This is my 25th week of pregnancy and I have officially been put on bed rest since my 24th week... only I haven't been taking it very seriously. It has been really difficult for me to go from moving around every minute of the day to laying in bed all day. This is crucial for the babies, though, because they have some Twin-to-Twin Transfusion. To help you better understand what it is, I did some research and this is what I found:
As a result of sharing a single placenta, the
blood supplies of
monochorionic twin fetuses can become connected, so that they share blood circulation: although each fetus uses its own portion of the placenta, the connecting blood vessels within the placenta allow blood to pass from one twin to the other. Depending on the number, type and direction of the interconnecting
blood vessels, blood can be transferred disproportionately from one twin (the "donor") to the other (the "recipient"). The transfusion causes the donor twin to have decreased blood volume, retarding the donor's development and growth, and also decreased
urinary output, leading to a lower than normal level of
amniotic fluid. The blood volume of the recipient twin is increased, which can strain the fetus's heart and eventually lead to heart failure, and also higher than normal urinary output, which can lead to excess amniotic fluid.
In early pregnancy (before 26 weeks), TTTS can cause both fetuses to die, or lead to severe
disabilities. If TTTS develops after 26 weeks, the babies can usually be
delivered alive and have a greater chance of survival without disability.
Other than requiring a monochorionic-diamniotic twin (or higher multiple) pregnancy, the causes of TTTS are not known. It is not known to be hereditary or genetic.
Some doctors recommend complete bed-rest for the mother coupled with massive intakes of protein as a therapy to try to counteract the syndrome. Theories for why this would be effective vary, but some doctors claim to have seen it help. There are, however, no formal clinical trials indicating that the
bed rest / high-protein diet is effective.
If the situation persists, there is a chance that I might have to go in to surgery to split the babies' placenta into two placentas using a laser. We are hoping that it won't get that severe. I have been resting a little more these last few days, and it has made some difference, but there is still a great concern, and I have to keep resting. Other than that, there is not much that can be done, and it all rests in the Lord's hands. All we can do now is pray that the babies will grow at the same rate and that the difference in growth will decrease so that it is not a concern anymore.
