Abstract
BACKGROUND Cervical cerclage is the only effective treatment for cervical insufficiency, effectively preventing late miscarriage and preterm birth. The effectiveness and safety of emergency cervical cerclage (ECC) as an emergency treatment when the cervix is already dilated or when there is protrusion of the fetal membranes into the vagina remain controversial, especially in pregnancies at 24-28 weeks when the fetus is viable. There is still no consensus on whether emergency cervical cerclage should be performed in such cases. PURPOSE To investigate the effectiveness and safety of emergency cervical cerclage in singleton pregnant women at 24-28 weeks of gestation. METHODS This study employed a single-center prospective cohort design, enrolling singleton pregnant women at 24-28 weeks of gestation with ultrasound or physical examination indicating cervical dilation or even membrane protrusion. Emergency cervical cerclage was compared with conservative treatment. The primary endpoints included a comprehensive assessment of perinatal pregnancy loss, significant neonatal morbidity, and adverse neonatal outcomes. Secondary endpoints included prolonged gestational age, preterm birth, neonatal hospitalization rate, premature rupture of membranes, and intrauterine infection/chorioamnionitis. RESULTS From June 2021 to March 2023, a total of 133 pregnant women participated in this study, with 125 completing the trial, and were allocated to either the Emergency Cervical Cerclage (ECC) group (72 cases) or the conservative treatment group (53 cases) based on informed consent from the pregnant women. The rate of adverse neonatal outcomes was 8.33% in the ECC group and 26.42% in the conservative treatment (CT) group, with a statistically significant difference (P = 0.06). There were no significant differences between the two groups in terms of perinatal pregnancy loss and significant neonatal morbidity. The conservative treatment group had a mean prolonged gestational age of 63.0 (23.0, 79.5) days, while the ECC group had 84.0 (72.5, 89.0) days, with a statistically significant difference between the two groups (P < 0.001). Compared with CT group, the ECC group showed a significantly reduced incidence of preterm birth before 28 weeks, 32 weeks, and 34 weeks, with statistical significance (P = 0.046, 0.007, 0.001), as well as a significantly decreased neonatal hospitalization rate (P = 0.013, 0.031). Additionally, ECC treatment did not increase the risk of preterm premature rupture of membranes or intrauterine infection/chorioamnionitis, with no statistically significant differences (P = 0.406, 0.397). CONCLUSION In singleton pregnant women with cervical insufficiency at 24-28 weeks of gestation, emergency cervical cerclage can reduce adverse neonatal pregnancy outcomes, effectively prolong gestational age, decrease preterm births before 28 weeks, 32 weeks, and 34 weeks, lower neonatal hospitalization rates, and does not increase the risk of preterm premature rupture of membranes or intrauterine infection/chorioamnionitis.

Abstract
BACKGROUND To evaluate the use and effect of cervical stitch cerclage, pessary, and progesterone on pregnancy outcome in mothers of very low birth weight infants (VLBWI) born<32 weeks of gestation in the German Neonatal Network (GNN). METHODS The GNN is a population-based cohort study enrolling VLBWI since 2009. We included 575 neonates from 424 mothers into our analysis, who were born between 2015 and 2019, after prenatal intervention with cerclage, pessary, progesterone or a combination between 20/0 to 25/0 weeks of gestation to prevent preterm birth. Median intervention-to-birth interval was the primary endpoint. RESULTS 231 of 424 pregnant women had a cerclage only (54.5%), 76 women a pessary only (17.9%), and 27 were prescribed progesterone only (15.3%). The most common combination treatment (>1 intervention group) was cerclage plus progesterone (n=27), followed by cerclage plus pessary (n=13). The median intervention-to-birth interval for the whole cohort was 24 days (IQR 19.0 days). The earlier the intervention was started, the longer the intervention-to-birth interval lasted: When started at 20 weeks, the interval was 34 days in contrast to 11.5 days, when started at 25 weeks. The >1 group was born at a significantly higher median GA with 27.0 weeks (IQR 2.9 weeks) and a higher median birth weight of 980 g (IQR 394 g) accordingly. CONCLUSION We propose that the earliest possible start of intervention leads to the most efficient pregnancy prolongation.

