Brief Summary:
Preterm labor is a leading cause of perinatal morbidity and mortality. Several investigators have reported that ultrasound evaluation of the cervix can predict the risk of preterm delivery. Three-dimensional ultrasound may provide additional information about how to best counsel parents about the chances of premature birth. This technology has the capability for accurate volume measurements of irregular structures that is superior to conventional ultrasound. Therefore, it is possible that three-dimensional ultrasound methods may better characterize cervical changes and the risk for preterm delivery.
Our protocol will attempt to identify prognostic indicators of adverse pregnancy outcome by three-dimensional ultrasound. A maximum of 680 pregnant women with the diagnosis of preterm labor will be prospectively studied to characterize cervical morphology and volume as predictors of preterm delivery risk. These results will be correlated with placental pathology and pregnancy outcome. We will also compare the performance of conventional two-dimensional endovaginal ultrasound with three-dimensional ultrasound findings. This information is expected to improve our understanding about the nature and timing of cervical volume changes in relation to pregnancy outcome.

Our protocol will attempt to identify prognostic indicators of adverse pregnancy outcome by three-dimensional ultrasound. A maximum of 680 pregnant women with the diagnosis of preterm labor will be prospectively studied to characterize cervical morphology and volume as predictors of preterm delivery risk. These results will be correlated with maternal and fetal biological markers, placental pathology and pregnancy outcome. We will also compare the performance of conventional two-dimensional endovaginal ultrasound with three-dimensional ultrasound findings. This information is expected to improve our understanding about the nature and timing of cervical volume changes in relation to pregnancy outcome.
