异位妊娠的声像图特征及误、漏诊分析

Analysis of Characteristics and Missed Diagnosis and Misdiagnosis of Ectopic Pregnancy Sonogram

目的分析异位妊娠的超声声像图特征及误、漏诊情况,以提高术前超声诊断符合率。方法对经病理检查已证实的300例异位妊娠患者的术前超声检查资料,进行回顾性分析。结果异位妊娠声像图随着时间及病情转归的不同,其主要表现分为未破裂型,流产型,破裂型,陈旧型。300例异位妊娠中,诊断符合人数为287例,符合率为95.7%,误诊人数为7例,误诊率约2.3%,漏诊6例,漏诊率为2.0%。300例异位妊娠患者中发生在输卵管妊娠的285例,约占95.1%(其中输卵管壶腹部211例,峡部71例,间质部3例),宫角妊娠6例(约2.0%),宫颈疤痕切口妊娠7例(约2.3%),继发腹腔妊娠1例(约0.3%),宫内宫外复合妊娠1例(约0.3%)。结论异位妊娠超声声像图表现具有一定的特征性,检查者应结合临床资料综合分析,以降低术前超声诊断漏诊、误诊率,提高超声诊断符合率。

Objective To Analysis of Character and missed diagnosis and misdiagnosis of Ectopic pregnancy sonogram for the improvement of the preoperative diagnostic rate of ultrasound.Methods The pathological examination 300 cases of ectopic pregnancy confirmed by operation and pathological results were analyzed retrospectively.Results Figure with the time course and the condition of the different imaging ectopic pregnancy,which mainly consists of unruptured,abortion type,fracture type,old.300 cases of ectopic pregnancy,diagnosis for the number of 287 cases,the coincidence rate was 95.7%,7 cases were misdiagnosed,the misdiagnosis rate of about 2.3%,missed diagnosis in 6 cases,the missed diagnosis rate was 2%.300 patients with ectopic pregnancy in tubal pregnancy（285 cases,accounting for about 95.1% of the ampulla of fallopian tube in 211 cases,71 cases of interstitial tubal isthmus,3 cases）,6 cases of cornual pregnancy（about 2%）,7 cases of cervical scar pregnancy incision（about 2.3%）,1 cases of secondary abdominal pregnancy（about 0.3%）,intrauterine heterotopic pregnancy 1 cases（about 0.3%）.Conclusion Have certain characteristics of ultrasonographic manifestations of ectopic pregnancy,examination should be combined with the comprehensive analysis of the clinical data,preoperative ultrasound diagnosis in order to reduce the misdiagnosis rate,missed diagnosis,improve the coincidence rate of ultrasound diagnosis.
