Abstract

TRAP sequence-is a rare, serious malformation with reported incidence 0.3 in 10.000 pregnancies. The prognoses is lethal for the recipient, whereas perinatal mortality and malformation risks are up to 50 % and 10% in pumping twin. We present three cases of TRAP sequence diagnosed and followed at our institution from August to October 2011. Outcome of TRAP sequence depends on the time of diagnoses, treatment modality and timely delivery.