Abstract
INTRODUCTION Bacteria are the most common pathogens implicated in ascending infections in patients with cervical insufficiency. However, Candida albicans is a rare and serious cause of intra-amniotic infection that should be considered on the differential diagnosis. Upon diagnosis following cerclage placement, patients are generally advised to undergo immediate cerclage removal and discontinuation of the pregnancy due to the high risk of maternal and fetal morbidity. However, some patients decline and instead elect to continue the pregnancy with or without treatment. Limited data exist to guide management of these high-risk patients. CASE PRESENTATION We describe a case of previable intra-amniotic C. albicans infection diagnosed following physical examination-indicated cerclage placement. The patient declined pregnancy termination and subsequently underwent systemic antifungal therapy as well as serial intra-amniotic fluconazole instillations. Fetal blood sampling confirmed transplacental transfer of maternal systemic antifungal therapy. The fetus delivered preterm and without evidence of fungemia, despite persistently positive amniotic fluid cultures. CONCLUSION In a well-counseled patient with culture-proven intra-amniotic C. albicans infection declining termination of pregnancy, multimodal antifungal therapy in the form of systemic and intra-amniotic fluconazole administration may prevent subsequent fetal or neonatal fungemia and improve postnatal outcomes. KEY POINTS · Candida is an uncommon cause of intra-amniotic infection in the setting of cervical insufficiency.. · Multimodal antifungal therapy may prevent fetal fungemia related to intra-amniotic Candida infection.. · Fetal blood sampling confirmed transplacental passage of fluconazole after maternal administration..

BMC Pregnancy Childbirth 2024; 24:324. [PMID: 38671377 PMCID: PMC11046802 DOI: 10.1186/s12884-024-06509-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Accepted: 04/11/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND The leading hypothesis of the pathogenesis of cervical insufficiency suggests a role of cervical inflammation. Urogenital tract infections could play a causative role in this process. To test this hypothesis in women with a cervical cerclage, we aimed to retrospectively examine the relationship between gestational age (GA) at delivery and positive urogenital cultures. METHODS This single center retrospective study reviewed the records of all women with a singleton pregnancy that underwent cervical cerclage (n = 203) between 2010 and 2020 at the University Hospital of Leuven, Belgium. Transvaginal cerclages were categorized as history indicated (TVC I, n = 94), ultrasound indicated (TVC II, n = 79) and clinically indicated (TVC III, n = 20). Additionally, ten women received transabdominal cerclage (TAC). Urogenital cultures (vaginal and urine) were taken before and after cerclage with 4-week intervals. Urogenital cultures were reported 'positive' if urine and/or vaginal cultures showed significant growth of a microorganism. Treatment decision depended on culture growth and clinical presentation. The primary aim was to evaluate the association between the urogenital culture results and the GA at delivery, for each of the cerclage groups. Secondarily, to investigate the effect of antibiotic treatment of positive cultures on GA at delivery. RESULTS Positive pre-cerclage urogenital cultures were associated with lower GA at delivery in TVC III (positive culture 26w4d ± 40d vs. negative 29w6d ± 54d, p = 0.036). For TVC I, GA at delivery was longer when pre-cerclage urogenital cultures were positive (positive culture 38w0d ± 26d vs. negative 35w4d ± 42d, p = 0.035). Overall post-cerclage urogenital cultures status was not associated with a different GA at delivery. Treating patients with pre- or post-cerclage positive urogenital cultures did also not change GA at delivery. CONCLUSION Positive urogenital cultures taken before clinically indicated cerclage intervention may be associated with lower GA at delivery. However, there seems to be no benefit of antibiotic treatment or routine urogenital cultures during follow-up of asymptomatic women after cerclage placement.

Abstract
OBJECTIVE This study aimed to describe the pregnancy outcomes of a case series of patients with probable cerclage failure who received repeat cerclage (RC) with potential indications. METHODS We retrospectively collected a case series of 55 singleton pregnancies with RC from 2019 to 2022 in Shanghai, China. All included women provided written informed consent, and the study was approved by the ethics committees of the two hospitals. We compared pregnancy outcomes between pregnancies with RC for different indications. RESULTS Among the case series, nine patients underwent RC for the indication of protruding membranes below the previous suture loop (group A), and the other 46 patients for painless cervix dilation (group B). Gestational age at delivery was shorter in group B than in group A (30.7 vs 37.6 weeks, P = 0.009). Rates of preterm birth <32 weeks (63.0% vs 22.2%, P = 0.033) and < 37 weeks (76.1% vs 33.3%, P = 0.002) were significantly higher in group B than in group A. Of the 46 patients who underwent RC for painless cervical dilation, 28 had cervical dilation of 1 to 2 cm (group C) and the other 18 had cervical dilation of 3 to 6 cm (group D). The gestational age at delivery was shorter in group D than in group C (27.4 vs 31.5 weeks, P = 0.037). However, rates of preterm birth <32 or <37 weeks were similar between the groups. CONCLUSION RC may constitute a rescue strategy for patients with probable cerclage failure. Protrusion of membranes below the cerclage loop or cervical dilation <3 cm may be an indicator of better pregnancy outcome.

