Serial versus once-only cervical length screening in twin pregnancies

Listen to this summary

The authors aimed to determine the effectiveness of serial versus once-only transvaginal ultrasound cervical length screening in predicting preterm birth in twin pregnancies. Their findings indicated that serial screening significantly increased the incidence of identifying short cervical lengths and improved sensitivity for predicting preterm birth compared to once-only screening. Consequently, the study suggests that serial cervical length assessments should be recommended for better outcomes in twin pregnancies.
