目的研究子宫峡部剖宫产瘢痕妊娠的彩色多普勒超声诊断价值。方法采取回顾性研究方法,选取子宫峡部剖宫产瘢痕妊娠患者23例作为研究对象,均通过彩色多普勒超声诊断,分析所有患者的临床基本资料以及多普勒超声声像图特征。结果 23例子宫峡部剖宫产瘢痕妊娠患者中,有11例患者妊娠囊较小、停经时间较短,占47.83%;4例患者因为停经时间长且位于宫腔内,占17.39%;3例患者切口处妊娠流产,占13.04%;5例患者因为院外人工流产术后阴道流血增多,诊断为瘢痕妊娠,占21.74%;经超声明确诊断21例,超声诊断符合率为91.30%(21/23)。彩色多普勒超声诊断子宫峡部剖宫产瘢痕妊娠患者的敏感性为89.4%、特异性为87.2%、准确性为88.1%。结论彩色多普勒超声诊断子宫峡部剖宫产瘢痕妊娠的价值较高,具有较高的敏感性、特异性以及准确性。
Objective To study the diagnostic value of color Doppler ultrasound in cesarean scar pregnancy in isthmus. Methods A retrospective study was conducted to select 23 patients with cesarean scar pregnancy in the isthmus. The color Doppler ultrasound was used to analyze all patients’ clinical data and the features of Doppler ultrasonography. Results Of the 23 cases of cesarean section with cesarean scar pregnancy, 11 cases had less gestational sac and shorter menopause time, accounting for 47.83%. Four cases had a long period of menopause and were located in the uterine cavity, accounting for 17.39%. Three cases The incidence of pregnancy induced abortion in the incision was 13.04%. Five patients were diagnosed as scar pregnancy because of increased vaginal bleeding after abortion, accounting for 21.74%. 21 cases were confirmed by ultrasonography and the coincidence rate was 91.30% (21/23 ). Color Doppler ultrasound diagnosis of uterine isthmus cesarean scar pregnancy in patients with sensitivity was 89.4%, specificity was 87.2%, accuracy was 88.1%. Conclusion The value of color Doppler ultrasonography in the diagnosis of cesarean scar pregnancy is high, with high sensitivity, specificity and accuracy.
