摘　　要：目的 分析彩色多普勒超声对宫外孕破裂的诊断效能。方法 以2021年6月-2023年6月永丰县第三人民医院接收的80例疑似宫外孕破裂患者为研究对象,实施彩色多普勒超声检查,分析彩色多普勒超声诊断宫外孕破裂的声像图特征,比较宫外孕破裂阳性者与阴性者的多普勒血流参数[阻力指数(RI)、搏动指数(PI)与收缩期峰值流速(PSV)],统计彩色多普勒超声对宫外孕破裂类型的检出效果,以手术病理结果为金标准,分析彩色多普勒超声对宫外孕破裂的诊断效能。结果 宫外孕破裂阳性者的声像图特征表现为宫内无妊娠囊,子宫大小及内膜厚度正常,侧面附件区可见类圆形或不规则形包块,其边缘不清晰,内部多为不均匀性低回声,混浊杂乱,部分患者可见胎芽、原始心管搏动及假性妊娠囊等表现,其子宫直肠窝、盆腔内可见液性暗区,血流信号形态以点状、条状等表现为主。宫外孕破裂阳性者RI、PI值大于阴性者,PSV值小于阴性者(P<0.05)。彩色多普勒超声对不同类型宫外孕破裂的总检出率达96.55%。经分析,彩色多普勒超声对宫外孕破裂的诊断准确性为90.00%,敏感度为91.38%,特异度为86.36%。结论 彩色多普勒超声在宫外孕破裂检测中具有确切作用,可提供丰富的声像图特征与血流参数,对不同类型病灶均具有较高的检出率,诊断效能理想。Objective To analyze the diagnostic efficacy of color Doppler ultrasound in ectopic pregnancy rupture.Methods From June 2021 to June 2023,80 patients with suspected ectopic pregnancy rupture received by the Yongfeng County Third People's Hospital were studied.Color Doppler ultrasonography was performed to analyze the sonographic features of color Doppler ultrasonography in the diagnosis of rupture of ectopic pregnancy.The Doppler blood flow parameters[resistance index(RI),pulsatility index(PI)and peak systolic velocity(PSV)]of patients with positive and negative rupture of ectopic pregnancy were compared.The detection effect of color Doppler ultrasonography on the type of rupture of ectopic pregnancy was statistically analyzed.The diagnostic efficacy of color Doppler ultrasonography on rupture of ectopic pregnancy was analyzed with surgical pathological results as the gold standard.Results The sonographic features of patients with positive rupture of ectopic pregnancy were as follows:no gestational sac in uterus,normal uterine size and endometrial thickness,round or irregular mass in the lateral adnexal area,unclear edge,uneven low echo and turbidity in the interior,fetal buds,primitive heart tube pulsation and pseudo gestational sac in some patients,liquid dark area in the uterine rectal fossa and pelvic cavity,and punctate and strip-like blood flow signals.The RI and PI values of patients with positive rupture of ectopic pregnancy were higher than those of patients with negative rupture of ectopic pregnancy,and the PSV value was lower than that of patients with negative rupture of ectopic pregnancy(P<0.05).The total detection rate of different types of ectopic pregnancy rupture by color Doppler ultrasound was 96.55%.After analysis,the diagnostic accuracy of color Doppler ultrasound for ectopic pregnancy rupture was 90.00%,the sensitivity was 91.38%,and the specificity was 86.36%.Conclusion Color Doppler ultrasound has a definite effect in the detection of ectopic pregnancy rupture,which can provide rich sonogra
