What is a consequence of twin to twin transfusion?
One twin — the donor twin — gives away more blood than it receives in return and runs the risk of malnourishment and organ failure. The recipient twin receives too much blood and is susceptible to overwork of the heart and other cardiac complications.
How fast can twin to twin transfusion happen?
Twin-to-twin transfusion syndrome typically develops between weeks 16 and 26 of a woman’s pregnancy. But an ultrasound as early as 10 to 14 weeks can put doctors on alert that there is a twin gestation, and if they are sharing a placenta. TTTS is diagnosed by measuring levels of amniotic fluid.
How is twin to twin transfusion diagnosed?
A twin to twin transfusion syndrome diagnosis is confirmed by ultrasound. The condition becomes evident when the ultrasound images show that one child has extra amniotic fluid and the other child has significantly decreased amounts. Abnormalities in the blood-flow patterns in the umbilical cord may also be found.
What causes twin to twin transfusion?
The exact cause of TTTS is not fully understood. However, it is known that abnormalities during division of the mother’s egg after it has been fertilized lead to the placental abnormalities that can ultimately result in twin-twin transfusion syndrome.
How common is twin to twin transfer?
Twin to twin transfusion syndrome (TTTS) is a rare complication of pregnancy that develops in 10-15% of twins when the babies share the same placenta (monochorionic). TTTS can occur in any gestation, even triplets or quadruplets, when two or more babies share their placenta.
Can one twin survive TTTS?
Our center was one of the first in the world to perform fetoscopic laser to treat TTTS. Survival rates for at least one twin are greater than 85% and for both twins is approximately 60% at our center.
How do you prevent twin to twin transfusions?
TTTS is caused by abnormal connections between twins that form when the placenta first develops. This is a purely mechanical and random event that can’t be avoided. “The mother can do absolutely nothing to prevent it,” says Dr.
