“…In a study recently conducted by Gültekin et al ., it has been shown that decreased tissue elasticity, measured by elastosonography, had effects on the operative parameters of bleeding and operation times 20 . Besides, we have reported that placental elastography can predict the degree of intraoperative bleeding that occurs during a C‐section 21 …”

“…20 Besides, we have reported that placental elastography can predict the degree of intraoperative bleeding that occurs during a C-section. 21 Ultrasound elastography provides information about the mechanical properties of tissues. Elasticity refers to a tissue's ability to deform when an external force is applied and then restore itself to its original size and shape when that force is removed.…”

Aim We aimed to evaluate placental elasticity for the short‐time prediction of delivery in cases of threatened preterm labor (TPL). Methods We performed a prospective study with consented pregnant women diagnosed with TPL (24th to 34th gestational week). According to the birth time, the patients were grouped into two groups, whether the delivery happened in the following first week or not. We compared the placental strain ratio (PSR) values between these two groups. Results A total of 108 pregnant women divided into two groups according to the delivery time were enrolled in our study. The pregnant women who had a delivery in 1 week after hospitalization have increased PSR values when compared to those who have not delivered within 1 week (P < 0.001). Multivariate logistic regression analysis showed that cervical length and PSR were significantly associated with delivery in 1 week after hospitalization. When the cervical length was entered as a covariate (control) variable, PSR was significantly associated with delivery time (B = 0.504, odds ratio: 1.655, 95% confidence interval: 1.339–2.045, P < 0.001). A PSR value of 4.04 had a sensitivity of 77.78% and a specificity of 87.04% in terms of short‐time prediction of the delivery time, in the receiver–operator curves analysis to determine the cut‐off point PSR value. Conclusion Elastography may contribute to predict the delivery time in high‐risk pregnants with TPL.

“…[8][9][10][11] Placental elasticity is also being studied to predict the time of delivery in threatened preterm labour and on intraoperative bleeding in post-caesarean pregnant women. 12,13 The first report on cervical elastography during pregnancy was published in 2007. 7 Two types of cervical elastography have been developed for quantitative determination of stiffness of pregnant cervixstrain elastography and shear wave elastography.…”

Objectives: The aim of the study was to evaluate the stiffness of cervix and determine its significance in predicting successful outcome of induction of labour. The primary objective was to determine the differences in elastography indices of different areas of cervix between the outcome groups of successful and failed induction of labour. A secondary objective was to find out the correlation of these elastography indices with Bishop’s score and cervical length. Methods: This was a prospective, observational study conducted over a period of 6 months on pregnant women admitted in the labour room for induction of labour. Establishment of adequate regular uterine contractions – at least three contractions lasting 40–45 s in a 10-min period – was taken as end point for successful outcome of induction of labour. Even after 24 h of initiation of induction of labour, regular, adequate and painful uterine contractions were not established, then induction of labour was described as having failed. Prior to induction, cervical length measurement, Bishop’s scoring and elastographic evaluation of the cervix were done by stress–strain elastography. A colour map was produced from purple to red and a five-step scale – the elastography index – was used to describe the various parts of the cervix. The differences between elastography indices of different parts of cervix were estimated using Mann–Whitney U test. Correlation of the indices with cervical length and Bishop’s score was determined by Spearman’s correlation coefficient. Results: A total of 64 women were included in the study. A significant difference ( p < 0.001) was found in the elastography index of internal os between the two outcome groups of success (1.76 ± 0.64) and failure (0.54 ± 0.18). However, the elastography index of central cervical canal, external os, anterior lip and posterior lips did not differ significantly across the outcome groups. A significant positive correlation was found between elastography index of internal os and cervical length (Spearman’s correlation coefficient, r = 0.441, p < 0.001) and between elastography index of external os and cervical length ( r = 0.347, p = 0.005), whereas a negative correlation was seen between elastography index of external os and Bishop’s score ( r = −0.270, p = 0.031). Conclusion: Elastography index of internal os can be used to predict outcome of induction of labour. Cervical elastography is a promising new technique for cervical consistency assessment. Further larger studies are required to determine some cut-off point for elastography index of internal os in prediction of outcome of induction of labour and to strongly establish the usefulness of cervical elastography for pregnancy management, preventing preterm delivery and establishment of cut-off points to determine successful induction.
