Abstract
Objectives To evaluate ultrasound accuracy in diagnosing placenta accreta and its variants and to detect the potential value of uterine artery Doppler in diagnosing placenta accreta and to assess the impact of antenatal diagnosis in our population. Methods A total of 100 women with placenta previa were enrolled prospectively, all of those patients presented during the period of October 2017 to April 2018 to Kasr-Al Ainy Obstetrics casualty or outpatient clinic during their follow up visits in the 2nd and 3rd trimesters and underwent ultrasound examination by expert ultra-sonographer. An ult1rasound diagnosis (2D grayscale and color Doppler) of placenta accreta was based on the detection of the following: loss of the retroplacental clear zone, presence of abnormal placental lacunae, bladder wall interruption, placental bulge, myometrial thickness <1 mm, utero-vesical hypervascularity and bridging vessels, uterine artery Doppler was done for all cases enrolled in this study. Definitive diagnosis was made at delivery by Cesarean section. Maternal outcome in cases diagnosed antenatal was compared with that in cases diagnosed at delivery and the patient underwent CS hysterectomy, specimen was sent for histo-patholgical confirmation of the diagnosis of placenta accreta.Results A number of ultrasound criteria can be used in diagnosis of placenta accreta, as this study is showing their high accuracy, they include loss of retroplacental clear zone, presence of abnormal placental lacunae, myometrial thinning and utero-vesical hypervascularity, on the other hand both loss of retroplacental clear zone, abnormal placental lacunae can predict which patient will mostly have CS hysterectomy.No statistically significant value of uterine artery Doppler indices were observed during this study when placenta accreta cases were compared to placenta non accreta cases. Conclusion Our data confirmed that gray scale and color Doppler ultrasound have good performance in the diagnosis of AIP and that prenatal diagnosis improves maternal outcome
