Abstract:
Objective To explore the value of contrast-enhanced ultrasound(CEUS) in diagnosis of placental accrete,placental increta and placental percreta. Methods Twenty suspected patients of placental accrete, placental increta and placental percreta were examined with CEUS after routine ultrasound examination. Sono Vue was injected intravenously as bolus and a real time CEUS was performed to observe the characteristics. Results Comparison of 15 CEUS cases with uterine curettage, 8 cases had a clear relationship between the residual disease of the uterine cavity and uterine wall,7 cases had a thin thickness (2-4 mm) between the residual disease of the uterine cavity and uterine wall. Five of the 20 cases performed cesarean cesion,3 cases of the uterine serosa of placenta affixing part were very thin,incomplete and rough, demonstrating placenta increta and placenta percreta, 1 case of uterine rupture showed non-invasiveness between uterine wall and uterine serosa,and 1 case of placenta increta pathologically proven, initially suspected gestational trophoblastic disease by the CEUS. Conclusions CEUS provides an important diagnostic message for placental accrete, placental increta and placental percreta by showing the different characteristics of the perfusion image.