Abstract
OBJECTIVE To study the guiding significance of medical history on laparoscopic and vaginal cervical cerclage in the treatment of cervical incompetence and its influence on pregnancy outcome. METHODS A total of 53 cases by laparoscopic abdominal cervical cerclage (LAC group) before pregnancy and 73 cases by transvaginal cervix cerclage (TVC group) at 12-14 weeks of pregnancy were collected. Multivariate logistic regression analysis was performed on the influencing factors of delivery gestational weeks. Furthermore, the gestational weeks after cervical cerclage were compared between the two groups with high- and low-risk grades. RESULTS The number of previous uterine cavity operations in LAC group was more than that TVC group, and the costs of operation were more than TVC group. At the same time, the hospitalization days and operation time were longer than those in TVC group, and the delivery rate of cesarean section was higher than TVC group, but the total hospitalization times were less than TVC group (P < 0.05). The rate of delivery before 34 weeks of pregnancy and the incidence of premature rupture of membranes or premature labor in LAC group were lower than those in TVC group (P < 0.05). In TVC group, the increased number of prior PTB or STL and the history of cervical cerclage failure would increase the risk of premature delivery before 34 weeks of pregnancy. There was no increased risk of preterm delivery before 34 weeks of pregnancy in LAC group (P > 0.05). According to the risk level, in the high-risk group, the delivery rate of LAC group at gestational weeks < 37 weeks, < 34 weeks and < 28 weeks was lower than that of TVC group. CONCLUSION Laparoscopic cervical cerclage might be more effective in preventing premature delivery before 34 weeks of gestation, and its influence on delivery gestational weeks was not affected by related medical history. For high-risk patients with the history of prior PTB or STL and failed cerclage, laparoscopic cervical cerclage might be more effective than vaginal cervical cerclage in preventing extremely preterm before 28 weeks, premature delivery before 34 weeks and premature delivery before 37 weeks. Therefore, our limited experience suggested that LAC can be a recommended option for patients with high-risk history.

Abstract
OBJECTIVE Pregnancy outcomes of individuals receiving cervical cerclage when the cervix is dilated are not well known. We sought to examine preterm birth rates after ultrasound or physical examination-indicated cerclage placement according to the degree of cervical dilation. STUDY DESIGN This was a retrospective cohort study of individuals with singleton pregnancies undergoing ultrasound or physical examination-indicated cerclage before 240/7 weeks of gestation from 2004 to 2018. Individuals were categorized based on the degree of cervical dilation at the time of cerclage. Our primary outcome was preterm delivery at less than 37 weeks of gestation. Multivariable logistic regression was performed to calculate adjusted odds ratios (aOR) with 95th confidence intervals (95% CI), controlling for predefined covariates. RESULTS Of 147 individuals undergoing ultrasound or physical examination-indicated cerclage, 90/147 (61%) had a closed or 0.5 cm dilated cervix at the time of cerclage placement, 45/147 (31%) had a cervical dilation of 1 to 2.5 cm, and 12/147 (8%) had a cervical dilation of 3 to 4 cm at the time of placement. Individuals with a cervical dilation of 1 to 2.5 cm compared with those who had a closed cervix did not have increased odds of preterm delivery (58 vs. 42%; aOR: 1.95; 95% CI: 0.93-4.07). However, individuals with a cervical dilation of 3 to 4 cm compared with individuals who had a closed cervix had significantly increased odds of preterm delivery (75 vs. 42%; aOR: 4.33; 95% CI: 1.05-17.77). CONCLUSION The rate of preterm birth increases with increasing cervical dilation at the time of cerclage placement. However, individuals who have a cerclage placed when the cervix is 1 to 2.5 cm can achieve an outcome that is not significantly different from those who had a cerclage placed when the cervix is closed. KEY POINTS · Time from cerclage placement to delivery decreases as cervical dilation increases.. · Individuals 1 to 2.5 cm dilated at the time of cerclage can achieve a favorable outcome.. · A cervical dilation of ≥3 cm at cerclage placement was associated with extreme prematurity..

Abstract
AIM The study aimed to identify predictive risk factor to identify high-stage histological chorioamnionitis (HCA) in pregnancies with cervical incompetence (CIC). METHODS A retrospective cohort study was conducted by including 116 pregnant women with cervical incompetence that required prophylactical and therapeutical cerclage. The histopathology examination on placenta was conducted with informed patient consent. All the cases included in this study were divided based on the severity degree of HCA. The demographic characteristic and the parameters related to maternal and fetal outcome were all analyzed. Besides, perioperative parameters of cerclage, including cervical length, cervical morphology, and laboratory indexes were also compared between two groups. Univariate and multivariate logistic regression analysis were used to determine the risk factor of severe chorioamnionitis. RESULTS Severe HCA was significantly associated with cervical morphology, cerclage indication, cerclage type, and cervical length measured via ultrasound and vaginal examination. After adjusted for confounders, V-type funneling and short cervix was indicated as independent risk factors of severe HCA by multivariate logistic regression analysis, respectively. CONCLUSIONS V-type funneling and short cervix may indicate the elevated risk of high-stage HCA. Due to the negative outcomes related with high-stage HCA, appropriate prenatal treatment would improve the pregnancy outcomes in cerclaged population. To facilitate postpartum treatment, placental histological examination should be routinely recommended to identify the high-stage HCA, especially in high risk pregnancies.

