An ultrasound diagnosis (grayscale and color\/power Doppler) of placental attachment disorder (<jats:styled-content style=\"fixed-case\">PAD<\/jats:styled-content>) was based on the detection of at least two of the following (\u2018two\u2010criteria system\u2019): loss\/irregularity of the retroplacental clear zone, thinning\/interruption of the uterine serosa\u2013bladder wall interface, turbulent placental lacunae with high velocity flow, myometrial thickness\u2009&lt;\u20091\u2009mm, increased vascularity of the uterine serosa\u2013bladder wall interface, loss of vascular arch parallel to the basal plate and\/or irregular intraplacental vascularization.

The two\u2010criteria system identified 30 cases of placenta accreta, providing a sensitivity of 81.1% and specificity of 98.9%. When anterior and posterior placentae were considered separately, the detection rates of <jats:styled-content style=\"fixed-case\">PAD<\/jats:styled-content> were 89.7 and 50.0%, respectIvely.
