Kusintha kwa Nuchal: ndi chiyani, ndi chiyani komanso momwe zimachitikira

Zamkati

• Kodi mayeso ndi ati
• Momwe zimachitikira ndi kutengera mfundo
• Nthawi yochita kusintha kwa nuchal

Nuchal translucency ndi mayeso, omwe amachitika nthawi ya ultrasound, yomwe imagwiritsidwa ntchito kuyeza kuchuluka kwa madzi m'chigawo cha khosi la mwana wosabadwa ndipo akuyenera kuchitika pakati pa sabata la 11 ndi 14 la kubereka. Mayesowa amagwiritsidwa ntchito kuwerengera chiopsezo cha mwana yemwe ali ndi vuto kapena matenda, monga Down syndrome.

Pakakhala zovuta kapena matenda amtundu wa chiberekero, mwana wosabadwa amayamba kudziunjikira madzimadzi mu khosi, kotero ngati muyeso wa kusintha kwa nuchal ukuwonjezeka, kupitirira 2.5 mm, zikutanthauza kuti pangakhale kusintha pakukula kwake.

Kodi mayeso ndi ati

Kuyeza kwa kusintha kwa nuchal sikutsimikizira kuti mwana ali ndi matenda amtundu kapena vuto, koma zimawonetsa ngati mwana ali ndi chiopsezo chowonjezeka chosintha.

Mtengo woyeserera ukasinthidwa, dokotala wobereka amafunsira mayeso ena monga amniocentesis, mwachitsanzo, kuti atsimikizire kapena ayi.

Momwe zimachitikira ndi kutengera mfundo

Kusinthasintha kwa nuchal kumachitika panthawi imodzi yobereka ndipo, pakadali pano, adotolo amayesa kukula ndi kuchuluka kwa madzi omwe ali mdera la khosi la mwana, osafunikira njira ina iliyonse yapadera.

Makhalidwe a nuchal translucency atha kukhala:

• Zachibadwa: osakwana 2.5 mm
• Zasinthidwa: wofanana kapena wopitilira 2.5 mm

Kufufuza komwe kumawonjezera phindu sikutsimikizira kuti mwanayo ali ndi vuto lililonse, koma kukuwonetsa kuti pali chiopsezo chachikulu, chifukwa chake, woperekayo adzafunsa mayeso ena, monga amniocentesis, omwe amatenga madzi amniotic amadzimadzi, kapena cordocentesis, yomwe imayesa chingwe cha magazi. Phunzirani zambiri za momwe amniocentesis kapena cordocentesis amapangidwira.

Ngati nthawi ya ultrasonography kulibe kukhalapo kwa mafupa amphongo, chiopsezo chazovuta zina chimakulirakulira, popeza kuti mphuno yamphongo nthawi zambiri imakhalapo pakakhala ma syndromes.

Kuphatikiza pa kusandulika kwa nuchal, msinkhu wa amayi ndi mbiri ya banja yosintha chromosomal kapena matenda amtunduwu ndikofunikanso kuwerengera chiopsezo cha mwana kuti asinthe.

Nthawi yochita kusintha kwa nuchal

Kuyesaku kuyenera kuchitika pakati pa sabata la 11 mpaka la 14 la bere, monga nthawi yomwe mwana amakhala pakati pa 45 ndi 84 mm m'litali ndipo ndizotheka kuwerengera muyeso wa nuchal translucency.

Itha kudziwikanso ndi morphological ultrasound ya trimester yoyamba, chifukwa, kuphatikiza pakuyeza kwa khosi la mwana, zimathandizanso kuzindikira zolakwika m'mafupa, mtima ndi mitsempha yamagazi.

Phunzirani za mayeso ena omwe amafunikira mu trimester yoyamba yapakati.
