High nuchal fold: if CVS comes back clear then what?

[Lilolilo123]

Hi all, I’ve been given 1:4 Down’s syndrome risk yesterday as the NT was 5.8 and there were also markers in my blood and I’m 39. Going for CVS tomorrow to know for certain. But I hear sometimes the CVS comes back clear - then what? If there are no chromosomal abnormalities, what causes such a massive NT? I guess what I’m asking is - has anyone here got abnormal NT results, then went on to have a clear CVS or amnio, and eventually gave birth to a healthy baby? My gut tells me with 5.8 there is almost no chance something is not wrong, but maybe there are some examples of miracles?

Hi there,
I'm sorry you're going through this stress, it's really the worst. My NT measurement was 3.7mm at 12 weeks. To answer your question, after we had the CVS come back clear, I was scheduled for an early anatomy scan at 16 weeks and a fetal echo to check the heart. I'm 28 weeks now and am having monthly growth ultrasounds. I'm in the U.S. so the process might be slightly different for you. I was told that structural defects, and heart problems in particular, are associated with increased nuchal measurements. And sometimes they just never find a cause at all. And for the record I have read several stories where NT measurements as high as yours have resolved and baby has been born healthy. Sending hugs and good vibes that everything works out OK!!

Thank you for the ray of hope @georgiablue2 and best of luck in your pregnancy!

I just got a call about my Harmony test and it’s 99% Down’s. CVS tomorrow should confirm that. I guess I was hoping for a miracle... But it’s somehow a relief that we now know and don’t have to wait for further tests and uncertainty.