Noninvasive factors predicting the maintenance of pregnancy for more than 4 weeks after rescue cerclage in singleton pregnancies with cervical dilatation and prolapsed membrane. Medicine (Baltimore) 2024; 103:e37690. [PMID: 38552048 PMCID: PMC10977542 DOI: 10.1097/md.0000000000037690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 03/01/2024] [Indexed: 04/02/2024] Open
Abstract
Studies on noninvasive factors and predicting the maintenance of pregnancy, and those comparing the usefulness of these factors with invasive amniotic fluid markers in predicting the maintenance of pregnancy following rescue cerclage, are lacking. Therefore, this study aimed to determine whether C-reactive protein (CRP) levels, White blood cell (WBC) count, absolute neutrophil count (ANC), and platelet-to-lymphocyte ratio (PLR) in maternal blood, which are noninvasive and readily available clinical markers, can predict the maintenance of pregnancy following rescue cerclage in patients with cervical insufficiency (CI). A total of 142 singleton pregnant women (15-28 wk) who underwent rescue cerclage for CI were retrospectively evaluated. The interleukin (IL)-6 concentration in the amniotic fluid; CRP levels, WBC count, ANC, and PLR in the maternal peripheral blood; and degree of cervical dilatation were evaluated before cerclage. The primary outcome was whether the pregnancy was maintained for >4 weeks after rescue cerclage. Among the 142 patients, prolonged pregnancy for >4 weeks following emergent cerclage was observed in 107 (75.35%), while 35 (24.65%) gave birth within 4 weeks. This study demonstrated that the degree of cervical dilatation at diagnosis; WBC count, ANC, and CRP levels in the maternal peripheral blood; and IL-6 concentration in the amniotic fluid significantly differed between the successful and failure groups (all P < .05). The area under the curve (AUC) of the amniotic fluid IL-6 concentration was .795 for the prediction of spontaneous preterm birth within 4 weeks after rescue cerclage. Additionally, the AUC of the CRP level, cervical dilatation, WBC count, ANC, and PLR were .795, .703, .695, .682, and .625, respectively. These findings suggest that the preoperative CRP levels can be considered a useful noninvasive marker comparable to amniotic fluid IL-6 concentration for identifying pregnant women with CI at high risk of spontaneous preterm birth following rescue cerclage.

Abstract
Purpose: Cervical insufficiency is a significant risk factor for preterm birth and miscarriage during the second trimester; cervical cerclage is a treatment option. This study seeks to evaluate the predictive roles of various clinical factors and to develop predictive models for immediate and long-term outcomes after rescue cerclage. Methods: We conducted a multicenter retrospective study on patients who underwent rescue cerclage at 14 to 26 weeks of gestation. Data were collected from the Electronic Medical Record systems of participating hospitals. Outcomes were dichotomized into immediate failure (inability to maintain pregnancy for at least 48 hours post-cerclage, gestational latency < 2 days) and long-term success (maintenance of pregnancy until at least 28 weeks of gestation). Clinical factors influencing these outcomes were analyzed. Results: The study included 98 patients. Immediate failure correlated with longer prolapsed membrane lengths, elevated C-reactive protein levels at admission, and extended operation time. The successful maintenance of pregnancy until at least 28 weeks was associated with earlier gestational age at diagnosis, negative AmniSure test results, longer lengths of the functional cervix, and smaller cervical dilatation at the time of cerclage. Binary logistic regression models for immediate failure and long-term success exhibited excellent and good predictive abilities, respectively (AUROC = 0.912, 95% CI: 0.834-0.989; and AUROC = 0.872, 95% CI: 0.788-0.956). Conclusion: The developed logistic regression models offer a valuable tool for the prognostic assessment of patients undergoing rescue cerclage, enabling informed clinical decision-making.

Abstract
RATIONALE To report a peculiar case of vaginal delivery of a triplet after emergency transvaginal cerclage and to find a way to optimize some extreme situations encountered in clinical practice after evaluating feasibility. PATIENT CONCERNS A 33-year-old gravida 6, para 0050 woman at 21 + 6 weeks of gestation was referred to the obstetric department for opening of the cervical canal. An emergency McDonald cerclage was performed at 22 weeks of gestation after a comprehensive assessment, and the pregnancy ended with vaginal delivery at 24 + 6 weeks of gestation. The postpartum period was normal, and the newborns were discharged to home care after treatment in the neonatal intensive care unit. INTERVENTIONS After discussing the risks, the patient requested emergency transvaginal McDonald cerclage at 22 weeks of gestation. OUTCOMES Emergency McDonald cerclage was performed at 22 weeks of gestation, and the pregnancy ended with vaginal delivery at 24 + 6/25 weeks of gestation, successfully prolonging gestation by 20/21 days. The postpartum period had no exceptional circumstances, and newborns were discharged to home care after treatment in the neonatal intensive care unit for 104/98/104 days. LESSONS Emergency cerclage seems to be impossible in multiple pregnancies. However, in this case, after a comprehensive assessment, it was feasible to extend the gestational age by emergency cerclage, and prompt and accurate evaluation is important to avoid complications and individualize the following management. In this case, we may find a way to optimize some extreme situations encountered in clinical practice and offer a glimmer of hope for families challenged with multiple pregnancies at risk of preterm delivery. However, more high-quality studies are needed to prove the effectiveness and safety of emergency cerclages in triplets.

