SMFM Special Statement: Updated checklists for management of monochorionic twin pregnancy

Approximately 20% of twin pregnancies are monochorionic. The management of monochorionic twin
pregnancy involves several additional interventions beyond the routine management of singletons or
dichorionic twins. In 2015, the Society for MaternaleFetal Medicine posted checklists for monochorionic/
diamniotic twins and monochorionic/monoamniotic twins. The Society presents updated
versions of these 2 checklists reflecting recent changes in practice recommendations. Suggestions for
implementing the use of the checklists into antenatal care practices are also included.
