Preterm birth: the value of sonographic measurement of cervical length

BJOG: An International Journal of Obstetrics & Gynaecology, 2006
Transvaginal ultrasound scanning of cervical length at approximately 20 weeks of gestation in women attending for routine antenatal care is useful for predicting the likelihood of spontaneous early preterm birth. The risk of early birth increases exponentially with decreasing cervical length in both singleton and multiple pregnancies.

Consistency in the transabdominal ultrasound measurement of cervical length in mid‐pregnancy

Australasian Journal of Ultrasound in Medicine, 2022
AbstractPurposeThe Western Australian Preterm Birth Prevention Initiative recommends a transabdominal cervical length (TACL) measurement at the mid‐pregnancy ultrasound to screen low‐risk women for preterm birth risk. In view of this recommendation, we assessed the inter‐observer consistency of TACL screening in mid‐pregnancy.MethodsRoutinely collected

Sonographic measurement of cervical length and risk of preterm delivery

Journal of Obstetrics and Gynaecology Research, 2011
AbstractAim:  To study the relationship between cervical lengths measured by ultrasound and risk of preterm delivery.Material & Methods:  We examined 209 women with singleton pregnancies. The inclusion criteria were women who presented with regular and painful contractions (≥2 contractions at intervals of 10 min for at least 1 h). Transvaginal scan

Cervical length in normal pregnancy as measured by transvaginal sonography

International Journal of Gynecology & Obstetrics, 1997
Cervical length may have potential use as a predictor of preterm delivery [1,2] and diagnosis of cervical incompetence. To determine the risk of preterm delivery or outcome of cervical incompetence, a normogram of cervical length for each period of pregnancy is essential.

Observations on the Sonographic Measurement of Cervical Length and the Risk of Premature Birth

Journal of Maternal-Fetal and Neonatal Medicine, 1999
There is increasing evidence that sonographic measurement of cervical length may be a useful predictor of the risk of spontaneous premature birth. The purpose of this study is to determine whether the measurement of cervical length in a high-risk population at 24 weeks gestation, or the relative change over 24-28 weeks gestation, is more accurate in ...

Pitfalls in Ultrasonic Cervical Length Measurement for Predicting Preterm Birth

Obstetrics & Gynecology, 1999
To describe the anatomic and technical difficulties encountered with transvaginal ultrasound imaging of the cervix in a consecutive series of women at risk for preterm delivery.Three groups of women had cervical ultrasound examinations: those with histories of preterm birth, those with incompetent cervices, and those admitted for preterm labor that did

Progressive Cervical Length Changes versus Single Cervical Length Measurement by Transvaginal Ultrasound for Prediction of Preterm Delivery

Gynecologic and Obstetric Investigation, 2007
<i>Background:</i> To evaluate cervical length changes as predictors of preterm delivery. <i>Methods:</i> Two hundred and fifty-seven pregnant women underwent transvaginal ultrasound examination at 16 and 24 weeks of gestation. Cervical length was measured and the difference between the 2 measurements was calculated.

Prominent cervical mucous and its impact on cervical length measurement: Findings of a national survey

Australian and New Zealand Journal of Obstetrics and Gynaecology, 2014
Cervical length measurement by transvaginal scanning (TVS) has been proposed by some as a universal screening test for preterm labour. The presence of prominent cervical mucous may affect assessment of the cervix; however, the exact technique to measure the cervix when there is prominent mucous or funnelling has not been described.

Methods of sonographic cervical length measurement in pregnancy: A review of the literature

The Journal of Maternal-Fetal & Neonatal Medicine, 2006
In this review we give an overview of the methods and pitfalls in cervical length measurements. We compared the different techniques and investigated factors that influence visualization of the cervix. The data in this overview may be used to establish guidelines in clinical practice.

Gestational Age at Cervical Length Measurement and Incidence of Preterm Birth

Obstetrics & Gynecology, 2007
To estimate the risk of spontaneous preterm birth based on transvaginal ultrasound cervical length and gestational age at which cervical length was measured.Women at high risk for spontaneous preterm birth and with transvaginal ultrasound cervical length measurements between weeks 12 and 32 were identified at one institution between July 1995 and June ...
