The Diagnostic Value of Ultrasound Scoring Combined with Three-dimensional Power Doppler Blood Flow Perfusion Parameters for Placental Implantation Diseases
Objective To explore the application value of ultrasound scoring combined with three-dimensional power Doppler ultrasonography(3D-PDU)blood flow perfusion parameters in diagnosing different pathological subtypes of placenta accteta spectrum(PAS).Methods 112 pregnant women suspected of PAS were analyzed.Ultrasound scores were performed before surgery,and 3D-PDU examination was performed to measure vascularization index(VI),flow index(FI),and vascularization flow index(VFI).Using pathological diagnosis as the gold standard for grouping,the differences in blood flow perfusion parameters between each group were compared.Results Among the 112 suspected PAS cases,92 were confirmed by pathology.Compared with the non PAS group,there were significant differences in VI,FI and VFI(P all＜0.05).Among the 92 cases of PAS confirmed by pathology,24 cases did not invade the muscular layer,which was adhesive type,and 68 cases invaded the muscular layer,including implanted and penetrating types.The VI,FI and VFI of the invasive muscle group were higher than those of the non-invasive muscle group(P all＜0.05).When comparing the implanted type with the penetrating type,there was a significant difference in VI and VFI(P all＜0.05).The Kappa values for diagnosing adherent,implanted,and penetrating placental implantation using ultrasound scoring combined with 3D-PDU were 0.724,0.856 and 0.892,respectively.Conclusion The combination of ultrasound scoring method and 3D-PUD can quantitatively analyze the placental blood flow perfusion,and provide quantitative evaluation basis for the accurate classification of prenatal testing diagnosis of placental implantable diseases.
