Placenta Accreta Spectrum

Realistic reconstruction of angioarchitecture within the morphological landmark with three-dimensional sonoangiography (three-dimensional power Doppler; 3D PD) may augment standard prenatal ultrasound and Doppler assessments. This study aimed to (a) present a technical overview, (b) determine additional advantages, (c) identify current challenges, and (d) predict trajectories of 3D PD for prenatal assessments. PubMed and Scopus databases for the last decade were searched. Although 307 publications addressed our objectives, their heterogeneity was too broad for statistical analyses. Important findings are therefore presented in descriptive format and supplemented with the authors’ 3D PD images. Acquisition, analysis, and display techniques need to be personalized to improve the quality of flow-volume data. While 3D PD indices of the first-trimester placenta may improve the prediction of preeclampsia, research is needed to standardize the measurement protocol. In highly experienced hands, the unique 3D PD findings improve the diagnostic accuracy of placenta accreta spectrum. A lack of quality assurance is the central challenge to incorporating 3D PD in prenatal care. Machine learning may broaden clinical translations of prenatal 3D PD. Due to its operator dependency, 3D PD has low reproducibility. Until standardization and quality assurance protocols are established, its use as a stand-alone clinical or research tool cannot be recommended.

AbstractObjectiveTo select a group at high risk of placenta accreta spectrum disorders (PAS) based on the data of serum screening in the first trimester.MethodsA retrospective analysis of 48 patients with abnormal placental location (AP), including placenta previa (PP) only (n = 23) and PP and PAS (n = 25), was performed. Additionally, the AP group was divided depending on the blood loss volume: not higher than 1000 mL (LBL) (n = 29) and higher than 1000 mL (HBL) (n = 19); diagnostic term of PAS by ultrasound, data pregnancy-associated plasma protein-A (РAРР-A) and free β subunit of human chorionic gonadotropin (free β-hCG) multiple of median (MоM) at 11+0–13+6 weeks of gestation were evaluated. Serological markers were compared with the data of 39 healthy pregnant women with scar after previous cesarean section and normal placental location (control).ResultsThe mean gestation at diagnostic term of PAS was 29 weeks. PAPP-Р MоM [mean (M) ± standard deviation (SD)] was: in controls, 1.07 ± 0.47; in the AP group, 1.59 ± 0.24; in PP, 1.91 ± 1.52; in PAS, 1.30 ± 0.85; in LBL, 1.37 ± 1.20; in HBL, 1.91 ± 1.24. The difference between control/AP, control/PP, control/PAS, PP/PAS, control/LBL, control/HBL and LBL/HBL was Р = 0.256, 0.145, 0.640, 0.311, 0.954, 0.025 and 0.09, respectively. Free β-hCG MoM (M ± SD) was: in controls, 1.08 ± 0.69, in AP, 1.31 ± 0.96; in PP, 1.46 ± 0.19; in PAS, 1.16 ± 0.65; in LBL, 1.30 ± 0.06; in HBL, 1.32 ± 0.78. Comparison of free β-hCG AP with controls and between subgroups did not reveal a significant difference.ConclusionUnderestimation of PAS risk factors in pregnant women with AP leads to late diagnostics of pathology only in the third trimester. The assessment of the РAРР-A level in the first trimester may be helpful for the early prognosis of pathological blood loss at delivery for pregnant women with AP and for forming the high-risk group for PAS.
