Its use at or after 24 weeks is less well characterized in twins. Materials and Methods: We describe the perinatal course of twin pregnancies that underwent cervical cerclage at 24\u201332+0 weeks at three university hospitals in South Korea between 2015 and 2024, with pregnancies treated before 24 weeks as a descriptive reference. Entry into the late group required remaining undelivered at 24 weeks without prior cerclage, so the groups do not share a common baseline and were not compared. Results: Eighteen pregnancies received cerclage at 24\u201332+0 weeks (median 26.3 weeks), and 25 received it before 24 weeks. In the late group, delivery occurred at a median of 34.1 weeks (IQR 31.7\u201335.4) after a mean cerclage-to-delivery interval of 45.8 days (95% CI 34.7\u201356.9). No fetal, neonatal, or perinatal death occurred (0 of 36 fetuses in 18 pregnancies; 95% CI 0.0\u201317.6%, calculated\u00a0on the 18 pregnancies). NICU admission was 83.3% (95% CI 62.3\u201393.8), and adverse neonatal morbidity was 55.6% (95% CI 34.2\u201375.0). Conclusions: No perinatal death was recorded in this descriptive series. Because no untreated control group was available, these findings do not establish efficacy but provide a real-world basis for future prospective controlled trials.<\/jats:p>","DOI":"10.3390\/medicina62091704","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T08:07:06Z","timestamp":1788768426000},"page":"1704","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cervical Cerclage Performed at 24\u201332+0 Weeks in Twin Pregnancies: A Multicenter Descriptive Cohort Study"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9011-898X","authenticated-orcid":false,"given":"Yuki","family":"Gen","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Suwon 16247, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oyoung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Yeouido St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea,  Seoul 07345, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inhye","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Yeouido St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea,  Seoul 07345, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5618-9338","authenticated-orcid":false,"given":"Yun Sung","family":"Jo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Suwon 16247, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiyun","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Suwon 16247, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiyoon","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Suwon 16247, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8405-5170","authenticated-orcid":false,"given":"Kyung","family":"Yoo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, 222 Banpo-daero, Seocho-gu, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In Yang","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, 222 Banpo-daero, Seocho-gu, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6310-6206","authenticated-orcid":false,"given":"Hyun Sun","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, 222 Banpo-daero, Seocho-gu, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1027-7981","authenticated-orcid":false,"given":"Subeen","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, 222 Banpo-daero, Seocho-gu, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1016\/j.ajog.2010.04.031","article-title":"Twins: Prevalence, problems, and preterm births","volume":"203","author":"Chauhan","year":"2010","journal-title":"Am.
