We compared delivery modes, maternal and neonatal complications in OA versus OP deliveries, and HC \u226590th centile versus HC &lt;90th centile in persistent OP position. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Persistent OP position combined with HC \u226590th centile was associated with higher rates of vacuum extraction and unplanned cesarean delivery than HC &lt;90th centile in OP position (20.1 vs. 17.2%, OR 1.53 [95% CI 0.99-2.36], and 23.4 vs. 9.2%, OR 3.326 [95% CI 2.17-5.11], respectively). Rates of prolonged second stage of labor and neonatal intensive care unit admission were also increased compared to those in either OA position with HC \u226590th centile or OP position with HC &lt;90th centile. &lt;b&gt;&lt;i&gt;Discussion:&lt;\/i&gt;&lt;\/b&gt; Large HC combined with OP position is associated with higher rates of operative delivery and prolonged second stage of labor compared to OP delivery with HC &lt;90th centile. HC might be included with other measures to assess women in labor, as it is associated with fetal outcomes in OP deliveries.<\/jats:p>","DOI":"10.1159\/000478010","type":"journal-article","created":{"date-parts":[[2017,7,20]],"date-time":"2017-07-20T21:02:28Z","timestamp":1500584548000},"page":"51-58","source":"Crossref","is-referenced-by-count":13,"title":["Higher Rates of Operative Delivery and Maternal and Neonatal Complications in Persistent Occiput Posterior Position with a Large Head Circumference: A Retrospective Cohort Study"],"prefix":"10.1159","volume":"44","author":[{"given":"Oren","family":"Yagel","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah M.","family":"Cohen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michal","family":"Lipschuetz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tali","family":"Bdolah-Abram","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hagai","family":"Amsalem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doron","family":"Kabiri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simcha","family":"Yagel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2017,7,21]]},"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/478010","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/478010","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:35:06Z","timestamp":1745426106000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000478010"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,7,21]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,7,24]]},"published-print":{"date-parts":[[2018,7,26]]}},"URL":"https:\/\/doi.org\/10.1159\/000478010","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,7,21]]}}}
