[Empirical report on acute twin-twin transfusion syndrome with single intrauterine death].

We report on a case of acute twin-twin transfusion syndrome in a twin pregnancy in the 26 th under primarily unclear conditions. On admission to the hospital, one fetus was not showing signs of life anymore, while the Doppler indices and CTG of the living fetus showed signs of acute distress. On the scan both fetuses showed adequate and symmetric growth as well as symmetric and normal amniotic fluid amounts, indicating a lack of typical signs for chronic twin-twin transfusion syndrome. The emergency cesarean section performed under the assumption of acute twin-twin transfusion syndrome, which unfortunately could not save the second twin, confirmed our suspected diagnosis.
