SIOUX FALLS, SD -- Statistics from the C.D.C. show that 32.2 out of 1,000 pregnancies involve twins. However, only about 20% of twins are monochorionic (share the same placenta). That means that only 6.44 pregnancies in 1,000 are monochorionic pregnancies. The reason that this is significant is that only monochorionic twins can develop Twin-Twin Transfusion Syndrome.
Dr. DeLia, a fetal surgeon in Chicago, was the doctor who invented the procedure that treats Twin-Twin Transfusion Syndrome – fetoscopic laser photocoagulation. Monochorionic twins can be in one sac or two sacs. For some reason, Twin-Twin Transfusion Syndrome (TTTS) is more common in cases of two sacs. Overall, about 15% of all monochorionic twins have some degree of TTTS. That translates to 0.97 in every 1,000 pregnancies.
There are a number of ways to treat TTTS, any of which may be the correct method depending on ultrasound findings and the gestational age of the pregnancy. The various therapies that are available target either the unequal fluid between the twins’ sacs, or interrupt the blood vessel communications between the twins on the single shared placenta. The available therapies currently used are:
A. Amnioreduction – This is a series of amniocentesis that involves removal of the excess amniotic fluid from the sac of the recipient twin. This restores the balance of the fluid in the two sacs and improves uteroplacental blood flow.
B. Septostomy (microseptostomy) – This procedure creates a hole in the membrane between the two babies’ sacs allowing the excessive fluid from the recipient twins’ sac to flow to the donor twin’s sac, which is low or absent in fluid. This procedure is performed with an amniocentesis needle.
C. Fetoscopic Laser Photocoagulation – The most successful procedure is Fetoscopic Laser Photocoagulation, invented by Dr. DeLia. This is the laser ablation of the communicating vessels on the placenta between the twin fetuses. This procedure can be curative because the babies are no longer sharing blood vessels between them.
About one third of the TTTS babies need to be operated on. That means that an operation is needed in 0.32 pregnancies for every 1,000 pregnancies, or 1 in 3,000. Since there are about 11,000 births in South Dakota, each year, that means that there will be, on average, about 4 times a year where this procedure would be needed.
Depending on where the procedure is performed, between 79% and 85% of time, at least one baby survives. Between 55% to 64% of the time, both babies survive. That means that, on average, about 2 times a year, a baby will die despite the efforts to save the babies. The medical profession does not deliberately kill one of the babies. There is no need to do that. “Selective Termination” or “Selective Reduction” is never needed.
It is a violation of Section 2 of Initiated Measure 11 only if the procedure is intended to kill the child. The procedures I outlined are never intended to kill the child, but are always intended to save the life of the child.
It is absolutely absurd for Planned Parenthood to suggest that this law prohibits these procedures just because there is a risk the children can die. By the way, if the TTTS babies die, it is usually from the underlying condition, not the surgery. The condition kills them because the surgery failed to save them.

This a a factual and well-written brief on the facts of TTTS. The Planned Parenthood [sic] arguments are absurd and deceitful. But, we've come to expect nothing less from those who claim that "choice" trumps life.
