PSA: the REAL risk of amnio miscarriage

As a s/o from the post below. It irks me when the uninformed quote stats on this topic. Clearly if you're quoting a 1/200 miscarriage rate on an amnio you've never met with a peri to discuss it, let alone experienced an amnio yourself.

I met with my Peri at Duke University Hospital 2 weeks ago who informed me that the real/new stats (versus those of 20 years past) are:

1/1600 for amnio

1/1200 for cvs

I realize that these risks are still too high for some, but it's important to know/ disseminate the real data, not just outdated info from the googles. Not trying to flame, just trying to squash the myths since this is an important topic and misinformation is scary.

Re: PSA: the REAL risk of amnio miscarriage

  • I saw your post and noticed you mentioned Duke - so are you in the Raleigh area?  Good luck with everything and thanks for the info.
  • Thank you for this. I hate to see misinformation getting spread around. So many people take what they read on message boards as fact over and above even what they are told by their doctor.

    It depends heavily on who is doing the amnio, but even then you can still get an infection they can trigger labor and loss.  This happened to a friend of mine.  The numbers you quoted sound significantly better than what I have seen on Medline.  Maybe he is referring to Duke's stats, which I imagine are superior given that it is an academic medical center.

    I totally agree with you.

  • Thank you!!

    For the love of it all, in every single response I write to someone asking about thee procedures I mention that the statistics often cited (like by that nurse, remember that one?) are outdated! It's important to ask for the success rate of the procedure in the hands of the person or facility performing it. I should have it as a canned response saved somewhere :)

  • Thanks for the info; unfortunately, many baby books (WTEWYE for one, I think Girlfriend's Guide as well) still quote the 1/200 stats.  So there is widespread misinformation, and not for lack of research. 

     

    You're right; discussing w/ the doctor/specialist and collecting as much information as possible is vital.

     

    Good luck!

    THANK YOU.

    My doc also pointed out that some of the increased risk from CVS is likely due to the fact that it is performed in the first tri, when the risk of m/c in general is still higher - in other words, some of those miscarriages would have happened anyway, regardless of the CVS...

  • Thank you!

    I had to step away from the google when making my decision, and I asked my doctor what his particular rates were and what he thought.

  • I had my amnio yesterday and had this discussion with my peri and she said the same thing you said.  1/200 is and outdated number.  Thank you for bringing this up.

    You're right. I wouldn't personally get an amnio or cvs from a 'regular' OB (that makes them sound so untrained!). But these new stats take into account all miscarriages as a result of all amnios/cvs regardless of the administrator (I asked specifically). I imagine the experienced expert has a lot lower m/c rate. My peri has never 'caused' one personally.

  • For anyone who is interested, here is a link to the abstract of a 2006 article published in Prenatal Diagnosis. 

    http://www.ncbi.nlm.nih.gov/pubmed/16838383?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DiscoveryPanel.Pubmed_Discovery_RA&linkpos=2&log$=relatedarticles&logdbfrom=pubmed

    There are other related articles on the side you can read as well. 
  • Agreed. I read this a year ago - about the stats changing because doctors have become more skilled. The old numbers are still quoted most regularly, unfortunately.
  • Thank you!  I totally agree with you.  I had amnios with each pregnancy after learning my dr.'s complication rate.  Unfortunately many books have the outdated information.

    Love to see folks here from my hometown! Wink  I didn't see OP re: amnio, but I'm very happy to cough up the dough for the quad screen to avoid the amnio.