Abstract
OBJECTIVE To investigate the efficacy of transvaginal cerclage in twin pregnancies with cervical shortening, and to narrow the threshold cervical length for transvaginal cerclage. METHODS This is a prospective cohort study and 177 twin pregnancies with asymptomatic cervical dilatation or cervical length of 15 mm or less between 16+0 and 25+6 weeks of pregnancy were included. Patients independently chose either transvaginal cerclage (n = 129) or no cerclage treatment (n = 48) after being consulted on the risk and potential benefit of transvaginal cerclage. The primary outcome measures were gestational age at delivery and neonatal survival rate. RESULTS Compared with the no cerclage group, the cerclage group exhibited a higher gestational age at delivery (32.1 ± 4.5 vs 28.3 ± 6.2 weeks, P < 0.001) and a higher neonatal survival rate (86.4% vs 47.9%, P < 0.001). Subgroup analysis showed that in twin pregnancies with cervical dilatation or cervical length less than 10 mm, the cerclage group had significantly higher gestational age at delivery (31.3 ± 4.6 vs 23.4 ± 4.3 weeks, P < 0.001) and a higher neonatal survival rate (123 [85.4%] vs 4 [9.1%], P < 0.001) than the no cerclage group, but in twins when cervical length was 10-15 mm, the two measures were similar between the two groups. CONCLUSION Transvaginal cerclage may provide benefits for twins when cervical dilatation or cervical length is less than 10 mm, but its efficacy might not extend to twins when the cervical length is 10-15 mm. Further evidence is needed to confirm the efficacy of transvaginal cerclage for twin pregnancies with a short cervix.

Abstract
OBJECTIVE To evaluate the value of transvaginal ultrasound parameters before and after cerclage in twins in predicting spontaneous preterm birth (sPTB) before 28+0 weeks. METHODS We retrospectively studied the medical records of twin-pregnant women who underwent ultrasound-indicated cerclage between January 2016 and February 2022 at our hospital. Recorded transvaginal ultrasound images before and after cerclage were reassessed for cervical length (CL), uterocervical angle (UCA), funneling, and sludge. Multivariate logistic and Cox regression analyses were performed to identify the independent risk factors associated with sPTB before 28 weeks. RESULTS A total of 69 women were included. Among them, 17 women (24.64%) delivered before 28 weeks of age. Regression analysis revealed a significant association of post-cerclage CL, UCA, white blood cell (WBC) count, and gestational age (GA) at cerclage with sPTB before 28 weeks. The area under the curve of these predictors was 0.938 (95% confidence interval, 0.882-0.994; p < .001), with a sensitivity of 88.2%, specificity of 92.3%, positive predictive value of 78.9%, and negative predictive value of 96.0%. Cox analysis showed that post-cerclage UCA was an independent risk factor affecting the cerclage-to-delivery interval (hazard ratios, 1.026; 95% confidence interval (CI), 1.004-1.048; p = .019). CONCLUSIONS The combination of post-cerclage CL, UCA, WBC count, and GA at cerclage showed good performance in predicting sPTB at <28 weeks in twin pregnancy. Post-cerclage UCA is also associated with pregnancy latency. We found that post-cerclage cervical ultrasound may be useful to predict preterm birth before 28 weeks in twins who undergo ultrasound-indicated cerclage.

Abstract
Twins represent 3.2% of all live births. However, they account for 20% of all preterm deliveries, 60% delivering <37 weeks, 10.7% <32 weeks, and 5 times higher risk of infant death. Risk factors for preterm birth (PTB) include the history of preterm delivery, monochorionic twins, short cervical length, and cervical surgery. Transvaginal cervical length <24 weeks is the best tool to predict PTB. Only vaginal progesterone in women with transvaginal cervical length <25 mm and physical exam indicated cerclage in women with cervical dilation >1 cm have shown a significant decrease in PTB and improvement in neonatal outcomes.

