Litaba

Nuchal translucency ke tlhatlhobo, e etsoang nakong ea ultrasound, e sebelisetsoang ho lekanya palo ea mokelikeli tikolohong ea molala oa lesea le lokelang ho etsoa lipakeng tsa beke ea 11 le ea 14 ea bokhachane. Teko ena e sebelisetsoa ho bala kotsi ea lesea le nang le malformation kapa syndrome, joalo ka Down syndrome.

Ha malformations kapa mafu a liphatsa tsa lefutso a le teng, lesea le tloaetse ho bokella mokelikeli nape ea molala, ka hona haeba tekanyo ea translucency ea nuchal e eketsehile, kaholimo ho 2,5 mm, ho bolela hore ho ka ba le phetoho kholisong ea eona.

Tlhahlobo ke efe bakeng sa

Tekanyo ea translucency ea nuchal ha e netefatse hore lesea le na le lefu la lefutso kapa ho senyeha ha maikutlo, empa e bonts'a hore na ngoana o na le kotsi e kholo ea ho ba le liphetoho tsena kapa che.

Haeba boleng ba tlhahlobo bo fetotsoe, ngaka ea pelehi e tla kopa liteko tse ling tse kang amniocentesis, mohlala, ho netefatsa kapa ho se hlahlojoe.


E etsoa joang le litekanyetso tsa boits'oaro

Translucency ea nuchal e etsoa nakong e 'ngoe ea li-ultrasound tsa bakhachane mme, motsotsong ona, ngaka e lekanya boholo le palo ea mokelikeli o sebakeng se kamora molala oa ngoana, ntle le tlhoko ea ts'ebetso e ngoe e ikhethang.

Litekanyetso tsa nuchal translucency e ka ba:

  • E tloaelehileng: ka tlase ho 2,5 mm
  • E fetotsoe: lekana kapa hofeta 2.5 mm

Tlhatlhobo e nang le boleng bo eketsehileng ha e fane ka tiiso ea hore lesea le na le phetoho efe kapa efe, empa e bonts'a hore ho na le kotsi e kholo mme, ka hona, ngaka ea pelehi e tla kopa liteko tse ling, joalo ka amniocentesis, e nkang sampole ea mokelikeli oa amniotic, kapa cordocentesis, e lekolang sampole ea mali. Ithute ho eketsehileng ka hore na amniocentesis kapa cordocentesis li entsoe joang.

Haeba nakong ea ultrasonography ho boetse ho na le ho se be teng ha masapo a nko, kotsi ea ho senyeha hampe e eketseha ho feta, hobane lesapo la nko hangata ha le eo maemong a syndromes.


Ntle le phetoho ea nuchal, nalane ea mme le nalane ea lelapa ea liphetoho tsa chromosomal kapa maloetse a liphatsa tsa lefutso le tsona li bohlokoa ho bala kotsi ea ngoana ea ho ba le e 'ngoe ea liphetoho tsena.

U lokela ho etsa translucency ea nuchal neng

Teko ena e lokela ho etsoa lipakeng tsa beke ea 11 ho isa ho ea 14 ea bokhachane, joalo ka ha lesea le le pakeng tsa 45 le 84 mm ka bolelele mme ho a khonahala ho bala tekanyo ea nuchal translucency.

E ka tsejoa hape ka morphological ultrasound ea trimester ea pele, hobane, ntle le ho lekanya molala oa ngoana, e boetse e thusa ho khetholla ho senyeha ha masapo, pelo le methapo ea mali.

Ithute ka liteko tse ling tse hlokahalang khoeling ea pele ea bokhachane.
