(Un)Expected News

On Friday Sean and I headed up to Portland for an appointment at OHSU to have a Nuchal Translucency scan (NT Scan). This basically checks for markers that may indicate a problem early in the pregnancy. They use a high resolution ultrasound and take a lot of measurements. It was amazing how much we could see at such an early gestation.
After the scan the perinatologist came in and started another scan. I kinda figured something was wrong at this point because she appeared to be looking for something specific. I was right... she explained that we have a single umbilical artery (SUA), this can be a marker for quite a few other issues. The most serious of these conditions being Trisomy 18, which is not compatible with life. However, babies with Trisomy 18 usually have their hands balled up into fists and the nuchal fold would be enlarged (over 3 mm is considered abnormal). On the second scan we saw baby's hands wide open and waving at us, the nuchal fold was 1.8 mm. These were very good things and they are confident that our baby does not have this condition. We had a blood test and will know more when those come back next week.
A normal umbilical cord has 2 arteries and a vein, ours is missing one of the arteries. They explained that this occurs in about .5-1% of singleton pregnancies, 50% of babies with this condition are born completely healthy, 25% have heart or renal defects and the other 25% have negative outcomes. I truly believe in my heart that we will be in the healthy category, but just to be safe, we will have another high resolution ultrasound in 4 weeks. The doctor said that we will likely have an ultrasound monthly and regular monitoring towards the end of pregnancy to be sure that baby is getting adequate oxygen and nutrients. (Most SUA babies are a little on the small side at birth).
Sean tells me that I need to stay positive about this, and I think I am... I'm not as much a wreck as I thought I'd be. A lot of that has to do with having such good explanation from the doctor at the appointment, and a lot of it has to do with my gut feeling. I mentioned before that I just knew something was wrong... and while I was right, I also know that things will turn out for the best. We are strong enough to take on anything together, and we have the most wonderful families anyone could ask for.
I'll keep you all updated, until then... some pictures! (I think it's about time for some belly pictures, no? I'll do it soon.)


P.S. Doctor said she could see gender, I told her we didn't want to know... now Sean is all agitated that she knows and he doesn't;-)

That prenatal testing is some scary stuff. I've been there, not same story, but similar. Also have a friend whose baby had the same thing as yours, and she is perfectly fine. Glad your gut is helping you stay positive :)

Talk about knowing when to go with your gut feeling. I think it's amazing that not only did you know that you needed to go for extra testing, but that the doctor was willing to do them as well. I'm glad that things are looking good so far!

You've got some strong momma's instinct Lindsey!!
I'm sorry that you've got something to worry about. I also had a friend with the same thing when she was pregnant with her first. She now has 3 healthy boys.

My fingers will be crossed for you.

PS - He/she looks perfect to me.

I know this little baby will be perfect, just like Natalee. I'm confident that OSHU will take good care of you...they have the best doctors and state of the art technology. You'll be in good hands.
