Patient's question:
I had a check-up 2 days ago before the 20th week of pregnancy. The results said the NF value was high, about 6.8mm. All other developments are normal. Is this a big problem? I am now 20 weeks and 5 days. Two weeks later, I am scheduled for a follow-up. Should I have an amniocentesis now or wait until after the follow-up? I am eagerly awaiting an answer. Thank you. Also, the check-up results mentioned an irregular heartbeat.Doctor's answer:
Such an NF cannot be greater than 6mm. If it is greater than 6mm, the possibility of chromosomal abnormalities is significantly higher compared to those less than 6mm (chromosomal abnormalities do not necessarily lead to deformities, but they may affect postnatal growth and development, life, and offspring). At the same time, individuals with an NF greater than 6mm have a significantly higher likelihood of other deformities (detected via color Doppler ultrasound) even if their chromosomes are normal (deformities do not necessarily indicate chromosomal abnormalities).
