The following clinical features raise suspicion for twin-twin transfusion syndrome (TTTS):

  • Known monochorionic-diamniotic gestation
  • Known or suspected difference in fetal weights
  • Known or suspected difference in the amount of amniotic fluid in each amniotic sac
  • Rapidly expanding abdomen as fluid accumulates in the sac of the recipient twin

Fundal height larger than dates is a common finding because of the production of excess amniotic fluid by the recipient twin.
