彩色多普勒超声诊断剖宫产子宫瘢痕部位妊娠的价值

Diagnostic Value of Color Doppler Ultrasound For Pregnancy in a Previous Caesarean Section Scar

目的通过3年的临床病例分析探讨彩色多普勒超声诊断剖宫产子宫瘢痕部位妊娠的临床应用价值。方法对内蒙古医科大学附属医院2009年5月至2012年5月收治的31例剖宫产子宫瘢痕部位妊娠二维及彩色多普勒超声表现进行回顾性分析。结果 31例患者中,22例二维声像图示胎囊型,9例为混合包块型。28例经阴道彩色多普勒超声显示血流丰富,3例血流不明显。29例彩色多普勒超声明确诊断为剖宫产子宫瘢痕部位妊娠,2例误诊,超声诊断符合率为93.55%。结论超声检查尤其是经阴道彩色多普勒超声是剖宫产子宫瘢痕部位妊娠最佳检查方法之一。

Objective To evaluate value of color Dopplerln the diagnosis of the pregnancy in the scar of previousCaesarean section three years. Methods Two diemensional （2D）and color Doppler flow imaging（CDFI） ultra sonograms of the 31 patients with pregnancyin previous caesarean section scars（May 2009 to May 2012） were retrospectively analyzed. Results All cases were verified by clinical and pathologic results, including 22 with gastrula type and 9 with commix mass type. Rich blood supply was observed in 28 cases by transvaginal color Dopper ultrasound, and the blood signals were weak in 3 case. 29 cases were correctly diagnosed by ultra- sound and there was 2 misdiagnosis, with the correct diagnosis rate of 93.55 %. Conclusion Ultrasonography, especially transvaginal color Doppler ultrasound, is one of the best methods for the diagnosis of the pregnancy in the uterine scar of previous caesarean section.
