目的 对比经腹部超声(TAS)与经阴道超声检查(TVS)对宫角妊娠的诊断价值。方法 选取我院2015年1月-2016年 12月间就诊的60例疑为宫角妊娠患者作为研究对象，均进行TAS和TVS和手术检查，以手术检查结果作为“金标 准”，评估TAS和TVS对宫角妊娠的诊断准确性。结果 TVS总诊断准确率为81.67%(49/60)，宫角妊娠诊断准确率为 85.19%(46/54)；TAS总诊断准确率为63.33%(38/60)，其中宫角妊娠诊断准确率为64.91%(35/54)；TVS总诊断准确 率及对宫角妊娠诊断准确率均高于TAS(χ2 =5.058，P=0.0245；χ2 =5.975，P=0.015)。结论 TVS对宫角妊娠的诊断 准确率高于TAS，能更好地鉴别诊断不同疾病类型，具有较高的临床应用价值。

Objective To compare the diagnostic values of transabdominal ultrasound (TAS) and transvaginal ultrasonography (TVS) in cornual pregnancy. Methods 60 suspected cornual pregnancy patients treated in our hospital from January 2015 to December 2016 were selected as the research objects, and all these patients were given TAS, TVS and operative examinations. The results of operative examination were taken as the gold standard, and the diagnostic accuracy rates of TAS and TVS in detection of cornual pregnancy were evaluated. Results The total diagnostic accuracy rate of TVS was 81.67% (49/60), and the diagnostic accuracy rate of TVS in detection of cornual pregnancy was 85.19% (46/54), the total diagnostic accuracy rate of TAS was 63.33% (38/60), and the diagnostic accuracy rate of TAS in detection of cornual pregnancy was 64.91% (35/54), the total diagnostic accuracy rate and the diagnostic accuracy rate of cornual pregnancy of TVS were higher than those of TAS (χ2 =5.058, P=0.0245; χ2 =5.975, P=0.015). Conclusion Comapred with TAS, TVS which has higher diagnostic accuracy rate of cornual pregnancy, can better differentiate different disease types, thus, it has higher clinical value.
