To determine the accuracy of colour Doppler ultrasonography to diagnose placenta accreta. The authors reviewed cases of placenta accreta between January, 2008 and December, 2012. Ultrasonographic images consistent with signs ofplacenta accreta (numerous vascular lacunae, loss ofsubplacentalsonolucent space, absent lower uterine segment between bladder-placenta, turbulent or complicated blood flow at the uteroplacental interface) were correlated with findings at the time of surgery and pathologic examination. Over 60 months, 12 cases (0.48/1,000 deliveries) with suspected placenta accreta by ultrasonography were studied. The median gestational age atfirst diagnosis was 24 weeks. All cases had at least one previous cesarean delivery. At surgery, all cases had an adherent placenta requiring hysterectomy (five accreta, three increta, andfourpercreta). Four cases (33%) had accidental tear of urinary bladder Nine cases (75%) required blood transfusions. Colour Doppler ultrasonography appears useful in antenatal diagnosis ofplacenta accreta.