Abstract
Objective: To investigate the clinical efficacy of modified Shirodkar transvaginal cervical cerclage (TVCC) in the treatment of cervical insufficiency (CI) and its impact on maternal and fetal outcomes. Methods: The clinical data of 218 pregnant women with CI admitted to Fu Xing Hospital, Capital Medical University from January 1, 2015 to August 31, 2021 was retrospectively analyzed. According to different surgical approaches, they were divided into modified Shirodkar TVCC treatment during pregnancy (TVCC group, 108 cases) and non-pregnant women underwent laparoscopic cervical cerclage (LACC) treatment (LACC group, 110 cases). The clinical data and pregnancy outcomes of the two groups were compared. Furthermore, the two groups of pregnant women were stratified according to cervical length (CL) to explore the effects of the two surgical methods on the pregnancy outcomes of CI women with different CL. Results: (1) Related indicators before and during cerclage: there were no complications such as massive hemorrhage, bladder injury and anesthesia accident in the two groups of pregnant women during cerclage. Compared with the LACC group, TVCC group had longer preoperative CL [(2.3±0.6) vs (2.7±0.6) cm], more intraoperative blood loss [(7.5±0.5) vs (14.4±1.4) ml] and longer hospital stay [(6.0±0.1) vs (7.3±0.4) day]. However, the operation time was shorter [(42.9±1.6) vs (25.9±1.4) minute] and the hospitalization cost was less [(9 912±120) vs (5 598±140) yuan], and the differences were statistically significant (all P<0.05). (2) Pregnancy outcomes: live birth rates were 95.4% (103/108) in the TVCC group and 96.4% (106/110) in the LACC group, showing no significant difference between the two groups (χ2=2.211, P=0.232). The preterm birth rate (12.0%, 13/108) in the TVCC group was higher than that in the LACC group (7.3%, 8/110), the neonatal birth weight was lower than that in the LACC group [(3 006±96) vs (3 225±42) g], and the proportion of low birth weight infants was higher than that in the LACC group [15.5% (16/103) vs 1.9% (2/106)], and the differences were statistically significant (all P<0.05). (3) Stratified analysis of CL: for pregnant women with CL<2.0 cm, the miscarriage rate of the TVCC group was higher than that of the LACC group (2/9 vs 3.0%), and the live birth rate was lower than that of the LACC group (7/9 vs 97.0%), and the differences were statistically significant (all P<0.05). For CL 2.0-<2.5 cm, 2.5-<3.0 cm, CL≥3.0 cm, there were no statistically significant differences in preterm birth rate and live birth rate between the two groups (all P>0.05). Conclusions: Modified Shirodkar TVCC is simple and easy to operate, which significantly reduces the cesarean section rate and medical cost compared with LACC, and there is no significant difference in the live birth rate. When there is inevitable late abortion, laparoscopic cerclage removal does not need to be performed again, which could reduce the second operation and is worthy of clinical application.

Abstract
OBJECTIVES Primary outcomes were to determine; 1) the desire for more patient information from healthcare professionals on preterm birth (PTB) prevention 2) the desire for PTB screening surveillance or participation in research or 3) the acceptability of transvaginal ultrasound (TVUS) or vaginal examinations to predict spontaneous PTB. METHODS A 19-question, piloted, self-administered survey was completed by unselected pregnant women in a tertiary maternity hospital in Dublin, Ireland. Data was collected to include maternal socio-demographics, past obstetric history, and current pregnancy details, in addition to views and preferences on PTB screening and preventative treatments. Statistical analysis to include binary and multinomial regression was performed by IBM SPSS Statistics for Windows (Version 29.0). RESULTS 277 women completed the study survey. 9.4% of women had attended the preterm birth surveillance clinic (PSC). 75.1% of respondents indicated a preference for more information from healthcare professionals about PTB. 65% reported that TVUS and vaginal examinations were acceptable in pregnancy. The acceptability of antenatal examinations was significantly influenced by ethnicity; white European (OR 2.58, CI 1.12-5.95, p = 0.003) and Asian (OR 3.39, CI 1.18-9.67, p = 0.02). Discomfort (25.3%) and vaginal bleeding (11.9%) were the most frequently reported concerns about TVUS. 95.7% of unselected women indicated that they would accept treatment to prevent PTB. Vaginal progesterone (53.8%) was preferred treatment compared to cervical cerclage (15.9%) or cervical pessary (16.6%). 55.6% of respondents stated they attend or wish to attend for additional appointments or research opportunities for PTB screening. Women with a previous PTB or second trimester miscarriage were more likely to attend or wish to attend for PTB screening (OR 3.23, CI 1.34-7.79, p = 0.009). CONCLUSION PTB is an important healthcare priority for pregnant women in Ireland. However, women require more information, counselling and reassurance about the utility and safety of TVUS in PSCs.

