The aim of this article is to review current information regarding the management of twin gestations and discuss optimal pregnancy length and considerations regarding route of delivery. Limited data are available on the timing and mode of delivery for twins. ⋯ Cesarean is recommended in twin gestations with monoamnionicity, noncephalic presenting fetus, and those at high risk for combined vaginal-abdominal delivery. The optimal management of twin deliveries is controversial, with timing and mode of delivery dependent on multiple factors, including chorionicity, amnionicity, provider experience, and fetal presentation.

As the incidence of twin gestation increases, it is important to consider the maternal risks associated with carrying multiples. Compared with singleton gestation, there are increased risks to the mother during the antepartum, intrapartum, and postpartum periods. Certain pregnancy complications are more likely to occur during a twin gestation, including preeclampsia and other hypertensive disorders, antepartum hospitalization for preterm labor or abnormal bleeding, nutritional deficiencies, cesarean delivery, and postpartum hemorrhage. Women carrying twins may benefit from early education regarding these issues, close maternal monitoring as well as physical therapy sessions, and nutrition counseling during their pregnancies.
