He aha ka nuchal translucency?
Aia ka Nuchal translucency, e like me ka inoa, aia ma ka ʻāʻī o ka pēpē. Ma muli o kahi kaʻawale liʻiliʻi ma waena o ka ʻili a me ke kuamoʻo a pili i kahi i kapa ʻia ʻo anechoic zone (ʻo ia hoʻi ka mea ʻaʻole e hoʻihoʻi i kahi leo i ka wā o ka hoʻokolokolo). Loa'a ka translucency nuchal a pau i ka trimester mua, akā e pau ka translucency nuchal. E nānā i ka translucency nuchal.
No ke aha e ana i ka translucency nuch?
ʻO ke ana ʻana o ka translucency nuchal ka hana mua i ka nānā ʻana i nā maʻi chromosomal, a no ka trisomy 21. Hoʻohana ʻia ia e ʻike i nā mea ʻino i ke kahe lymphatic a me kekahi mau maʻi puʻuwai. Ke hōʻike ke ana i kahi pilikia, manaʻo nā kauka he "hōʻailona kelepona", kahi kumu no ka noiʻi hou aku.
I ka manawa hea ke ana ana?
Pono e ana ka nuchal translucency i ka wā o ka ultrasound mua o ka hāpai ʻana, ʻo ia hoʻi ma waena o 11 a me 14 wiki o ka hāpai ʻana. Pono e hana ʻia ka hoʻokolokolo ʻana i kēia manawa, no ka mea ma hope o ʻekolu mahina, nalowale ka translucency nuchal.
Nuchal translucency: pehea e helu ʻia ai nā pilikia?
A hiki i 3 mm mānoanoa, manaʻo ʻia ka translucency nuchal. Maluna, helu ʻia nā pilikia ma muli o ka makahiki makuahine a me ka manawa o ka hāpai ʻana. ʻO ka nui o ka wahine, ʻoi aku ka nui o nā pilikia. Ma ka lima ʻē aʻe, ʻoi aku ka holomua o ka hāpai ʻana i ka manawa o ke ana ʻana, ʻoi aku ka nui o ka hoʻemi ʻia: inā e ana ka ʻāʻī i 4 mm i nā wiki 14, ʻoi aku ka haʻahaʻa o nā pilikia ma mua o ke ana ʻia ʻo 4 mm i 11 mau pule.
ʻO ke ana translucency Nuchal: he 100% hilinaʻi?
Hiki i ke ana translucency nuchal ke ʻike ma mua o 80% o nā hihia o ka trisomy 21, akā ʻo 5% o nā hihia o nā ʻāʻī mānoanoa loa i lilo i mea. nā mea maikaʻi ʻole wahaheʻe.
Pono kēia hoʻokolohua i nā ʻenehana ana pololei loa. I ka wā o ka ultrasound, hiki ke hōʻemi ʻia ka maikaʻi o ka hopena, no ka laʻana ma kahi kūlana maikaʻi ʻole o ka pēpē.
Anana translucency Nuchal: he aha ka mea e hiki mai ana?
I ka pau ʻana o kēia hoʻokolohua, hāʻawi ʻia kahi hoʻāʻo koko i kapa ʻia ʻo assay of serum markers i nā wahine hāpai āpau. ʻO nā hopena o kēia loiloi, i hui pū ʻia me ka makahiki makuahine a me ke ana ʻana o ka translucency nuchal, hiki ke loiloi i kahi pilikia o ka trisomy 21. Inā kiʻekiʻe kēia, e hāʻawi ke kauka i ka makuahine i nā koho he nui: ʻo TGNI , non-invasive prenatal. ka nānā ʻana (he laʻana koko mai ka makuahine) a i ʻole ka hana ʻana i kahi biopsy trophoblast a i ʻole amniocentesis, ʻoi aku ka invasive…. ʻO kēia mau hoʻāʻo hope ʻelua e hiki ai ke nānā i ke karyotype o ka pēpē a ʻike pono inā he maʻi chromosomal kona. ʻO ka pilikia o ka hāʻule ʻana he 0,1% no ka mua a me 0,5% no ka lua. A i ʻole, e ʻōlelo ʻia nā ultrasounds cardiac a morphological.
