Inclusion criteria based upon clinical history and abdominal ultrasonography as follow: 1-Abnormal placental position,\nplacenta previa.\n2- Suspected placenta accreta (loss of the retroplacental sonolucent zone,\nirregular retroplacental sonolucent zone,\nthinning or disruption of hyperechoic serosa–bladder interface and presence of focal exophytic masses invading the urinary bladder.\nIn our study color doppler sonographic criteria for positive diagnosis of PA were diffuse or focal lacunar...\nResults\nThe age of our patients ranged from 23 to 40 years old with mean age 33.2 years.\nAll patientshad past history of uterine surgery,\n23/28 (82%) previous Cesarean section.\nAbnormal placental position was detected in all 100% patients (Low lie in 21/28 (75%),\npervia marginalis in 5/28(17.8%),\nand previa centralis in 2(7%) patients).\nAccording to the final surgical and pathological reports,\ncolor doppler sonography had sensitivity 90% to predict placenta accreta,\nspecificity 70%,\npositive predictive value 67%,\nnegative predictive value 92%,\naccuracy percentage 78%,\nand...\nConclusion\nColor doppler and MRI findings in patients with risk factors for placenta accreta were useful in establishing and prediction of antenatal placenta accreta diagnosis or exclusion with positive impact on the peripartum clinical management and clinical outcome of the affected patients.\nSonography and MRI have nearly the same sensitivity for prenatal diagnosis of placenta accreta.\nReferences\nUsta IM,\nHobeika EM,\nMusa AA,\nGabriel GE,Nassar AH.\nPlacenta previa-accreta: risk factors and complications.\nAm J Obstet Gynecol 2005;193:1045–1049.\nMazouni C,\nGorincour G,\nJuhan V,\nBretelle F.Placenta accreta: a review of current advances in prenatal diagnosis.\nPlacenta2007;28(7):599–603.\nTo WW,\nLeung WCPlacenta previa and previous cesarean section.\nInt J Gynaecol Obstet1995;51(1):25–31.\nRM Silver,LandonMB,\nRouse DJ.\nMaternal morbidity associated with multiple repeat cesarean deliveries.\nObstet Gynecol 2006;107:1226–1232.\nMoodley J,\nNgambuNF,\nCorr P.Imaging techniques to identify morbidly adherent placenta praevia: a prospective study.\nJ Obstet Gynaecol2004;24(7):742–744.\nYangJI,LimYK,...\nPersonal Information\nNadia El Ameen,\nMD.\nLecturer of Radiology.
