Significance of ultrasound vaginal cervicometry in predicting preterm delivery (original) (raw)
Acta obstetricia et gynecologica Scandinavica, 2016
The aim of this study is to evaluate the utility of digital examination in addition to ultrasonic measurement of cervical length for predicting spontaneous preterm delivery in women with threatened preterm labor. This was a prospective cohort study in Strasbourg University Hospital, France, between January 2013 and January 2015 All the women with a singleton pregnancy hospitalized with threatened preterm labor between 23 to 34 weeks of gestation were included. Cases of iatrogenic preterm delivery were excluded. A multivariable logistic regression model to estimate the significant predictive parameters of spontaneous preterm delivery was performed. The primary endpoint of our study was a preterm birth before 34 weeks of gestation. A total of 395 women were included in our study. The rate of preterm delivery before 34 weeks was 13%. In univariate analysis every single cervical parameter assessed by the digital examination and all the ultrasound parameters were significantly associated...

Preterm birth is a major cause of death and a significant cause of long-term loss of human potential amongst survivors all around the world. Complications of preterm birth are the single largest direct cause of neonatal deaths, responsible for 35% of the world’s 3.1 million deaths a year, and the second most common cause of under-5 deaths after pneumonia. In this study, an attempt has been made to evaluate the usefulness of cervical assessment by TVS in prediction of risk of preterm delivery in low risk pregnant women, thereby earlier management option can be planned and patients specific treatment can be given at the earliest. The present study was carried out in tertiary care teaching hospital for 1 year from 1 Jan 2019 to 31 Dec 2019. Total of 100 study participants who underwent TVS assessments of cervix regularly followed up who underwent TVS assessment of cervix and were regularly follow up and delivered. The mean cervical length in all these women was 30±6.68 mm. It was obser...
Uterocervical angle: a novel ultrasound screening tool to predict spontaneous preterm birth
American journal of obstetrics and gynecology, 2016
Mechanical alteration of the cervical angle has been proposed to reduce spontaneous preterm birth. Performance of the uterocervical angle as measured by ultrasound for predicting spontaneous preterm birth is poorly understood. We sought to determine whether a novel ultrasonographic marker, uterocervical angle, correlates with risk of spontaneous preterm birth in a general population. We conducted a retrospective cohort study from May 2014 through May 2015 of singleton gestations between 16 0/7-23 6/7 weeks undergoing transvaginal ultrasound for cervical length screening. Images were remeasured for uterocervical angle between the lower uterine segment and the cervical canal. Primary outcome was prediction of spontaneous preterm birth <34 weeks and <37 weeks by uterocervical angle and secondary outcome evaluated cervical length and spontaneous preterm birth. A total of 972 women were studied. The rate of spontaneous preterm birth in this cohort was 9.6% for delivery <37 weeks...

Preterm birth (PTB) is a major obstetric problem associated with high rates of neonatal morbidity and mortality. The prevalence of PTB has not changed in the last decade; thus, the establishment of a screening test and effective treatment are warranted. Transvaginal ultrasound measurement of the cervical length (TUCL) has been proposed as an effective method to screen pregnant women at a higher risk of experiencing PTB. Objective To evaluate the applicability and usefulness of second-trimester TUCL to predict PTB in a cohort of Portuguese pregnant women. Methods Retrospective cross-sectional cohort study including all singleton pregnant women who performed their second-trimester ultrasound (between weeks 18 and 22 + 6 days) from January 2013 to October 2017 at Centro Hospitalar Universitário São João. Results Our cohort included 4,481 women. The prevalence of spontaneous PTB was of 4.0%, with 0.7% occurring before the 34th week of gestation. The mean TUCL was of 33.8 mm, and percent...
Transvaginal Ultrasound as an Indicator of Preterm Birth
Medicinus
Preterm Birth is delivery that occurs when the mother's gestational age is 20-36 weeks starting from the first day of the last menstrual period with a fetal weight still below 2500 grams. In preterm birth there are regular uterine contractions that cause thinning or dilation of the cervix before 36 weeks of gestation is complete. Approximately 50% of sequelae that occur in children are due to preterm birth. It is known that cervical dilatation in pregnant women is associated with preterm birth, so there are several screening methods that are used to predict preterm birth, including cervical length examination. Transvaginal ultrasound examination is a safe method of examination to measure cervical length objectively. Cervical length less than or equal to 25 mm or cervical dilatation 70% to 100% are expected to have preterm birth.
Cervical Assessment by Ultrasound for Preventing Preterm Delivery
Obstetrics & Gynecology, 2009
Background-Measurement of cervical length (CL) by transvaginal ultrasound (TVU) is predictive of preterm birth (PTB). It is unclear if this screening test is effective for prevention of PTB. Objectives-To assess the effectiveness of antenatal management based on TVU CL screening for preventing PTB. Search methods-We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (September 2008), MEDLINE (1966 to September 2008), and reviewed the reference list of all articles. We updated the search of the Cochrane Pregnancy and Childbirth Group's Trials Register on 27 January 2012 and added the results to the awaiting classification section. Selection criteria-Published and unpublished randomized controlled trials including pregnant women between the gestational ages of 14 to 32 weeks screened with TVU CL for risk of PTB. This review focuses exclusively on studies based on knowledge versus no knowledge of TVU CL results.
Accuracy of cervical transvaginal ultrasonography in predicting preterm birth: a systematic review
Journal of Obstetrics and Gynaecology, 2003
This review assessed the diagnostic accuracy of transvaginal cervical sonography in predicting spontaneous pre-term birth. The authors concluded that cervical length and/or funneling can help predict spontaneous pre-term birth in asymptomatic women. Although there were differences among the studies and the diagnostic accuracy depended upon definitions of abnormality, the authors' general conclusions are likely to be reliable.

Background: Preterm birth possess a major health burden to the society due to its long - term morbidity, perinatal mortality and high financial expenditures associated with it. Transvaginal ultrasonographic measurement is an effective and objective way of measuring the cervical length. Cervical length <25 mm is considered as the best cervical parameter with a good predictive accuracy for preterm birth. This study was taken up to study the role of cervical length measurement in predicting preterm labor by Trans vaginal sonography (TVS) and to measure cervical length and follow up cases to study the fetal outcome.Methods: Sagital long-axis view of endocervical canal along the entire length was obtained with high frequency endovaginal probe and the length of cervix from external to the internal os was measured. Atleast three measurements were obtained and the best shortest measurement in millimeters was recorded. Transfundal pressure was applied for 15 seconds and cervical length wa...
