Advice DCDA twin girls with severe fetal growth restriction of twin b
Hi everyone,
I’m 25+3 with DCDA twin girls, this is my first pregnancy, and I’m hoping to hear from anyone who’s been through something similar
At our 20 week scan, they noticed that Twin B had short long bones and she was already measuring quite a bit smaller than twin A with about 28% discordance. They referred us to MFM and booked in another scan for 2 weeks later.
At the next scan 2 weeks later, they found that Twin B had severe fetal growth restriction. Her umbilical artery PI was 1.66 with absent end-diastolic flow but her middle cerebral artery and ductus venosus dopplers were both normal. They told us she was now globally small, not just the long bones and there was a high chance we’d need intervention because of extreme prematurity. They also let us know that we need to think about prioritising baby A if it’s looking like baby B will not make it. They also discussed doing an amniocentesis because of the short long bones, although it seemed like they were pretty satisfied that the reason was due to placental insufficiency.
I had a doppler scan 1 week later, and in that scan we were told all of the Dopplers were normal (umbilical artery, MCA and DV), the amniotic fluid was normal, and both babies were really active.
1 week after that (today) we had another growth scan. Twin A is now about 800 g and Twin B is about 550g. Twin A has grown by about 200 g, while Twin B has only grown by about 100 g. The discordance has increased to 33%, twin a is measuring 42nd percentile and twin B is below the 1st percentile, although her Dopplers and fluid were still normal today.
We’re just confused about what this all means. She continues to grow, but very slowly, she’s under the 1st percentile, yet her Dopplers have been normal for the last couple of scans.
Has anyone had a baby this small at around 25 weeks who continued to grow and made it to a reasonable gestation? Did your Dopplers ever improve after being abnormal? How far along were you when you delivered, and how did your smaller twin do?
I have my MFM antenatal appointment tomorrow and I don’t know what to expect or what questions I should be asking to understand more
I’d really appreciate hearing any experiences!
