Twin girls born November 7, 2012 are surviving and thriving, despite a dangerous complication that threatened them in the womb. The girls, Kate and Annie Carlson, were monoamniotic-monochorionic twins, encased in a single chorion and sharing a single amniotic sac. This condition, which only impacts monozygotic -- or identical -- twins, creates a dangerous situation in the womb where the babies' umbilical cords can become entangled and compressed, threatening their survival. Fortunately, Kate and Annie were delivered in time. They remain in the hospital due to their premature birth, but are doing fine.
The Carlson twins' situation illustrates the need for careful medical monitoring of multiple pregnancy where complications such as mo-mo twinning, and other risks may be present.
