We compared the CL measurement at 30\u201332 weeks based on mode of delivery. We then analyzed our data across four subgroups, based on the CL measurement quartiles at 30\u201332 weeks. We performed this analysis in all patients, and also performed a planned subgroup analysis of 130 patients who attempted a vaginal delivery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In all patients, including those who attempted a vaginal delivery, the mean CL at 30\u201332 weeks was significantly shorter in women who delivered vaginally compared with women who had a Cesarean section. The likelihood of Cesarean delivery increased significantly with increasing CL measurement across the groups defined by measurement quartiles. On adjusted analysis controlling for maternal age, race, <jats:italic>in\u2010vitro<\/jats:italic> fertilization, chorionicity, induction of labor and prior vaginal delivery, the CL measurement at 30\u201332 weeks was independently associated with mode of delivery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In twin pregnancies, the CL at 30\u201332 weeks is significantly associated with the likelihood of Cesarean delivery. A longer CL may represent underdevelopment of the uterus, leading to a higher risk of Cesarean delivery in labor at term. Copyright \u00a9 2012 ISUOG.
