Prediction of placenta accreta spectrum in placenta previa surgery using systemic inflammatory markers
Methods: This retrospective case-control study encompassed patients diagnosed with placenta previa who underwent cesarean section procedures between 2010 and 2024. The case group (PAS+) comprised patients who underwent hysterectomy, segmental resection (with histopathologically confirmed PAS), or had in situ placenta. Conversely, the control group (PAS-) included other patients. The systemic immune-inflammatory index (SII), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR) were calculated from the most recent preoperative complete blood count. A comparative analysis of demographic data, clinical findings, and systemic inflammatory markers was conducted between the groups.
Results: A total of 487 patients were analyzed, with 146 (30%) classified as PAS (+) and 341 (70%) as PAS (-). The PAS (+) group exhibited significantly higher values in terms of age, gravidity, parity, and the number of prior cesarean sections (P=0.004, P<0.001, P=0.018, and P<0.001; respectively). However, no significant correlation was identified between the two groups concerning systemic inflammatory markers.
Conclusions: Systemic inflammatory markers do not appear to be reliable for predicting placental invasion in previa patients.
