Perinatal characteristics and outcomes of pregnancies complicated by twin–twin transfusion syndrome

Abstract

Twin-twin transfusion syndrome is a heterogeneous disorder in its clinical manifestations and progress. There remain significant perinatal mortality and morbidity in pregnancies complicated by twin-twin transfusion syndrome, principally related to the high preterm birth rate that typifies this disorder. The severity of disease as assessed by stage and the gestation at delivery are the principal factors in determining perinatal outcome in this condition.
