Cerclage After Full Dilatation Caesarean Section
Summary
CRAFT-OBS: Observational Study; To evaluate subsequent pregnancy risk of preterm birth in women with a history of previous caesarean in established labour. This prospective study using clinically acquired cervical length and quantitative fetal fibronectin data will help establish a predictive model of preterm birth <34 weeks and <37 weeks.
CRAFT-RCT: Randomised controlled trial arm; To assess treatment for short cervix in women at high risk of preterm birth following a caesarean section at full dilatation
CRAFT-IMG: Imaging sub-study; To aid understanding of micro and macrostructural features within the cervix which predisposes to preterm birth in women with a previous full dilatation caesarean section. This will use MRI and an advanced transvaginal ultrasound protocol and to assess if structural changes can be visualised in the cervix.

Cerclage for Singletons With Short Cervix Without Prior Preterm Birth
Preterm birth remains the most common cause of perinatal morbidity and mortality. A short cervi- cal length on transvaginal ultrasonography has been shown to be one of the best predictors ...
The aim of this study is to evaluate the efficacy of cervical cerclage in prevention of spontaneous preterm birth in singleton pregnancies with a short transvaginal cervical length (
Spontaneous preterm birth (SPTB) remains the number one cause of perinatal mortality in many countries, including the United States. In singleton gestations a short cervical length (CL) on...
Pessary as Adjunctive Therapy to Cerclage for the Prevention of Preterm Birth
Cervical cerclage was devised in the 1950's for women with prior early preterm births (PTB) who developed a dilated cervix detected by manual exam in the second trimester. In contemporary ...
Spontaneous Preterm Birth Marker Test
The prediction of preterm birth is beneficial because it initiates early treatment to minimize risk. It defines a population at risk to provide particular treatment and may lead us to a be...

To assess the value of transvaginal ultrasound parameters after cerclage placement in estimating the risk of spontaneous preterm birth.
A recent Cochrane review concluded that cervical cerclage reduces preterm birth before 37, 34 and 28 weeks of gestation and also probably reduces the risk of perinatal death. Transabdominal cerclage w...
Primary, secondary, and tertiary preventions of preterm birth with cervical cerclage.
To evaluate the efficacy of cerclage in preventing preterm birth according to indication.
Vaginal cerclage (a suture around the cervix) is commonly placed in women with recurrent pregnancy loss. These women may experience late miscarriage or extreme preterm delivery, despite being managed ...
To report on our center's experience of a novel modified approach for laparoscopic cervical cerclage and to evaluate its safety and efficacy preliminarily.
Medical and Biotech [MESH] Definitions
Cervical Length Measurement
A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.
Tocolytic Agents
Drugs that prevent preterm labor and immature birth by suppressing uterine contractions (TOCOLYSIS). Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists. The use of intravenous alcohol as a tocolytic is now obsolete.
Cerclage, Cervical
The surgical closure of the incompetent cervix uteri with suture material.
Indel Mutation
A mutation named with the blend of insertion and deletion. It refers to a length difference between two ALLELES where it is unknowable if the difference was originally caused by a SEQUENCE INSERTION or by a SEQUENCE DELETION. If the number of nucleotides in the insertion/deletion is not divisible by three, and it occurs in a protein coding region, it is also a FRAMESHIFT MUTATION.
Infant Mortality
Postnatal deaths from BIRTH to 365 days after birth in a given population. Postneonatal mortality represents deaths between 28 days and 365 days after birth (as defined by National Center for Health Statistics). Neonatal mortality represents deaths from birth to 27 days after birth.
