Effects of Abnormal Placental Location and Placenta Accreta Spectrum Disorder on the Risk of Hypertensive Disorders of Pregnancy

Background: This study aimed to investigate the effects of abnormal placental location and placenta accreta spectrum (PAS) disorder on risk hypertensive disorders pregnancy (HDPs). Methods: retrospective included 985 patients with 2100 normal location. The incidence HDPs in those concurrent PAS was analyzed. factors affecting pregnancy-induced hypertension (PIH) were analyzed using logistic regression analyses. Results: (3.55%) significantly lower than (8.23%) (p < 0.001). previa subgroup (2.87%) low-lying (6.48%) = 0.017). By including confounding (maternal age, gestational gravidity, parity, disorders, diabetes mellitus), (OR (95% CI) 0.252 (0.149, 0.426), p 0.001) or PIH 0.294 (0.169, 0.511), negatively correlated Subgroup analysis revealed that (2.66%) non-PAS (5.22%). However, 0.551 (0.242, 1.254), 0.156) not an independent factor HDPs. Conclusions: Abnormal could decrease It protective HDPs, especially PIH, but not.
