摘　　要：目的分析在剖宫产术后子宫瘢痕妊娠患者的诊断中通过应用经阴道超声的诊断价值。方法随机抽取2017年4月—2019年7月该院57例剖宫产术后子宫瘢痕妊娠患者为研究对象,分别进行经腹部超声检查与经阴道超声检查,统计诊断结果。结果经阴道超声在患者中的诊断准确率为96.49%,误诊率为3.51%,腹部超声的诊断准确率为85.96%,误诊率为14.04%,组间差异有统计学意义(P<0.05);经阴道超声在患者瘢痕肌层厚度、滋养层血流阻力指数中的测量结果均高于腹部超声,差异有统计学意义(t=4.529、5.182,P=0.013、0.004);腹部超声在孕囊类型的诊断准确率82.46%,经阴道超声为96.49%,差异有统计学意义(χ~2=5.961,P=0.015)。结论针对剖宫产术后子宫瘢痕妊娠患者行经阴道超声的诊断准确率显著高于经腹部超声,有利于降低误诊率并提升对患者瘢痕肌层厚度、妊娠囊位置、滋养层血流阻力指数等病灶征象的显示率。Objective To analyze the diagnostic value of intracavitary ultrasound in the diagnosis of uterine scar pregnancy after cesarean section.Methods From April 2017 to July 2019,57 patients with uterine scar pregnancy after cesarean section were randomly selected as the research objects,and transabdominal ultrasonography and transvaginal ultrasonography were performed respectively,and the diagnosis results were counted.Results The diagnostic accuracy rate of transvaginal ultrasound in patients was 96.49%,the misdiagnosis rate was 3.51%,the diagnostic accuracy rate of abdominal ultrasound was 85.96%,and the misdiagnosis rate was 14.04%.The difference between the groups was statistically significant(P<0.05);The measurement results of transvaginal ultrasound in the thickness of the scar muscle layer and the blood flow resistance index of the trophoblast were higher than those of abdominal ultrasound,and the difference was statistically significant(t=4.529,5.182,P=0.013,0.004);abdominal ultrasound in the gestational sac The diagnostic accuracy rate of the type was 82.46%,and the transvaginal ultrasound was 96.49%,the difference was statistically significant(χ2=5.961,P=0.015)Conclusion The diagnostic accuracy of transvaginal ultrasound is significantly higher than that of transabdominal ultrasound in patients with uterine scarring after cesarean section,which helps to reduce the rate of misdiagnosis and improve the rate of displaying lesion signs such as scar muscle thickness,gestational sac location,and trophoblastic blood flow resistance index.
