Cases were defined as those with histological evidence of placenta accreta, and controls were defined as those without accreta. All subsequent pregnancies were evaluated to determine the recurrence risk of occult accreta in future pregnancies.<\/jats:p><jats:p>\n            Results\u2003Of 491 women with clinically adherent placentas, 100 (20.1%) with a pathological diagnosis of occult accreta were compared with 391 (79.9%) without occult accreta. In bivariable analysis, risk factors associated with occult accreta included a history of previous cesarean (19 vs. 10.7%; p\u2009=\u20090.03) and prior uterine surgery (35 vs. 19.7%; p\u2009=\u20090.001). Adverse obstetrical outcomes were more common in women with occult accreta including postpartum hemorrhage (59 vs. 31.7%; p\u2009&lt;\u20090.001) and peripartum hysterectomy (21 vs. 0.3%; p\u2009&lt;\u20090.001). In 130 subsequent pregnancies, there was an increased risk of retained placenta (42.9 vs. 19%; p\u2009=\u20090.04) and recurrence of occult accreta (29.6 vs. 6.8%; p\u2009=\u20090.05).<\/jats:p><jats:p>\n            Conclusion\u2003Occult accreta is associated with an increased risk of hemorrhagic morbidity and recurrence of morbidly adherent placenta in subsequent pregnancies.<\/jats:p>","DOI":"10.1055\/s-0038-1669440","type":"journal-article","created":{"date-parts":[[2018,9,5]],"date-time":"2018-09-05T19:00:31Z","timestamp":1536174031000},"page":"472-475","source":"Crossref","is-referenced-by-count":16,"title":["Occult Placenta Accreta: Risk Factors, Adverse Obstetrical Outcomes, and Recurrence in Subsequent Pregnancies"],"prefix":"10.1055","volume":"36","author":[{"given":"Clodagh","family":"Mullen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University Hospitals Case Medical Center, MacDonald Women's Hospital, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashley","family":"Battarbee","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of North Carolina School of Medicine, Chapel Hill, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda","family":"Ernst","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, NorthShore University HealthSystem, Evanston, Illinois"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan","family":"Peaceman","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Northwestern University Feinberg School of Medicine, Chicago, Illinois"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,9,5]]},"container-title":["American Journal of Perinatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1669440.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T18:44:36Z","timestamp":1554230676000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1669440"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,5]]},"references-count":0,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2019,4,2]]},"published-print":{"date-parts":[[2019,4]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1669440","relation":{},"ISSN":["0735-1631","1098-8785"],"issn-type":[{"value":"0735-1631","type":"print"},{"value":"1098-8785","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,9,5]]}}}
