经阴道超声诊断异位妊娠756例声像图分析

目的探讨经阴道超声对异位妊娠的诊断价值。方法回顾性分析756例经阴道超声检查为异位妊娠的超声图像,找出其内在的声像图特征,所有病例均经腹腔镜或剖腹手术及病理证实。结果756例患者经阴道超声检查,正确诊断异位妊娠748例,诊断符合率达98.94%,其中输卵管妊娠743例,占98.28%。756例异位妊娠声像图中表现为子宫增大或轻度增大538例（71.1%）,子宫大小正常218例（28.83%）。内膜厚度在5～10mm604例（79.89%）,内膜厚度在10mm以上152例（20.1%）。其中80例阴道超声图像为附件区有完整胎囊型包块,60例见到卵黄囊、胎芽及心管搏动,664例在附件区探测到混合性、低回声或强回声包块。结论经阴道超声诊断异位妊娠准确率高,可作为异位妊娠早期诊断的首选方法。

Sonogram Analysis of Transvaginal Ultrasound in 756 Cases of Ectopic Pregnancy

Objective To study the diagnostic value of transvaginal ultrasound （TVUS） in ectopic pregnancy. Methods Retrospective analysis of 756 patients with ectopic pregnancy was performed . The parameters being examined included the pathology and the characteristic of sonogram. Results 748 （98.94%） patients were positively diagnosed with ectopic pregnancy, in which 743 （98.28%） had oviduct pregnancy. 538 out of the total 756 （71.1%） sonograms showed uterine hypertrophy. 604 patients had an endometrial thickness of 5-10 mm,and 152 patients had an endometrial thickness of 〉10 mm. Intact embryo sack was found in 80 sonograms. 60 sonograms showed vitellicle, embryonic bud and pulsation of cardiac tube. 2 sonograms showed gestation sac and embryonic bud in cervix. 664 sonograms showed a mixed pattern of low and high-level echo mass in the area of uterine adnexa. Conclusion The accuracy of TVUS in diagnosing ectopic pregnancy is high. TVUS may be used in the early diagnosis of ectopic pregnancy.
