Prophylactic cerclage was performed in women with an obstetric history of cervical insufficiency. After cerclage, all participants underwent routine transvaginal cervical measurement every 2\u20134\u2009weeks until 32\u201334\u2009weeks of gestation. Trajectory patterns of changes in cervical length were identified through latent class trajectory modeling. The association of patterns with spontaneous preterm birth and pregnancy interval was analyzed by multivariable logistic regression analysis and Cox proportional hazards regression models. The specific characteristics of changes in cervical length associated with preterm birth were identified.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We involved 225 women and acquired a total of 1248 measurements of cervical length. Two distinct trajectories of cervical length change along gestation were identified: Class 1 (persistent shortening of cervix, <jats:italic>n<\/jats:italic>\u2009=\u200952 [23.11%]) and class 2 (stable cervix, <jats:italic>n<\/jats:italic>\u2009=\u2009173 [76.89%]). Women in class 1 were highly associated with spontaneous preterm birth, with a hazard ratio (95% confidence interval [CI]) of 2.00 (1.36, 2.96). The average shortening rate \u22650.24\u2009cm per week and cervical length \u22641.1\u2009cm was significantly associated with spontaneous preterm birth at different gestational age.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Serial sonographic cervical length measurements after prophylactic cerclage are valuable in predicting preterm birth.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ijgo.16041","type":"journal-article","created":{"date-parts":[[2024,11,19]],"date-time":"2024-11-19T11:12:45Z","timestamp":1732014765000},"page":"356-364","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Longitudinal change in cervical length measured after prophylactic cerclage in predicting spontaneous preterm birth"],"prefix":"10.1002","volume":"169","author":[{"given":"Min","family":"Lv","sequence":"first","affiliation":[{"name":"Department of Obstetrics, Women's Hospital, School of Medicine Zhejiang University  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neng","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women's Hospital, School of Medicine Zhejiang University  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danxiao","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women's Hospital, School of Medicine Zhejiang University  Hangzhou China"},{"name":"Department of Obstetrics Cixi People's Hospital Medical and Health Group  CiXi Zhejiang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liping","family":"Qiu","sequence":"additional","affiliation":[{"name":"Department of Obstetrics Huzhou Maternity and Child Health Care hospital  Zhejiang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danqing","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women's Hospital, School of Medicine Zhejiang University  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0782-4462","authenticated-orcid":false,"given":"Qiong","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women's Hospital, School of Medicine Zhejiang University  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,11,19]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(16)31593-8"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/aog.0000000000000228"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jogc.2018.08.009"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-828X.2012.01412.x"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0029-7844(98)00568-7"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/1471-0528.17003"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/14767050802613199"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/aog.0000000000004479"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2008.03.033"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1067\/s0002-9378(03)00656-2"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12884-016-0866-3"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0039-1688480"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0029-7844(00)00924-8"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajogmf.2023.100987"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2017-020683"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000443276.68274.cc"},{"key":"e_1_2_11_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.14742"},{"key":"e_1_2_11_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/s2215-0366(16)00097-3"},{"key":"e_1_2_11_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.2659"},{"key":"e_1_2_11_21_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/16.1.172"},{"key":"e_1_2_11_22_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.2002.00788.x"},{"key":"e_1_2_11_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijgo.2014.10.011"},{"key":"e_1_2_11_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2016.04.027"},{"key":"e_1_2_11_25_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.2773"},{"key":"e_1_2_11_26_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2024.4592"},{"key":"e_1_2_11_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.27614"},{"key":"e_1_2_11_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0002-9378(03)00779-8"}],"container-title":["International Journal of Gynecology &amp;
