The Fetal Center is committed to a highly aggressive approach to the overall survival of all twin pregnancies, treating 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.
The below data reflects surgical volume from September 2011 – November 10, 2020. The data represents 530 patients with known outcomes at 30 days post-delivery, specifically highlighting outcomes based on mothers’ cervical length. As noted below, a cervical length of ≥ 1.5 cm was found in 95% of cases at The Fetal Center.
