Abstract：Objective: To investigate the value of three-dimensional ultrasound and three-dimensional color power Doppler ultrasound(3D-CPA) in cesarean scar pregnancy(CSP). Methods: One hundred and twenty-eight CSP patients were analyzed, the size of lesions, the thickness of the residual musclar thickness were observed by transvaginal three-dimensional ultrasound. 3D-CPA were used to get vascular index(VI), flow index(FI), blood vessels and blood flow index(VFI). According to the difference of clinical treatment, the patients were divided into two groups, one group was treated with dilatation and curettage without pretreatment, the other one was treated with pretreatment(UAE or MTX) and then with dilatation and curettage. The relationship between the above parameters and the amount of bleeding was observed. Results: The group which directly undergo dilatation and curettage: the size of lesions, VI and VFI have significant differences between the two groups(bleeding volume≥200 mL group or <200 mL group). After pretreatment, VI and VFI were significantly lower than that before pretreatment, the differences were statistically significant, and the hemorrhage risk of dilatation and curettage after the pretreatment was related to the lesion size, residual muscle thickness, VI and VFI. Conclusion: The application of three-dimensional ultrasound can show the relationship between the lesion and peripheral tissue clearly and comprehensively, 3D-CPA technology can quantitatively analyze the perfusion in lesion, which was significantly correlated with the amount of bleeding during operation.
