Transvaginal ultrasound for Cervical length

Universal cervical length screening" refers to the practice of routinely measuring the length of a pregnant woman's cervix using transvaginal ultrasound during mid-pregnancy, typically between 18-24 weeks gestation, to identify those at high risk of preterm birth.

Why is it important?

The cervix plays a crucial role in maintaining a healthy pregnancy by keeping the baby safely inside the womb until term. If the cervix shortens or opens too early, it increases the risk of delivering before your due date, which can lead to long-term health challenges for the baby. Universal cervical length screening means that every woman should have the opportunity for this screening technique. TVUS helps identify women at higher risk early, enabling interventions like vaginal progesterone treatment or cerclage to lower this risk.

Studies show that Universal TVUS for cervical length is associated with a ~25% decrease in neonatal death, potentially saving hundreds of newborns. 13 current medical societies, including ISUOG (International Society of Ultrasound in Obstetrics and Gynecology), recommend this screening. The examination is cost-effective and covered by insurance companies.
