Patient's question:
15 weeks + 5 days of prenatal checkup encountered issues, NF 4.9mm. The doctor said to wait for the Down syndrome results to make a judgment. I heard that the higher the NF value, the more dangerous it is. What should I do now as it is elevated? Here are the details:Biparietal diameter (BPD): 31mm - 15w6d
Crown-rump length (CRL): 119mm - 15w6d
Abdominal circumference (AC): 95mm - 15w5d
Femur length (FL): 19mm - 15w6d
Spinal position: Left anterior
Placental maximum thickness: 23mm
Maximum amniotic fluid depth: 31mm
Lower edge distance from cervical os: 16mm
Fetal heart rate and fetal movement are present.
NF: 4.9mm
I spent 200 yuan on the consultation fee, but the doctor didn’t explain anything clearly, just said to wait for the Down syndrome results.
Doctor's answer:
Analysis of the condition: NF refers to the thickness of the skin and soft tissues behind the fetal neck at 15 weeks to 20 weeks of gestation. The normal value is at 16 to 18 weeks of pregnancy.Recommendation: Additionally, if the measurement is greater than 6 mm and the chromosomes are normal, the likelihood of other malformations (to beed with color Doppler ultrasound) is significantly higher compared to those less than 6 mm (malformations may not necessarily be accompanied by chromosomal abnormalities). It is recommended to undergo amniocentesis to rule out the possibility of malformations.
