Twin-to-Twin Transfusion Syndrome (TTTS)

 

• abnormal blood vessels in the shared placenta cause umbilical cord fusion
• Depending on the number, type and direction of the connecting vessels, blood can be transfused disproportionately from one twin (the donor) to the other twin (the recipient).
• affects identical twin pregnancies
• The common placenta may be shared unequally by the twins
• one twin may have a share too small to provide the necessary nutrients to grow normally or even survive.

Treatment and management:

• surgical interventiaon
