- W4210348764 abstract "Background: Accurate diagnosis of morbidly adherentplacenta (MAP) and differentiation between its variantsaccreta, increta and percreta, allows preparation of life saving measures, and enables planning for alternative surgicalprocedures saving the future fertility according to the severity of the case.Objective: Evaluate the accuracy of 2D, color Doppler,3D and 3D power Doppler in the assessment of MorbidlyAdherent Placenta (MAP) and the introduction of designedultrasound-history based scoring system for prenatal diagnosis of (MAP), and differentiation between its variants inpatients with previous cesarean section (CS) scar/s in correlation with the intraoperative findings.Materials and Methods: Ninety five pregnant women withpersistent placenta previa (after 28 weeks' gestation) and pervious history of uterine CS scar/s with mean 2 (1-6) cesareandeliveries were enrolled into the study, with mean age 30.08± 7.01 years, gravidity 3.9 ± 1.1 and parity 2.4 ± 1.5. Allpatients were evaluated with 2D, then color Doppler, Finally3D and 3D power Doppler ,each US finding suggestive forMorbidly Adherent Placenta (MAP) take a score; the cumulative score compared with the intraoperative final diagnosis.The diagnostic accuracy was evaluated by receiver operatingcharacteristic (ROC) analysis.Results: 2D had sensitivity (87.4%), specificity (92%),PPV (97.6%) and NPV (65.7%) for diagnosis of MorbidlyAdherent Placenta (MAP), while color Doppler had sensitivity (94.7%), specificity (92%), PPV (97.8%) and NPV(82.1%) , 3D power Doppler had sensitivity (93.7%) ,specificity (100%), PPV (100%) and NPV (80.6%) , finally 3Dsection of the bladder interface had sensitivity (62.1%),specificity (100%), PPV (100%) and NPV (41%). The diagnostic accuracy of the scoring system by using degree ofagreement (ROC curve) was (0.049) for 3D power Doppler, (0.049) for 2D US and (0.053) for color Doppler indiagnosis of MAP. The area under the ROC curve was significantly equivalent to all tools of diagnosis (for 3D powerDoppler 1.000, 2D US 0.975, color Doppler 0.967 and foroverall scoring 0.979)." @default.
