Baby's nasal bone appears small...

I am really trying hard not to worry myself over this, but I can't help it.  I just wanted to tell my story in hopes that there may be others with similar experiences.

At 15 weeks I had the Quad Screen done.  The results came back great, our odds for Down's was 1 in 10,000 and the other two results were good as well but I don't know the exact numbers.

We had our anatomy scan at 18 weeks and the tech was having trouble getting a good profile view of our little guy.  Tuesday, a nurse called and said that his nasal bone appeared to be small.  They are sending us to a special u/s place to have another scan done.  I know that this office also does genetic counseling, so it is worrying me that my doctor sent me there.  I know a small or non existent nasal bone is a very strong sign of Down's.  The only thing I'm hanging on to is that our Quad Screen results showed very low chances.  I'm hoping that they just didn't get a very good view of his profile because I know the tech had trouble getting him in a position to get good pictures.

Thoughts and prayers are appreciated.  And any words of advice or other experiences are welcomed as well :)  TIA

    I won't tell you not to worry because I'm sure you will anyways.  Sending you lots of thoughts and prayers.  All I can say is that the view on an ultrasound is not perfect and just because he has a small nasal bone doesn't mean he automatically has DS.  What I did find out was that unfortunately the first tri screen is only 80% accurate (meaning 20% of cases are not caught in the screening).  I really don't want to make you more nervous.  On my daughter's ultrasounds, what the doctors saw convinced them that she had Trisomy 13 and I had an amnio at 30 weeks to check (she didn't - thank goodness!).  They thought they saw rocker-bottom feet, sloped forehead and hand positions that were indicators.  Even after she was born, based on her features, the geneticist thought for sure she had an abnormality and they have not been able to find anything after doing a full genetic array.  So definitely try to keep positive.  The doctors are doing their job by looking into this but it doesn't mean that there is something wrong!

    are you by any chance overweight or carry alot of belly fat? I ask b/c my friend was sent for a better U/S (level II maybe) b/c they could not find the spine. The baby ended up being prefectly fine, she was overweight and had a lil too much fluid wh/ made using a regular u/s not a good option for her.

    I am wishing you the best of luck

    I have a small amount of belly fat but I'm 5'5" and pre-pregnancy weighed around 130.  During the regular u/s he was in a position that wouldn't allow the tech to get a good profile shot of him.  We even went to the dr. appointment and then back to the u/s place to try again.  She got a few shots, but I'm hoping that she just didn't get one good enough to see the nose bone very well.

    Thanks to both of you ladies for your responses.

    The measurements from one shot are not always accurate, even with a good tech.  I just got back from my 20 week ultrasound, and during it the tech commented how baby had really long femurs.  I responded that I thought that was strange, given that my son has short legs and a long torso (2T pants, but 3T shirts to cover his belly).  She measured again a few times, and it turns out that her first measurement was wrong.

    I wish you the best on your next scan.

    Oh my heart goes out to you!  I just did my first tri screening and got "abnormal" results that raised our risk from the average 1 in 800 for Down's to 1 in 175.  I"m beyond terrified and hoping and praying every second of the day that they did something wrong and/or that the baby beats the odds and is just fine.  We are doing an amnio at 16 weeks (in about 10 days) so hopefully they will be able to check the nasal bone during hte ultrasound and tell us SOMETHING at that time...and then we'll have to wait a week or so for the amnio results.  My heart skips a beat everytime I think abotu getting our results back.  Its a less than 1% chance (1 in 175) but still so so scary. My thoughts and prayers are with you!!  I mean it!  Hang in there!
