Rapid development of hydrops fetalis in the donor twin following death of the recipient twin in twin-twin transfusion syndrome.

| Abstract |
Intrauterine death of one fetus in monochorionic twinning is associated with high rates of perinatal morbidity and mortality in the surviving fetus. Subsequent development of hydrops fetalis in the donor twin after fetal demise of the recipient twin has been described in only two case reports and pathophysiology remains unclear. We report on a monochorionic-diamniotic twin pregnancy complicated by severe twin-twin transfusion syndrome. Ultrasound examination at 20 weeks of gestation showed discrepant twins with oligohydramnios in the smaller twins' sac and polyhydramnios in that of the larger twin. Repeated amniocenteses permitted prolongation of the pregnancy. However, the recipient twin developed deteriorating hydrops fetalis and died at 28 weeks of gestation. After this event, subsequent development of hydrops fetalis in the surviving donor twin could be observed, as well as an increase of amniotic fluid. An elective cesarean section was performed at 29 weeks of gestation. Initial hypoxemia could be effectively treated by high frequency oscillatory ventilation, surfactant therapy and inotropic support. The infant was discharged in good condition at the age of 2 months. Although rare, antenatal demise of the recipient twin in a monochorionic pregnancy can be associated with the subsequent development of hydrops fetalis in the surviving donor twin. We speculate that this phenomenon is due to ischemia-reperfusion injury of the previously poorly perfused twin.
