Multifetal gestations have increased significantly in the past 30 years, mostly due to the increase in fertility treatments. Diagnosis can be made as early as 5 weeks gestation. Determination of both chorionicity and zygosity is most accurate early in pregnancy. Maternal and fetal complications are elevated in multifetal gestations, and such patients should receive specialized prenatal care [1].
