title: Fetal intervention for complications of monochorionic twinning.
abstract: All multiple gestation pregnancies have a significantly higher risk of fetal morbidity and mortality than singleton pregnancies. The risks become progressively greater as the number of fetuses increases. Among twin pregnancies, there is a greater danger of an adverse outcome when the twins share a single placenta (monochorionic), than if each has a separate placenta (dichorionic). A still greater danger exists when monochorionic twins also share a single amniotic sac. Fetal surgical interventions now exist to treat many of the complications associated with twin gestation pregnancies.
