Nuchal translucency: zoopsa zimawerengedwa bwanji?
Kufikira 3 mm wandiweyani, nuchal translucency imatengedwa ngati yachilendo. Pamwamba, zoopsa zimawerengedwa potengera zaka za amayi komanso nthawi yomwe ali ndi pakati. Mkazi akamakula, m'pamenenso ngozi zake zimakhala zazikulu. Kumbali ina, pamene mimba imakhala yopita patsogolo kwambiri panthawi ya kuyeza, chiopsezocho chimachepetsedwa: ngati khosi likuyesa 4 mm pa masabata a 14, zoopsa zimakhala zochepa kusiyana ndi 4 mm pa masabata a 11.

Ngati izi zili pamwamba, dokotala adzapereka mayiyo njira zingapo: mwina TGNI , osasokoneza prenatal. kuyezetsa (kuyesa magazi kuchokera kwa amayi) kapena kupanga trophoblast biopsy kapena amniocentesis, movutikira…. Mayesero awiri omalizirawa amapangitsa kuti athe kusanthula karyotype ya mwana wosabadwayo ndikudziwa ngati ali ndi matenda a chromosomal. Chiwopsezo cha kupititsa padera kukhala 0,1% koyamba ndi 0,5% kwachiwiri. Apo ayi, mtima ndi morphological ultrasounds adzalimbikitsidwa.
