Twin to Twin Transfusion Syndrome (TTTS)

Twin to Twin Transfusion Syndrome (TTTS) is a rare but life-threatening condition that affects 10 to 15 percent of identical twins that share a placenta (monochorionic twins). TTTS can also occur in triplet or higher order pregnancies with monochorionic twins.

TTTS  can have serious consequences to the babies so you will need to be monitored very closely by your doctors.

Find more information about TTTS and how we're raising awareness to fight it here.

If you are worried please talk to your midwife and doctors as they are best placed to explain your situation and treatment options for you.

Our Twinline listening service can provide a reassuring listening ear so you are not alone but we do not provide medical advice.

TTTS can be life-threatening If untreated, 90 percent of babies are likely to die. Even with treatment, 50 percent of surviving babies are likely to be disabled or have a long term condition.
