目的探讨经阴道彩色多普勒超声检查在胎盘残留中的临床诊断价值。方法对2014-07/2015-12四川省人民医院经病理诊断结果为胎盘残留的56例患者的术前经阴道彩色多普勒超声图像特征进行研究。根据病理诊断结果将56例患者分为胎盘残留非植入组和植入组,分别为19例及37例。采用GE LOGIC E9彩色多普勒超声诊断仪经阴道检查,观察病灶部位、范围、与子宫肌层的关系等。将经阴道彩色多普勒超声检查指标与病理结果进行对照分析,评价此方法诊断胎盘残留是否伴有植入的敏感性、特异性及准确性。结果应用经阴道彩色多普勒超声观察宫腔内病灶,病灶与周围子宫肌层的分界是否清楚对鉴别诊断非植入组和植入组具有统计学意义(P<0.05)。经阴道彩色多普勒超声鉴别胎盘残留是否伴有植入的诊断敏感度、特异度和准确性分别为68.4%、86.5%和80.3%。结论经阴道彩色多普勒超声能清晰的显示宫腔内病灶及病灶内部的血管灌注,具有较高的临床应用价值。 Objective To investigate the value of transvaginal color Doppler ultrasonography in the diagnosis of placental residue. Methods The transvaginal color Doppler ultrasonographic features of 56 patients with pathological diagnosis of placental residue in Sichuan Provincial People’s Hospital from July 2014 to 2015 were analyzed. According to the results of pathological diagnosis, 56 patients were divided into non-implantation placenta group and implantation group, which were 19 cases and 37 cases. By GE LOGIC E9 color Doppler ultrasound diagnostic vaginal examination to observe the lesion site, scope, and the relationship between the myometrium and so on. Transvaginal color Doppler ultrasonography and pathological findings of the index control analysis to assess the diagnosis of this method of placental residue with the sensitivity, specificity and accuracy of implantation. Results The transvaginal color Doppler ultrasound was used to observe the intrauterine lesions and the clear boundary between the lesions and the surrounding myometrium. The difference between the two groups was statistically significant (P <0.05). The diagnostic sensitivity, specificity and accuracy of transvaginal color Doppler ultrasound in identifying whether placental residue is implanted are 68.4%, 86.5% and 80.3% respectively. Conclusion Transvaginal color Doppler ultrasound can clearly show intrauterine lesions and vascular perfusion within the lesion, which has a high clinical value.
