Cervical length screening for prevention of preterm birth in singleton pregnancy with threatened preterm labor: systematic review and meta‐analysis of randomized controlled trials using individual patient‐level data

Abstract

Objective Cervical length screening by transvaginal sonography (TVS) has been shown to be a good predictive test for spontaneous preterm birth (PTB) in symptomatic singleton pregnancy with threatened preterm labor (PTL). The aim of this review and meta-analysis RR, 0.64 (95% CI,; three trials; 287 participants) and a later gestational age at delivery (MD, 0.64 (95% CI, MD, 4.48 (95% CI,

Electrohysterography in the diagnosis of preterm birth: a review

“…A short cervix is significantly associated with an earlier gestational age at delivery and with recurrent preterm birth (Romero et al, 2012). In symptomatic singleton gestations with threatened preterm labor, there is a significant association between knowledge of transvaginal CL and lower incidence of PTB and later gestational age at delivery (Berghella et al, 2017). A sonographic short cervix detected in the second trimester was the best predictor of spontaneous PTB in that study (Berghella et al, 2017).…”

Elastography and Metalloproteinases in Patients at High Risk of Preterm Labor

“…The obtained results lead to the conclusion that the CL expressed in millimeters is inversely proportional to the risk of preterm labor. This is confirmed by the Berghella study, according to which screening the length of the cervix with transvaginal ultrasound is a good prognostic test for the prediction of spontaneous preterm labor in single pregnancies with symptoms of preterm labor [29]. It has been shown that in patients at risk of preterm labor, for whom the cervical length measurement is known, the incidence of spontaneous preterm labor is lower, and the gestational age at delivery is higher.…”
