Therapeutic Reduction Amniocentesis: This is the 'most widely
available therapy' and involves draining the excess amniotic
fluid (polyhydramnios) by inserting a needle into the amniotic
sac of the recipient. It relieves the mother's abdominal discomfort,
and prolongs TTTS pregnancies by reducing the risk of spontaneous
rupture of the membranes or premature labor from the enlarged
uterus. In addition, by reducing the pressure inside the womb,
it has been reported to change the nature of the transfusion
in some TTTS cases. Survival rates with amniocenteses approach
80% in some centers, but health status of surviving infants
are not always reported. Recent reports (see section of Medical
Research and Articles) indicate a 60-75% survival rate with
amniocentesis, but 10-30% of the survivors have had neurological
(brain) abnormalities when ultrasounds were performed in the
nursery. Since the babies remain connected, there is the continuing
transfusion process between the twins (both chronic and acute).
This may explain the higher rate of medical problems in the
surviving babies than methods that disconnect the babies.
Amniotic Septostomy: This is the intentional creation of a
hole in the membrane septum between the babies' bags of water
with a needle during ultrasound scanning. It allows for some
of the excess amniotic fluid in the recipient's bag of water
to enter the sac of the donor who usually has no to very little
amniotic fluid. In one report of 12 TTTS cases, the septostomy
to delivery interval was 8.5 weeks and 83% (20/214) of the
twins survived. The health of the surviving twins was not
given. The babies remain connected with this, and there is
now the additional risks associated with twins who sit in
the same sac (monoamnionic) such as possible umbilical cord
entanglement.
Medication Therapy: Several drugs have been used in TTTS cases
for various purposes. These include:
Digoxin
Therapy for Fetal Heart Failure: Here doctors give this heart
medication as pills to the mother, or inject it directly into
the twin that is showing signs of heart failure. Giving this
medication may help the heart beat stronger when it is overloaded
with blood.
Indomethacin
Therapy to Curtail Amniotic Fluid Production: Here doctors
also give this mediation to the mother hoping to decrease
the urine output in the recipient and lessen the amount of
polyhydramious. Indomethacin is an aspirin-like medication
(non-steroidal anti-inflammatory drug) with numerous side
effects in the baby, one of which is on the kidney where decreased
urine production occurs. It is the most powerful drug for
treating pre-term labor and is used more often for this purpose
in TTTS. When used as a single treatment for TTTS cases, the
results have been disappointing.
Tocolytic
Medications to Stop Premature Labor: In addition to indomethacin,
there are several other drugs that are used in TTTS cases
to stop labor.
Sophie and Sara
I underwent the laser surgery on August 14th, 2002, at only 18 1/2 weeks of pregnancy. In the operating room, Dr. De Lia keeps prayer cards of Saints Gerard and Jude, the patron Saints of pregnancy and hopeless causes. Just before the surgery, we said a prayer together and asked St. Gerard to help our babies stay strong. I drifted off under the anesthesia, knowing that I was in the hands of a faith-filled surgeon who is totally dedicated to saving little twin babies with TTTS. On December 15th, 2002, over eighteen weeks after their in-utero surgery, our beautiful little angels Sophie and Sara were born
