Outcomes by Cervical Length

In order to give patients the best chance for a positive outcome relevant to the severity of their condition, The Fetal Center is committed to a highly aggressive approach to the overall survival of all twin pregnancies.  We treat some of the rarest and high risk cases, including mothers with a cervical length of less than 1.5 cm, which increases a mother’s risk of spontaneous preterm birth by almost 50 percent, according to the American Journal of Obstetrics and Gynecology.

Note – Those with a cervical length of less than 1.5cm are at increased risk and should be seen by a physician as soon as possible. Please call The Fetal Center at 832.325.7288.
