I have a very elevated risk for DS because both my parents had siblings with Downs. I had my first appt with my doctor today (who has also been my GYN for the past several years) and she knows about my family history and suggested a CVS as an option. I am going to meet with a genetic specialist next week to learn more about it and nail down exactly what the risks are. As I see it, the pro's are that it screens for pretty much all the genetic disorders with very high accuracy (making an NT Scan - which has a a high rate of false positives - obsolete). It is done early (week 11/12) as opposed to an amnio (which is done week 16-20) which seems much better if we did decide to terminate. And a fun bonus: you find out the sex!The con is that is does carry the risk of m/c (about .5% chance) since they do have to take cells directly from the placenta.I have to hear what the genetic specialist says, but right now that chance of m/c scares me but the idea of finding out something is wrong at 20 weeks and THEN having to make a decision to terminate scares me even more.If you decided to do it, how did you come to that decision and are you glad you did it? Not trying to start a debate about terminating if something is wrong.Thanks!

Re: XP: Did you do a CVS?
I just did a paper on this.
My thoughts, would you terminate the pregnancy if something did come back abnormal? There is a chance of m/c and you carry a higher risk of your baby having a clubbed foot. Many times the results are wrong. The test is preformed at a time that is most convienent to terminate, not at the most accurate time. If you do decide to have the CVS, do it later in the pregnancy when it is the most accurate. If you are not up to the challenge of handling a special needs child, you could always put it up for adoption. That's my view on it.
Thanks. I didn't realize that doing it later made it more accurate. What about an amnio vs a CVS (or are they really the same thing and it is just a timing issue)?
To answer your question, depending on what came back we might terminate, yes.
CVS collects a small sample of cells from the placenta. The amnio collects amniotic fluid from the uterus. Same results but the CVS is done earlier than an amnio. CVS is also associated with higher risks of a m/c. The earlier the test is done the higher the chance of m/c. The most accurate time to do it is after you are 20 weeks.
I'm not saying I wouldn't have the test done. You have family history of Down's so I don't blame you one bit. You wouldn't want to terminate a pregnancy when there is nothing wrong with your LO though. Wait until you are a little further along to have the test done. You want the most accurate result. If it comes back abnormal then you can still terminate the pregnancy if that's what y'all choose to do.
