To amnio or not to amnio?

Hi ladies.... At my 12 week ultrasound they did the MY scan. BY measured 2.9mm, so just below abnormal which is 3. They then told us it looks like a cystic hygroma may be forming but they couldn't say for sure. We opted for NIPT which came back with no high risks for anything or scans for (and it looks like we are having a boy!) I scheduled a follow up ultrasound for 16 weeks. I know the only way to know is an amnio but am scared I risking a perfectly healthy baby when there appears to be little chance of him being at risk... thoughts? Anyone had an amnio before?

  • NT not MY or BY sorry!

  • I recently was put in a position where I had to make a decision to get an amnio or not.  My baby was diagnosed with CDH, which sometimes comes along with other genetic issues.  Ultimately, I opted not to do it because I just couldn't justify the risk.  I did the bloodwork instead and am waiting on that to come back.  The amnio is more complete and can diagnose a wider variety of things, but we had no soft markers for anything, so we opted to not do it.
  • I’d probably consult with my doctor and try to understand their recommendation. Seems like this can be nothing as long as it goes away by 20wks. If you do go for an amino, find out how many your hospital does. The more they do, the much lower the risk for any complications. And aminos have a very low risk to begin with. 
  • I am facing the exact same choice! Our NT measured at 3.5mm, which is into the abnormal range (although still kind of borderline). We also opted to do the NIPT first and it came back clear. We've decided to wait and see what the ultrasounds tell us, and unless there is some sort of a red flag we probably won't do it. I'm not so worried about the risks of the amnio, because I think they are quite safe now, although of course nothing is guaranteed. But my thought is there is such a thing as too much information. The genetic counselor said that it is pretty common for a microarray to come back showing a "variance of unknown significance" - meaning there is something missing or duplicated in the chromosomes, but it's not associated with a known syndrome etc. While sometimes these could mean a very rare serious issue, often they are just random coding errors that people live with and cause no real issues. The uncertainty of that would drive me bonkers and it doesn't help because it's not like you can prepare before the birth. I feel like I'd just be scared for no purpose!

  • If your blood work came back normal I wouldn’t worry, personally... ultrasounds have a margin of error. Our midwive didn’t even have us do one bc “everything we needed to know” would be provided via blood work. I’d just wait until your next one and if there is concern, go from there. 
  • Thank you all. We have a follow up at 16 weeks and I am praying everything looks good then!
