Screening cervical length in pregnant women with a history of preterm birth

Transvaginal Ultrasound Cervical Length Screening in Singleton Pregnancy With Prior Spontaneous Preterm Birth

Not applicable Interventional Federico II University · NCT02923973

This study tests if measuring cervical length with an ultrasound can help pregnant women who have had a preterm birth before to better understand their risk of having another preterm birth.

What this trial studies

This study evaluates the effectiveness of transvaginal ultrasound cervical length screening in singleton pregnancies of women who have previously experienced spontaneous preterm birth. The aim is to determine if this screening can help predict the risk of preterm birth and guide preventive interventions. The study will involve women aged 18-50 with a history of spontaneous preterm delivery, assessing the cervical length to identify those at higher risk. The findings could lead to improved management strategies for preventing preterm births.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18-50 with singleton pregnancies who have a history of spontaneous preterm birth.

Not a fit: Patients with multiple gestations, ruptured membranes, or fetal abnormalities will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of preterm births and improve outcomes for mothers and infants.

How similar studies have performed: While there is evidence supporting the use of cervical length screening in predicting preterm birth, this specific approach has not been extensively tested in prior studies.
