We then had a more detailed ultrasound done in which all sorts of measurements were taken to look for Down Syndrome markers. I got to watch this entire ultrasound with a separate monitor, so it was really fun and interesting to see his anatomy in so much more detail. We tried to video this second ultrasound, but they wouldn't let us for legal reasons (they don't keep video records themselves, so they don't want us to have them either :-P ) Besides moving around a LOT, everything looked normal except his kidneys were slightly enlarged.
The doctor then came in and explained that the larger kidneys (the cut-off for 21.0 weeks is 4mm and Lloyd's were at 4.1mm), were a soft marker for Down Syndrome. Because of this, they bumped our risk for Down Syndrome from 1 in 98 to 1 in 49. However, she also explained that the enlarged kidneys are seen in normal babies and that generally it clears itself up during the pregnancy and if not, the baby has a tendency for urinary tract infections once born. Apparently this trait is also usually seen in boys probably due to the way that their urinary system is built. She then asked if we wanted to have an Amniocentesis to analyze his genes and see if he did in fact have Down Syndrome. And that was pretty much all the information we got. These weren't exactly the results we expected.
We had to decide that day if we wanted the Amnio. We could come back and do the test, but we needed to do it within the next few days because of the timing of Amnio test results. However, after we were done with the doctor and started talking (in the hall by the way), we had a ton of questions, the answers to which would influence our comfort level with the idea of the Amnio. The risk of miscarriage due to the Amnio procedure were 1 in 1000, so definitely something to be concerned about. We also had a lot of questions about soft markers and their prevalence in children with Down Syndrome (do kids that end up having Downs show more than one? are there certain ones that are more commonly seen? is their a separate risk factor for each marker?).
With the information Brad was able to get online through his Mom while we were in the hall, we decided we didn't want to do the test. We then went home and did some additional online research, including searching through peer-reviewed journals. Basically our decision not to proceed with the Amnio, came down to the fact that what was triggering the 'soft marker ruling' was just 0.1 mm. We also discovered that besides soft markers, there are also medium markers and strong markers. We felt that if there had been several soft markers, a single soft marker that had a stronger tendency to be associated with a Downs case, or we had medium or strong markers, then we might think about the Amnio. We also felt pretty confident that since our one soft marker is also seen in normal kids and that it has a prevalence in boys, that it wasn't something we were going to worry about as being overly 'abnormal'. Finally, given the mood of the office (not directive and very protective), we felt that our risk results were being increased more for legal reasons that for actual cause (God forbid they tell someone not to worry and they end up having a child with Down Syndrome).
We feel really good about our decision. This is not something that we are stressed about or are going to worry about for the rest of the pregnancy. Our guts tell us he is just fine. We will, however, likely have a follow up ultrasound in about two months to check on his kidneys, but other than that, it is back to business as usual for us.
And like the previous Wednesday's ultrasound (when we saw The Raconteurs later that night), we saw Sigur Ros later Wednesday night (wonderful show btw!!!). Lloyd seemed to take after his parents and was a big fan of those gents from Iceland and rewarded both of us by letting us feel his first kicks. I've been feeling him moving around a lot more consistently lately, mostly after I eat a meal, but this was the first time Brad's felt him and I've felt him from the outside. He was also funny last night when I went to bed. I noticed that not only was he all the way at the bottom of my stomach (so it looked almost flat above my belly button, but he was all on the right side! I was like - what are you doing, silly!?! And pretty soon, he evened himself out, but for a little while my stomach looked seriously messed up!
Finally, we got the video of our 20 week ultrasound compressed so that you can see it here. It's about 6 minutes long and you can hear the technician (mostly explaining what you are seeing) and Brad and me (being amazed). I think these are so much fun to watch!
Hope you all have a wonderful weekend this coming weekend and talk to you soon!