Changes in cervical elastography, cervical length and endocervical canal width after cerclage for cervical insufficiency: an observational ultrasound study. BMC Pregnancy Childbirth 2023; 23:750. [PMID: 37875844 PMCID: PMC10594665 DOI: 10.1186/s12884-023-06071-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 10/16/2023] [Indexed: 10/26/2023] Open
Abstract
BACKGROUND We previously demonstrated that pregnant women with a history of cervical insufficiency had a softer anterior cervical lip, shorter cervical length and wider endocervical canal in the first trimester. The aim of this study was to investigate changes in cervical elastography, cervical length, and endocervical canal width in the second trimester after cerclage, and further discuss whether these ultrasound parameters are predictive of preterm delivery. METHODS This was a secondary analysis of cervical changes in singleton pregnancies after cerclage from January 2016 to June 2018. Cervical elastography, cervical length, and endocervical canal width were measured during the second trimester in the cervical insufficiency group and control group without cervical insufficiency. Strain elastography under transvaginal ultrasound was used to assess cervical stiffness and presented as percentage (strain rate). RESULTS Among the 339 pregnant women enrolled, 24 had a history of cervical insufficiency and underwent cerclage. Both anterior and posterior cervical lips were significantly softer in the cervical insufficiency group even though they received cerclage (anterior strain rate: 0.18 ± 0.06% vs. 0.13 ± 0.04%; P = 0.001; posterior strain rate: 0.11 ± 0.03% vs. 0.09 ± 0.04%; P = 0.017). Cervical length was also shorter in the cervical insufficiency group (36.3 ± 3.6 mm vs. 38.3 ± 4.6 mm; P = 0.047). However, there was no significant difference in endocervical canal width between the two groups (5.4 ± 0.7 mm vs. 5.6 ± 0.7 mm; P = 0.159). Multivariate logistic regression analysis also revealed significant differences in anterior cervical lip strain rate (adjusted odds ratio [OR], 7.32, 95% confidence interval [CI], 1.70-31.41; P = 0.007), posterior cervical lip strain rate (adjusted OR, 5.22, 95% CI, 1.42-19.18; P = 0.013), and cervical length (adjusted OR, 3.17, 95% CI,1.08-9.29; P = 0.035). Among the four ultrasound parameters, softer anterior cervical lip (P = 0.024) and shorter cervical length (P < 0.001) were significantly related to preterm delivery. CONCLUSIONS Cervical cerclage can prevent widening of the endocervical canal, but not improve cervical elasticity or cervical length. Measuring anterior cervical elastography and cervical length may be valuable to predict preterm delivery.

Abstract
PURPOSE To determine the predictive value of maternal White Blood Cells (WBC), neutrophils, and C-Reactive Protein (CRP) for diagnosing Histological Chorioamnionitis (HCA) among women with Preterm Premature Rupture of Membranes (PPROM) who underwent cervical cerclage. METHODS A retrospective cross-sectional study was conducted among women with singleton pregnancy and PPROM, who underwent cervical cerclage during 2018-2020. RESULTS A total of 55 eligible women were included in the final analysis, including 36 (61.02%) cases with HCA and 19 (38.98%) without HCA. Women with HCA had higher WBC count (12.31 ± 2.80) × 109/L and neutrophil count (9.67 ± 2.90)×109/L than those without HCA (10.35 ± 2.53) × 109/L and 7.82 ± 2.82 × 109/L, respectively) (both p < 0.05). The cut-off value of WBC count at 10.15×109/L was found to be the most effective in identifying HCA, with an Area Under Curve (AUC) of 0.707 (95% CI: 0.56-0.86; p = 0.012), sensitivity of 86.11%, specificity of 57.90%, Positive Predictive Value (PPV) of 79.49%, Negative Predictive Value (NPV) of 68.75%, and Youden index of 0.44. The combination of WBC + neutrophil had a slightly higher (AUC = 0.711, 95% CI: 0.57-0.86; p = 0.011), specificity (68.42%), and PPV (81.25%), but lower sensitivity (72.22%), than the WBC count alone. A cut-off value of neutrophil at 7.46 × 109/L was effective in identifying HCA, with an AUC of 0.689 (95% CI: 0.53-0.84; p = 0.022). DISCUSSION Combination use of WBC+neutrophil was found to be the most accurate predictor of HCA among women with PPROM after surgery of cervical cerclage.

