Treatment of Twin-to-Twin Transfusion Syndrome (TTTS)

Amnioreduction

Amnioreduction is the removal, through a fine needle, of the excess amniotic fluid from around the recipient twin. This procedure may help decrease the risk of rupture of the membranes and premature labor. It may also temporarily relieve pressure on the umbilical cord.

Amnioreduction does not treat the cause of twin-to-twin transfusion syndrome, only one of its effects. The fluid is likely to accumulate again and the procedure may have to be repeated. With each amnioreduction, the risk of bleeding or infection increases, as does the risk of injury to the membranes.
