三维超声成像检查对39例子宫角部和输卵管间质部妊娠的诊断价值

Value of transvaginal three dimensional ultrasonography in diagnosis of 39 cases of cornual and interstitial pregnancy

[背景]探讨经阴道三维超声成像检查在诊断子宫角部和输卵管间质部妊娠中的价值.[病例报告]给39例疑有子宫角部和输卵管间质部妊娠患者进行阴道三维超声成像检查,并与手术病理检查结果及二维超声成像检查结果进行对比分析.39例患者中经三维超声成像检查诊断为子宫角部妊娠为21例,输卵管间质部妊娠为13例,正常妊娠为5例,对子宫角部妊娠的诊断结果与随访和病理检查结果比较准确率为100%,二维超声成像检查为77%,两者间差异具有统计学意义(P<0.05),对间质部妊娠诊断准确率亦有提高,但差异无统计学意义.[讨论]三维超声成像检查对子宫角部妊娠和间质部妊娠的特异性和敏感性均优于二维超声成像检查.

BACKGROUND To evaluate the value of transvaginal three dimensional ultrasonography in diagnosis of cornual and interstitial pregnancy.CASE REPORTS Transvaginal three dimensional ultrasonography was performed in 39 patients to diagnose cornual pregnancy or interstitial pregnancy.The results were compared with pathology and transvaginal two dimensional ultrasonography,21 cases were in cornual pregnancy,13 cases in interstitial pregnancy and 5 cases in normal pregnancy,and the diagnostic accuracy of transvaginal three dimensional ultrasonography and transvaginal two dimensional ultrasonography were 100% and 77%,respectively,and there had a significant difference in cornual pregnancy between two ultrasonography（P0.05）,and no statistical difference in interstitial pregnancy.DISCUSSION The diagnostic specificity and sensitivity for cornual pregnancy or interstitial pregnancy by transvaginal three dimensional ultrasonography are better than that by transvaginal two dimensional ultrasonography.
