Nucal translucency: he aha ia, he aha ia no a pehea e hana ai

Anter

• No ke aha ka hōʻike
• Pehea e hana ai a me nā helu kuhi
• I ka manawa e hana ai i ka translucency nuchal

ʻO ka translucency nuchal kahi hōʻike, hana ʻia i ka manawa o ka ultrasound, i hoʻohana ʻia e ana i ka nui o ka wai ma ka ʻāpana o ka ʻāʻī o ka fetus a pono e hoʻokō ʻia ma waena o ka 11th a me ka 14th wiki o ka hānau ʻana. Hoʻohana ʻia kēia hoʻokolohua e hoʻomaulia i ka makaʻu o ka pēpē i loaʻa i kahi malformation a i ʻole syndrome, e like me Down Syndrome.

Ke loaʻa nā malformations a i ʻole nā ​​maʻi genetical, hānai ka fetus e hōʻiliʻili i ka wai i ka piko o ka ʻāʻī, no laila inā hoʻonui ʻia ke ana o ka translucency nuchal, ma luna o 2.5 mm, ʻo ia hoʻi he hoʻololi paha i kāna ulu.

No ke aha ka hōʻike

ʻO ke ana ʻana o ka translucency nuchal ʻaʻole ia e hōʻoia i ka maʻi a me ka malformation paha o ka pēpē, akā hōʻike ia inā ua hoʻonui ʻia ka makaʻu o ka pēpē i ka loaʻa ʻana o kēia mau loli.

Inā hoʻololi ʻia ke kumukūʻai hōʻoia, e noi ka mea hānau i nā hoʻokolohua ʻē aʻe e like me amniocentesis, no ka laʻana, e hōʻoia a ʻaʻole paha ka hōʻailona.

Pehea e hana ai a me nā helu kuhi

Hana ʻia ka translucency nuchal i kekahi o nā ultrasound kani mua, a i kēia manawa, ana ke kauka i ka nui a me ka nui o ka wai ma ka ʻāpana ma hope o ka ʻāʻī o ka pēpē, me ka ʻole o kekahi kaʻina hana kūikawā ʻē aʻe.

ʻO nā waiwai translucency nuchal hiki ke:

• Maʻamau: ma lalo o 2.5 mm
• Hoʻololi ʻia: like a i ʻole ʻoi aku ma mua o 2.5 mm

ʻO ka ninaninau ʻana me ka hoʻonui ʻia o ka waiwai ʻaʻole ia e hōʻoia i ka ʻeha ʻana o ka pēpē mai nā hoʻololi ʻana, akā hōʻike ia aia he ʻoi aku ka nui o ka makaʻu a, no laila, e noi ana ka mea hānau i nā hōʻike ʻē aʻe, e like me amniocentesis, ka mea e lawe i kahi laʻana o ka wai amniotic, aiʻole cordocentesis, kahi e loiloi ai i kahi laʻana koko. E aʻo hou e pili ana i ka hana ʻia ʻana o ka amniocentesis a i ʻole cordocentesis.

Inā i ka manawa o ka ultrasonography aia pū ka nele o ka iwi ihal, hoʻonui ka makaʻu o kekahi malformation ʻoi aku, ʻoiai ʻaʻole ka iwi āpau i nā hihia o nā syndrome.

Ma waho aʻe o ka translucency nuchal, ka makahiki o ka makuahine a me ka mōʻaukala o nā loli chromosomal a i ʻole nā ​​maʻi genetical he mea nui e helu i ka pilikia o ka pēpē e loaʻa i kekahi o kēia mau loli.

I ka manawa e hana ai i ka translucency nuchal

Pono e hana i kēia hoʻokolohua ma waena o ka 11th a i ka 14th wiki o ka hānau ʻana, ʻoiai ke manawa ka fetus ma waena o 45 a me 84 mm ka lōʻihi a hiki ke hiki ke helu i ke ana translucency nuchal.

Hiki ke ʻike ʻia me ka ultrasound morphological o ka trimester mua, no ka mea, ma waho o ke ana o ka ʻāʻī o ka pēpē, kōkua pū ia e ʻike i nā malformations i nā iwi, nā puʻuwai a me nā kīʻaha koko.

E aʻo e pili ana i nā hoʻokolohua ʻē aʻe e pono ai i ka trimester mua o ka hāpai keiki.
