What is Twin-to-Twin Transfusion Syndrome (TTTS)?

Posted on Posted in Stories

Twin to twin transfusion syndrome (TTTS) occurs only with identical twins or higher order multiples who share a single placenta. It takes place when there is a connection in the two babies’ blood vessels of their shared placenta. One twin, called the “recipient” has greater blood flow and the other, called the “donor” has inadequate blood flow.  Another name for twin-to-twin transfusion syndrome chronic inter-twin transfusion syndrome. In severe cases the fetuses be of significantly different size; the “recipient” twin may have congestive heart failure and polyhydramnios; the “donor” twin may suffer oligohydramnios.

Prenatal treatments and outcomes for TTTS have improved in recent years.
