What is twin-to-twin transfusion syndrome?

Twin-to-twin transfusion syndrome (TTTS) is rare and results from disproportionate blood supply between two (or more) identical fetuses that share a single placenta. One twin, the donor twin gives away more blood than it receives and has a risk of malnourishment and organ failure. The recipient twin receives too much blood and risks overworking the heart and other cardiac complications.

  • Rapid increase in abdominal circumference (waist size)

  • Feel my child is moving less. (Decreased fetal movements)
