kusana olune-Down syndrome okanye ezinye iingxaki zemfuza, kukho ulwelo oluninzi kunesiqhelo. Oku kwenza ukuba indawo ijongeke ngathi iyajiya.

Uvavanyo lwegazi lukamama nalo luyenziwa. Ngokudibeneyo, ezi mvavanyo zimbini ziya kuxela ukuba ngaba umntwana angaba ne-Down syndrome okanye esinye isifo semfuza.

Ukuba nesinyi esipheleleyo kuya kunika owona mfanekiso mhle we-ultrasound. Unokucelwa ukuba usele iiglasi ezi-2 ukuya kwezi-3 zolwelo kwiyure phambi kovavanyo. SUKUCHAMA ngaphambi kwe-ultrasound yakho.

Usenokungonwabi kwingcinezelo yesinyi sakho ngexesha le-ultrasound. Ijeli esetyenziswe ngexesha lovavanyo inokuziva ibanda kwaye imanzi. Awuyi kuva amaza e-ultrasound.

Umboneleli wakho unokucebisa olu vavanyo ukuba luscreen usana lwakho kwi-Down syndrome. Uninzi lwabasetyhini abakhulelweyo bagqiba ekubeni benze olu vavanyo.

Ukutshintsha kwe-Nuchal kuhlala kwenziwa phakathi kwiveki ye-11 neye-14 yokukhulelwa. Inokwenziwa kwangoko xa ukhulelwe kune-amniocenteis. Olu lolunye uvavanyo olukhangela iziphene zokuzalwa.

Inani eliqhelekileyo lolwelo emva kwentamo ngexesha le-ultrasound lithetha ukuba akunakulindeleka ukuba umntwana wakho abe ne-Down syndrome okanye esinye isifo semfuza.

Imilinganiselo ye-Nuchal translucency inyuka ngexesha lokukhulelwa. Eli lixesha eliphakathi kokukhulelwa nokuzalwa. Ukuphakama komlinganiso xa kuthelekiswa neentsana zobudala obufanayo, kokukhona umngcipheko ubakho kukuphazamiseka kwemfuza.

Imilinganiselo engezantsi ithathwa njengomngcipheko ophantsi wokuphazamiseka kwemfuzo:

• Kwiiveki ezili-11 ukuya kwi-2 mm
• Kwiiveki ezili-13, iintsuku ezi-6 ukuya kuthi ga kwi-2.8 mm

Okungakumbi kunesiqhelo emqolo entanyeni kuthetha ukuba kukho umngcipheko ophezulu we-Down syndrome, i-trisomy 18, i-trisomy 13, i-Turner syndrome, okanye isifo sentliziyo esibelekweni. Kodwa ayixeleli ngokuqinisekileyo ukuba umntwana une-Down syndrome okanye esinye isifo semfuza.

Ukuba iziphumo aziqhelekanga, olunye uvavanyo lunokwenziwa. Uninzi lwexesha, olunye uvavanyo olwenziwe yi-amniocenteis.

Akukho bungozi baziwayo kwi-ultrasound.
