Methods: This multi-center retrospective study enrolled 781 women who delivered between May 1999 and February 2020. We divided the dataset into anterior (n = 209) and posterior (n = 572) groups and compared the baseline characteristics and obstetric and neonatal outcomes. The adverse obstetric outcomes associated with placenta location were evaluated using a multivariate logistic analysis. Results: Gestational age at delivery in the anterior group (253.0 \u00b1 21.6) was significantly lower than that in the posterior group (257.6 \u00b1 19.1) (p = 0.008). The anterior group showed significantly higher parity, rates of previous cesarean section, non-vertex fetal positions, admissions for bleeding, emergency cesarean sections, transfusions, estimated blood loss, and combined placenta accrete spectrum (p &lt; 0.05). In the multivariate analysis, the anterior group had higher rates of transfusion (OR 2.23; 95% CI 1.50\u20133.30), placenta accreta spectrum (OR 2.16; 95% CI 1.21\u20133.97), and non-vertex fetal positions (OR 2.47; 95% CI 1.09\u20135.88). Conclusions: These findings suggest that more caution is required in the treatment of patients with anterior placenta previa. Therefore, if placenta previa is diagnosed prenatally, it is important to determine the location of the body and prepare for massive bleeding in the anterior group.<\/jats:p>","DOI":"10.3390\/jcm13030675","type":"journal-article","created":{"date-parts":[[2024,1,24]],"date-time":"2024-01-24T09:57:42Z","timestamp":1706090262000},"page":"675","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Multicenter, Retrospective Comparison Study of Pregnancy Outcomes According to Placental Location in Placenta Previa"],"prefix":"10.3390","volume":"13","author":[{"given":"Seon Ui","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 16247, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Hye","family":"Jo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haein","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6352-2354","authenticated-orcid":false,"given":"Yoojin","family":"Na","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":"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, Seoul 06591, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"654","DOI":"10.1097\/AOG.0000000000001005","article-title":"Abnormal placentation: Placenta Previa, Vasa Previa, and Placenta Accreta","volume":"126","author":"Silver","year":"2015","journal-title":"Obstet.
