目的探讨3D阴道彩超对异位妊娠的临床价值。方法将324例异位妊娠的超声表现与手术病理结果对照分析，293例手术治疗、45例保守治疗。结果异位妊娠三维阴道彩超诊断符合率84.7%，漏诊及误诊率为1.2%，其中附件区探及包块，结合血尿HCG基本可确诊，而局限只见宫内孕囊结构未仔细探及附件区而漏诊异位妊娠。未结合血尿HCG而把输卵管积脓误诊为异位妊娠破裂声像。结论3D阴道彩超对异位妊娠有很高的诊断准确性，其操作简单、无创，值得推广。“,”Objective To explore the value of transvaginal color Doppler sonographer in diagnosing ectopic pregnancy.Methods 324 patients diagnosed by transvaginal color Doppler ultrasound and the results were analyzed. Results Ectopic pregnancy transvaginal three-dimensional color Doppler sonography in the diagnosis of coincidence rate of 84.7%, missed diagnosis and misdiagnosis rate was 1.2%, which annex area and mass, combined with urine HCG can be diagnosed, limits and saw the intrauterine gestational sac structure without careful exploration and adnexa and missed diagnosis of ectopic pregnancy. Not with hematuria HCG to fal opian tube rupture were misdiagnosed as ectopic pregnancy.Conclusion 3D transvaginal color Doppler ultrasound has a high diagnostic accuracy for ectopic pregnancy, its operation is simple and noninvasive, and it is worth to be popularized.
