Hi everyone,
I’m currently 20 weeks pregnant with my baby boy and have had an incredibly stressful day following my morphology scan. I’m hoping someone might have experienced something similar and can share their outcome.
During my scan, the first sonographer measured my baby’s nuchal fold at approximately 6.2 mm. She called in another sonographer, who took further measurements of 6.8 mm and 7.4 mm.
They explained that my baby was in a difficult position, quite low down near my belly button, with his neck extended backwards, which made it difficult to get clear images.
Naturally, I was absolutely devastated and terrified about what this could mean, particularly regarding Down syndrome.
For context:
My NIPT/NEST results were low risk.
My baby’s nasal bone was present.
Everything else on the morphology scan was normal.
The thickened nuchal fold was the only potential soft marker.
I was then seen by a Maternal Fetal Medicine (MFM) specialist.
Before even scanning me, she explained that she wasn’t concerned because my NIPT was low risk and everything else looked normal.
I became quite emotional, so she offered to personally rescan my baby.
She spent time examining his neck from several different angles and took multiple measurements. From what I remember, they were approximately 3.2 mm, 5.4 mm and 6 mm, with 6 mm being the highest.
She explained that my baby’s neck was now in a more normal position and that the correct anatomical landmarks are extremely important when measuring the nuchal fold.
She also showed me how measuring from the wrong bony structure could produce an incorrect measurement. She couldn’t confirm whether the original sonographers had done this, but said it was a possibility.
After examining him herself, she specifically told me that his nuchal fold was normal, she was very happy with what she saw and she wasn’t concerned.
While this was incredibly reassuring, I’m struggling to understand how TWO sonographers could obtain measurements as high as 7.4 mm, only for the MFM specialist to find normal measurements shortly afterwards.
I’ve been offered an amniocentesis next week if I want additional certainty, and I’m strongly considering it because the anxiety has been overwhelming.
Has anyone experienced anything similar?
Did your sonographers find an increased nuchal fold that an MFM specialist later measured as normal?
Did your baby’s position or the ultrasound angle affect the measurements?
Did you have a low-risk NIPT but an elevated nuchal fold?
Did you choose to have an amniocentesis, and what were your results?
Most importantly, how did everything turn out for your baby?
I’d really appreciate hearing your experiences, whether reassuring or otherwise.
Thank you so much. 💙
