Hi everyone! I'm 18 weeks along with identical mo/di twin boys.
I went for my anatomy scan earlier this week and one of the boys (baby A) has a 2 vessel umbilical cord. Does anyone have any experience with this? The doctor made sure I left feeling ok about the situation but of course, like an idiot, I started googling things and now I'm worried.
1. It can be a soft marker for trisomy 18. The tech nor doctor could see baby A's face because baby B's head was blocking it. So they will look in two weeks. But baby A's hands and head looked fine which could show other soft markers. Plus Baby B looked ok and I think they would both have trisomy 18 if one did, because they are identical, right?
2. The umbilical cord develops at the same time as the heart and kidneys. So this could mean there are problems with those organs (I actually read that on a bump article I found).
3. I'm sure there is more to be concerned about but I had to stop reading.
4. My doctor said it could cause growth problems because the baby isn't able to get enough nutrients. He said if I weren't already having twins and being monitored for growth they would start monitoring me closely because of this.
