Abstract: Objective To investigate the value of three-dimensional color power angio(3D-CPA)in the prenatal diagnosis of pernicious placenta previa (PPP ) with placenta increta.Methods The ultrasonographic findings of PPP with placenta increta diagnosed in our hospital by 2D-CDFI and 3D-CPA were reviewed and compared with pathologic histology examination.For each of the two imaging methods, sensitivity,specificity,positive predictive value and prenatal diagnose accordance rate were summarized. Results For 3D-CPA,sensitivity,specificity and positive predictive value were 91.1%,88.9% and 93.3%, respectively.The results of 3D-CPA were higher than those in 2D-CDFI (sensitivity 76.4%,specificity 66.7%,positive predictive value 81.5% ),and were statistically significant (P <0.05 ).The diagnose accordance rate of 3D-CPA was statistically higher than that of 2D-CDFI (90.4% vs 73.0%;P <0.05). Conclusions 3D-CPA can display abnormal vascular reconstruction between the placenta and uterine wall from various angles,and is more accurate than 2D-CDFI.3D-CPA plays an important role in the prenatal diagnosis of PPP with placenta increta.
