【摘 要】目的：研究经腹部及经阴道B超在剖宫产后瘢痕妊娠诊断中的临床价值。方法：选取2016年8月至2018年8月接诊的40例剖宫产后瘢痕妊娠患者进行研究。所有患者均采用经腹部及经阴道B超进行检查，观察超声表现状况。结果：40例瘢痕妊娠患者表现为单纯妊娠囊型、不均质包块及部分宫腔型3种类型。阴道B超诊断符合率(92.50%)明显高于腹部B超(65.00%)，两种诊断方式比较有统计学意义(χ2=9.0383，P=0.0026)。误诊病例分析中，阴道B超检查显示，黄体破裂出血1例，炎性包块2例，误诊病例经病理检查显示为单纯妊娠囊型;腹部B超检查显示，黄体破裂出血4例，残角子宫妊娠3例，炎性包块7例。结论：经阴道B超在剖宫产后瘢痕妊娠诊断中的临床价值较高，诊断符合率明显高于腹部B超，值得广泛应用。
