Objectives: This study measured cervical length (CL) of asymptomatic women with twin pregnancies at 14-16 and 21-24 weeks of gestation and assessed whether the difference between measurements is predictive of preterm delivery (PTD). Methods: This retrospective, cohort study included patients with two consecutive CL, measured with transvaginal sonography at 14-16 weeks of gestation (CL1) and 21-24 weeks of gestation (CL2). Electronic medical records were reviewed for demographic, medical and delivery data. PTD was defined as delivery prior to 37+0 weeks of gestation. CL1, CL2 and the change between scans were evaluated and correlated with PTD. Results: Among 103 twin gestations, 76 (73.7%) women delivered at term and 27 (26.3.) had PTD. CL1 was not a good predictor of PTD (4.2 ± 0.57 cm in PTD group vs 4.1 ± 0.67 cm in term group P = 0.32). The correlation between CL change and PTD was not significant (0.47 ± 0.09 cm in PTD group VS 0.28 ± 0.08 in TERM groupP = 0.2). The correlation between CL change and delivery after 38 weeks was not significant (0.13 ± 0.07 in 38+ group vs 0.34 ± 0.04 in 37-38 weeks group P = 0.3). Baseline characteristics and perinatal outcomes between term and preterm deliveries were similar. Conclusions: Sonographic measurement of CL at 14-16 weeks gestation and the difference between CL in the first and second scans were not reliable predictors of PTD in asymptomatic women with twin pregnancies and in addition cannot be used to predict delivery after 38 weeks.
