The OB discovered at our 20 week appointment that the boys have
twin-to-twin transfusion syndrome.
Here's a shortened explanation from the
Texas Fetal Center:
In TTTS, the smaller twin (often called the donor twin) does not get enough blood while the larger twin (often called the recipient twin) becomes overloaded with too much blood.
In an attempt to reduce its blood volume, the recipient twin will increase the urine it makes. This will eventually result in the twin having a very large bladder on ultrasound, as well as too much amniotic fluid around this twin. This is known as polyhydramnios. At the same time, the donor twin will produce less than the usual amount of urine. The amniotic fluid around the donor twin will become very low or absent. This is known as oligohydramnios.
As the disease progresses, the donor will produce so little urine that its bladder may not be seen on ultrasound. The twin will become wrapped by its amniotic membrane (known as a “stuck” twin). Often the polyhydramnios of the recipient twin is the first thing noticed by the patient due a sudden increase in the size of the uterus. Clothes may become tight fitting over a short period of time. At other times the differences in the amniotic fluid volumes between the twins is only noted at the time of a routine ultrasound.
Our OB immediately made us an appointment with a maternal fetal medicine specialist, who we saw today. The babies have about 30% difference in weight and the donor baby - the one who is smaller - has almost no amniotic fluid.
We'll be meeting with a super specialist who can do a laser surgery that can potentially correct the problem on Thursday morning in Houston. If he says I am a candidate for the laser surgery (I think the criteria has something to do with the amount of fluid in each baby's sac), I will have surgery that day and be in the hospital probably until Saturday.
We'll keep updating the blog as we find out more info. Tomorrow I will try to post some of the pictures from today's specialist visit - the babies look like Skeletor in some of the pictures!
