Abstract :Placenta accreta (PA) is a serious obstetric complication associated with maternal morbidity and mortality. While ultrasonography and MRI are effective in the third trimester, early diagnosis in the first two trimesters remains elusive. This study aims to explore the utility of biochemical markers in early PA detection, addressing a critical gap in current diagnostic approaches. A retrospective analysis was conducted on patients diagnosed with placenta previa between October 2021 and December 2022. Cases were divided into PA and non-PA groups based on histopathological examination. Demographic, obstetric characteristics and serum analytes were compared between the groups to identify potential biomarkers for early PA detection. Patients with PA exhibited higher gravida, parity, and abortion numbers. First-trimester free β-hCG levels and second-trimester E3 levels were significantly elevated in the PA group compared to non-accreta cases. No significant differences were observed in PAPP-A, AFP, and second-trimester hCG levels. Additionally, postoperative leukocyte count was lower, and intrapartum bleeding frequency was higher in the PA group. Multiparity and the number of previous cesarean sections emerged as significant risk factors for PA, consistent with previous literature. While previous studies reported associations between biochemical markers and PA, this study uniquely identified significant associations with free β-hCG and E3 levels. Further research is warranted to validate these findings and elucidate their clinical implications.
