The uterocervical angle (UCA) remains a promising sPTB predictor. However, its clinical significance has yet to be described in patients treated with a pessary.<\/jats:p><jats:p>\n            Methods This study analyzed data of patients treated with a pessary because of cervical shortening in singleton pregnancies. The patients were divided into 2 groups according to transvaginal ultrasound findings: the funneling group (n = 68) and the no-funneling group (n = 42). Moreover, we analyzed patients within these prespecified groups according to the UCA &lt; 95\u00b0 and \u2265 95\u00b0.<\/jats:p><jats:p>\n            Results Delivery occurred significantly earlier in patients treated with a pessary and with a high UCA \u2265 95\u00b0(p = 0.006). The median gestational age at delivery in patients treated with a pessary and with no funneling and a UCA &lt; 95\u00b0 vs. \u2265 95\u00b0 were 39.00 and 36.14 weeks, respectively (p = 0.005). In cases with funneling and a UCA &lt; 95\u00b0 vs. \u2265 95\u00b0 the mean gestational age at delivery was 38.14 and 38.07 weeks respectively (p=1,00). There was a significant negative linear correlation between UCA and the gestational age at delivery in all patients (p = 0.04), which was even profound in the group without funneling (p = 0.0002). However, we found no significant correlation between cervical length and gestational age at delivery in all patients (p = 0.42) as well as in the group without funneling (p = 0.28).<\/jats:p><jats:p>\n            Conclusion In spite of pessary treatment, patients with UCA \u2265 95\u00b0 presented with a higher risk of sPTB compared to patients with UCA &lt; 95\u00b0. This suggests that the UCA seems to be a better predictor of sPTB than the cervical length in patients receiving pessary treatment.<\/jats:p>","DOI":"10.1055\/a-2091-7179","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T23:05:54Z","timestamp":1683846354000},"page":"190-198","source":"Crossref","is-referenced-by-count":0,"title":["Prediction of Preterm Birth with the Uterocervical Angle in Singleton Pregnancies Treated with a Cervical Pessary"],"prefix":"10.1055","volume":"45","author":[{"given":"Ioannis","family":"Kyvernitakis","sequence":"additional","affiliation":[{"name":"Asklepios Clinic Barmbek, Departament of Obstetrics and Prenatal Medicine, Asklepios Medical School, University of Semmelweis, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Friederike","family":"von Gehren","sequence":"additional","affiliation":[{"name":"Asklepios Clinic Barmbek, Departament of Obstetrics and Prenatal Medicine, Asklepios Medical School, University of Semmelweis, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcel","family":"Malan","sequence":"additional","affiliation":[{"name":"Asklepios Clinic Barmbek, Departament of Obstetrics and Prenatal Medicine, Asklepios Medical School, University of Semmelweis, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmet","family":"Baschat","sequence":"additional","affiliation":[{"name":"Gynecology & Obstetrics, Johns Hopkins University, Baltimore, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holger","family":"Maul","sequence":"additional","affiliation":[{"name":"Asklepios Clinic Barmbek, Departament of Obstetrics and Prenatal Medicine, Asklepios Medical School, University of Semmelweis, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1379-5335","authenticated-orcid":false,"given":"Maciej","family":"Osinski","sequence":"additional","affiliation":[{"name":"Asklepios Clinic Barmbek, Departament of Obstetrics and Prenatal Medicine, Asklepios Medical School, University of Semmelweis, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,12,8]]},"reference":[{"key":"ref1","first-page":"247","article-title":"recommended definitions, terminology and format for statistical tables related to the perinatal period and use of a new certificate for cause of perinatal deaths.
