经阴道超声与经腹部超声诊断异位妊娠的比较

目的比较经阴道超声(TVS)与经腹超声(TAS)在异位妊娠诊断中的价值。方法对109例异位妊娠患者以双盲法分别进行经腹部和经阴道超声检查。结果子宫清晰显示率、子宫内膜测定率、盆腔肿块显示率、盆腔肿块清晰显示率、肿块内检出孕囊样结构及原始心管搏动率,以及肿块内彩色血流信号检出率,TVS均明显高于TAS。结论TVS比TAS诊断异位妊娠更准确。临床诊断疑为异位妊娠的患者,应首选进行TAS或TVS检查,有条件的医院应常规进行TVS检查。

Comparison of transabdominal ultrasound and transvaginal ultrasound in diagnosis of ectopic pregnancy

Objective To compare the value of transvaginal sonography(TVS)and transabdominal sonography(TAS)in diagnosis of ectopic pregnancy.Methods One hundred and nine patients with ectopic pregnancy were examined by transabdominal ultrasound and transvaginal ultrasound with double blind method.Results The uterus clear display rate,the endometrium mensuration rate,the pelvic lump display rate,the gestational sac and heart tube of the lump display rate,and the color Doppler flow signal detection rate of TVS group were higher than that of TAS group.Conclusion TVS is more accurate than TAS in diagnosis of ectopic pregnancy.In clinic,patients with suspected ectopic pregnancy should be first examined by TAS or TVS,and TVS is better than TAS in diagnosis of ectopic pregnancy.
