More Ups & Downs

Last Thursday (4/20/23) we went to KU Med for a routine ultrasound. We had been going to KU and a specialist in Overland Park, but KU recommended we do everything in-house there for now. Luckily we only live 10 minutes away, so it is an easy trip. This ultrasound was a bit concerning. The good news is that there was no sign of TTTS and most everything looked OK. The somewhat concerning news was that there was an elevated MCA PSV on Twin B of 1.6 MoM (multiples of the median). Twin A was 1.2 MoM, which is within the normal range.

Twin Anemia Polycythemia Sequence (TAPS) occurs spontaneously in less than 5% of Mo Di twins. Stage one of TAPS is when one twin is anemic with a MCA PSV > 1.5 MoM and the other is polycythemic with a MCA < 1.0 MoM. Although the did not meet this criteria, since B was outside the normal range--being greater than 1.5 MoM--they wanted us to come back on Monday to do another test and make sure that these values had not gotten worse. We therefore had to hold our breath once again.

Luckily, when we went in for the ultrasound and doppler test this past Monday (4/24/23), things had gotten better. Twin A was still 1.2 MoM, which was good, while Twin B had regulated and was down from 1.6 MoM to 1.4, placing her in the normal range. This was a relief, but something that could change week-to-week and will need to continue to be monitored along with everything else. For that reason, we will have ultrasounds every Monday from here on out until the end of the pregnancy. This is week 17 and we have already had six ultrasounds. We therefore will likely have 14-19 more for a total of 20-25 ultrasounds during this process. I think most "normal" pregnancies only have a couple. 

I will plan on updating this blog weekly with the latest results, and photos from the ultrasounds when possible. Below is an image of the ultrasound from last Thursday (we did not get copies of the most recent ultrasound images from this past Monday).
