目的 探讨彩色多普勒超声在切口妊娠诊断和治疗中的应用价值。方法 回顾性分析40例切口妊娠患者的影像学和病史资料，分析子宫切口妊娠的声像图特征。结果 根据声像图病例分为孕囊型26例和不均质肿块型14例；根据症状病例分为无出血型10例，少量出血型17例，大量出血型5例,流产后出血型8例，发现不同症状类型的患者具有不同的超声图像特点，根据患者停经时间和孕囊体积采取不同的临床处理方案。39例患者在超声引导下行清宫术成功；1例患者因肿块较大，清宫术后又行全子宫切除术。结论 彩色多普勒超声可准确诊断切口妊娠，对临床治疗有重要的指导意义。

Objective To investigate the value of color Doppler ultrasound in the diagnosis and treatment of cesarean section scar pregnancy. Methods The imaging feature and clinical history of 40 patients with cesarean section scar pregnancy were retrospectively analyzed, and the ultrasound characteristics of cesarean section scar pregnancy were investigated. Results Gestational sac type and mixed mass type were divided based on the sonograms. Non-hemorrhage type, little hemorrhage type, massive hemorrhage type and post-abortion type were classified according to the symptoms. Different types had different ultrasonographic features, and were treated by different clinical treatment schemes. Conclusion Color Doppler ultrasound can accurately diagnose cesarean section scar pregnancy and may have significant value in guiding the treatment.