Abstract
BACKGROUND To identify the effect and optimal time of cervical cerclage in asymptomatic twin pregnancies with cervical shortening or dilation. METHODS This observational retrospective study enrolled all women with asymptomatic twin pregnancies who were diagnosed with asymptomatic cervical shortening or dilation at the Second Affiliated Hospital of Wenzhou Medical University between 2010 and 2022. Women included were allocated into the cerclage group (n = 36) and the no cerclage group (n = 22). The cerclage group was further divided into the cerclage group (< 24 weeks group) and the cerclage group (24-28 weeks group) according to the time of cerclage. The no cerclage group was further divided into no cerclage group (< 24 weeks group) and no cerclage group (24-28 weeks group) according to the time of ultrasound-indicated or physical exam indicated cerclage. The rates of PTB < 24, 28, 32 and 34 weeks of gestation, maternal and neonatal outcomes were compared among the groups. RESULTS The gestational age (GA) at delivery was higher (P = 0.005) and the interval time between the presentation of the indicated cerclage and delivery was longer in the cerclage group (P < 0.001). The rates of PTB before 28, 32, and 34 weeks of gestation, caesarean section and stillbirth were lower in the cerclage group (P < 0.05). The birthweight of the twins was higher in the cerclage group (P = 0.012). Admissions to the NICU were more frequent in pregnancies with no cerclage (P = 0.008). Subgroup analysis showed that the interval time between the presentation and delivery was longer in the cerclage group (< 24 weeks) (P < 0.001). The GA at delivery and the birthweight of the twins were significantly higher in the cerclage group (< 24 weeks) (P < 0.001). No differences were found in the GA at presentation, the GA at delivery, the interval time between the presentation to delivery and birthweight between the cerclage group (24-28 weeks group) and the control group (24-28 weeks group) (P > 0.05). CONCLUSIONS Cerclage appears to prolong the GA at delivery and the interval time between the presentation to delivery, and may reduce the incidence of PTB before 28, 32 and 34 weeks of gestation and adverse perinatal outcomes in asymptomatic twin pregnancies with cervical shortening or dilation. Cerclage before 24 weeks of gestation showed longer GA at delivery, longer interval time between the presentation to delivery and higher birthweight of the twins. The GA at presentation, the GA at delivery, the interval time between the presentation to delivery and birthweight in women with cerclage at 24-28 weeks were similar to those in women without cerclage at 24-28 weeks.

Abstract
Objective: To investigate the clinical effect and the influencing factors of ultrasound-indicated cerclage and history-indicated cerclage in singleton gestation. Methods: The clinical data of 272 singleton pregnant women with cervical incompetence who underwent McDonald cervical cerclage due to medical history indication (history-indicated group) or ultrasound indication (ultrasound-indicated group) in Peking University First Hospital from January 2010 to February 2021 were retrospectively analyzed. The general clinical data and maternal and fetal outcomes were compared between the history-indicated group (141 cases) and ultrasound-indicated group (131 cases). According to the gestational age at delivery, 272 pregnant women who underwent cervical cerclage were further divided into ≥34 weeks group (225 cases) and <34 weeks group (47 cases), and the influencing factors of preterm birth before 34 weeks of gestation were analyzed. Results: (1) The median gestational age at cerclage was 16.6 weeks in the history-indicated group and 23.4 weeks in the ultrasound-indicated group, and the median gestational age extension at delivery was 21.4 weeks and 14.7 weeks, respectively, with statistically significant differences between the two groups (all P<0.05). (2) The full-term birth rate was 76.6% (108/141) in the history-indicated group and 71.0% (93/131) in the ultrasound-indicated group, the live birth rate was 97.2% (137/141) and 97.7% (128/131), and the median birth weight of live birth was 3 155 g and 3 055 g, respectively. The differences were not statistically significant (all P>0.05). Among 272 pregnant women with cervical cerclage, 265 neonates survived (97.4%, 265/272). The gestational age of 7 pregnant women who did not have live birth was ≤25 weeks of gestation (range: 19+1-25 weeks), and they were all clinically infected or confirmed chorioamnionitis or pathogenic microorganisms carrying during pregnancy, and their families gave up. The minimum birth weight of the surviving neonate was 850 g (gestational week of delivery was 26+6 weeks). (3) Univariate analysis showed that compared with ≥34 weeks group, the body mass index (BMI) of pregnant women in <34 weeks group was higher at 6-7 weeks of gestation (median: 24.5 vs 25.4 kg/m2), shorter cervical length (CL) at 1-2 weeks after surgery [(31.1±8.4) vs (26.1±11.0) mm], shorter CL at 26-28 weeks of gestation after surgery (median: 26.3 vs 16.0 mm), and higher incidence of elevated C-reactive protein (CRP) before and after surgery and before delivery. The differences were all statistically significant (all P<0.05). Multivariate logistic regression analysis showed that preterm birth before 34 weeks was negatively associated with CL at 26-28 weeks of gestation after cerclage (OR=0.902, 95%CI: 0.858-0.947; P<0.001), and was positively correlated with elevated CRP before delivery (OR=3.492, 95%CI: 1.652-7.381; P=0.001). There were no significant correlations between preterm birth and preoperative or postoperative CRP elevation, CL at 1-2 weeks after surgery, and BMI at 6-7 weeks of gestation (all P>0.05). Conclusions: Cervical cerclage for singleton pregnant women with cervical incompetence indicated by history or ultrasound both have good clinical efficacy, and there is no significant difference in maternal and fetal outcomes between the two groups. CL at 26-28 weeks of gestation and CRP before delivery are risk factors for preterm birth before 34 weeks of gestation after cervical cerclage.
