Abstract

Twin reversed arterial perfusion (TRAP) sequence is a rare and severe complication specific to monochorionic twin pregnancies, involving the presence of an acardiac twin and a structurally normal co-twin (pump twin). We report on the case of a33-year-old female with a biamniotic monochorionic twin pregnancy complicated with TRAP sequence and polyhydramnios. The patient underwent fetoscopic termination of the acardiac twin and at 34 gestational weeks (GW) was readmitted with aretroplacental hematoma. The patient gave birth through caesarean section to a living female fetus, weighing 1480 g. To the best of our knowledge, this is the first case reporting a twin pregnancy with TRAP sequence complicated with retroplacental hematoma.
