Prognosis for twin-to-twin transfusion syndrome

Reading time: 1 min

If the disease goes untreated, then the prognosis is extremely poor for both foetuses. Mortality ranges from 80% to 100%, while 40% of survivors present severe postpartum complications and long-term damage.

The prognosis improves dramatically for twins treated surgically, with at least one foetus surviving in 85–90% of cases, both foetuses in approximately 65% of cases and nowadays only 5% of survivors present neurological complications.
