Management of monochorionic monoamniotic twins: case reports and a review of literatures

Abstract

Monochorionic monoamniotic (MCMA) twins are rare but are associated with higher morbidity and mortality rates than monochorionic diamniotic (MCDA) twins. Although the prenatal prognosis of MCMA pregnancy has improved with advanced prenatal care, no consensus has been reached for the management for MCMA twins. Here, the authors report two cases of MCMA twin pregnancies diagnosed at 30 weeks of gestation and complicated with congenital heart disease, respectively, with a review of literature on MCMA twin pregnancies.
