abstract: Recent advances regarding twin pregnancies have focused on several problems, including the detection and definition of risk in relation to chorionicity, the management of a pregnancy with a single anomalous fetus, the prediction of prognosis and the management of twin-twin transfusion syndrome, and the detection of preterm labor. These questions will be considered in this review.
