“…Fukami et al reported that the absence of CGA at second trimester ultrasonography appeared to be new and powerful predictor of PTD before 32 weeks gestation [58], similar to that reported by Pires et al [59] (Table 4). Asakura et al reported that short CL (<20 mm) with absent CGA represents an independent predictor for PTD.…”

Preterm delivery (PTD), defined as birth before 37 completed weeks of gestation, is the leading cause of perinatal morbidity and mortality. Evaluation of the cervical morphology and biometry with transvaginal ultrasonography at 16–24 weeks of gestation is a useful tool to predict the risk of preterm birth in low- and high-risk singleton pregnancies. For instance, a sonographic cervical length (CL) > 30 mm and present cervical gland area have a 96-97% negative predictive value for preterm delivery at <37 weeks. Available evidence supports the use of progesterone to women with cervical length ≤25 mm, irrespective of other risk factors. In women with prior spontaneous PTD with asymptomatic cervical shortening (CL ≤ 25 mm), prophylactic cerclage procedure must be performed and weekly to every two weeks follow-up is essential. This article reviews the evidence in support of the clinical introduction of transvaginal sonography for both the prediction and management of spontaneous preterm labour.

For primary prevention, an effective, affordable and safe intervention applied to all mothers without preceding testing is likely to be the most cost-effective approach in asymptomatic women in early pregnancy. For secondary prevention among women at risk of preterm labour in later pregnancy, a management strategy based on the results of testing is likely to be more cost-effective. Implementation of a treat-all strategy with simple interventions, such as fish oils, would be premature for asymptomatic women. Universal provision of high-quality ultrasound machines in labour wards is more strongly indicated for predicting spontaneous preterm birth among symptomatic women than direct management, although staffing issues and the feasibility and acceptability to mothers and health providers of such strategies need to be explored. Further research should include investigations of low-cost and effective tests and treatments to reduce and delay spontaneous preterm birth and reduce the risk of perinatal mortality arising from preterm birth.

“…14 In a study by Pires CR et al in conducted a prospective cohort study of 338 uncomplicated pregnancies was evaluated by trans-vaginal sonography between 21 and 24 weeks of gestation. 5 They concluded that CL less than 2 cm and non-detection of CGA showed a strong association with preterm delivery. The result seems to indicate that absence of CGA can be new and important ultrasound marker for cervical maturation.…”

Cervical gland area as an ultrasonographic marker for preterm delivery

Abstract: The results seem to indicate that the absence of CGA can be a new and important ultrasound marker for SPTD, to be confirmed by future multicenter investigations.
