Nema smisla posle 13+nesto, nisam sigurna za broj.nikailuka prvotno napisa
Ta tecnost koja cini nuhalni nabor je razvojna faza, i kasnije se povuce.
Ima veze sa razvojem limfnog sistema.
Evo sa wikipedije, cisto kao note, a ako te zanima, proguglaj malo, ima textova, ali kad sam trazila nisam nista sacuvala:
The translucent area measured (the nuchal translucency) is only usable to measure between 10 and 14 weeks’ gestation, when the fetal lymphatic system is developing and the peripheral resistance of the placenta is high. After 14 weeks the lymphatic system is likely to have developed sufficiently to drain away any excess fluid, and changes to the placental circulation will result in a drop in peripheral resistance. So after this time any abnormalities causing fluid accumulation may seem to correct themselves and can thus go undetected by making a nuchal scan.
