Methods: In this retrospective case-control study, 545 pregnant women were enrolled and divided into five groups: control (n = 251), PP (n = 246), PP with accreta (PPA, n = 18), PP with increta (PPI, n = 27), and PP with percreta (PPP, n = 33). Preoperative serum levels of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), delta neutrophil index (DNI), prothrombin time, fibrin degradation products (FDPs), D-dimer, and activated partial thromboplastin time (APTT) were analyzed. Results: The PPP group demonstrated significantly higher values of FDP, D-dimer, NLR, PLR, SII, SIRI, and DNI, and lower APTT values compared to the other groups (p &lt; 0.001). For predicting PAS, SIRI and DNI showed the highest diagnostic performance, each achieving 100% sensitivity and specificity, with optimal cut-off values of 2.01 and 2.45, respectively. For predicting intraoperative blood loss \u22651000 mL, PLR and SIRI exhibited the highest diagnostic accuracy, with optimal cut-off values of 122.5 (sensitivity 76.6%; specificity 72.6%) and 2.25 (sensitivity 73.4%; specificity 74.1%), respectively. Conclusions: FDP, D-dimer, NLR, PLR, SII, SIRI, and DNI may serve as valuable biomarkers for differentiating PP from PAS, thereby enhancing preoperative risk assessment and guiding surgical planning to improve maternal outcomes. Additionally, PT, D-dimer, FDP, NLR, and DNI were identified as significant independent predictors of intraoperative blood loss.<\/jats:p>","DOI":"10.3390\/jcm14113884","type":"journal-article","created":{"date-parts":[[2025,6,2]],"date-time":"2025-06-02T10:21:49Z","timestamp":1748859709000},"page":"3884","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Role of Inflammatory and Coagulation Biomarkers in Distinguishing Placenta Accreta from Placenta Previa and Associated Hemorrhage"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5211-9263","authenticated-orcid":false,"given":"G\u00fclay","family":"Balka\u015f","sequence":"first","affiliation":[{"name":"Department of Perinatology, University of Health Sciences, Etlik Z\u00fcbeyde Women\u2019 s Health Care Training and Research Hospital, 06010 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u015eevki","family":"\u00c7elen","sequence":"additional","affiliation":[{"name":"Department of Perinatology, University of Health Sciences, Etlik Z\u00fcbeyde Women\u2019 s Health Care Training and Research Hospital, 06010 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,31]]},"reference":[{"key":"ref_1","first-page":"101172","article-title":"Ultrasonographic cervical length assessment in pregnancies with placenta previa and risk of perinatal adverse outcomes: A systematic review and meta-analysis","volume":"6","author":"Hessami","year":"2024","journal-title":"Am.
