摘　　要：目的探讨三维经阴道超声联合断层成像技术在宫内节育器位置异常中的诊断价值。方法选取我院113例宫内节育器位置异常患者为研究对象,分别行二维经阴道超声、三维经阴道超声、三维经阴道超声联合断层成像技术检查,并以腹腔镜或宫腔镜手术结果为金标准,比较三者诊断宫内节育器位置异常的准确率。结果113例宫内节育器位置异常患者中,二维经阴道超声诊断73例,诊断准确率为64.60%;三维经阴道超声诊断99例,诊断准确率为87.61%;三维经阴道超声联合断层成像技术诊断111例,诊断准确率为98.23%。三维经阴道超声联合断层成像技术诊断不同类型宫内节育器位置异常的准确率最高,其对宫内节育器下移、变形的诊断准确率明显高于单独二维经阴道超声和三维经阴道超声,差异均有统计学意义(均P<0.05)。结论三维经阴道超声联合断层成像技术可清晰完整地显示宫内节育器形态,提高宫内节育器位置异常的诊断准确率,值得临床推广应用。Objective To explore the diagnostic value of three-dimensional transvaginal ultrasound combined with tomography in abnormal position of intrauterine device.Methods One hundred and thirteen patients with abnormal position of intrauterine device were enrolled in this study. Two-dimensional transvaginal ultrasound,three-dimensional transvaginal ultrasound,three-dimensional transvaginal ultrasound combined with tomography were performed.Laparoscopic or hysteroscopic surgery results were used as the gold standard,the accurate rate of the three diagnostic methods for diagnosis of intrauterine device position abnormalities was compared.Results Among the 113 patients with a bnor malposition of intrauterine device,73 cases were diagnosed by two-dimensional transvaginal ultrasound,the diagnostic accuracy was 64.60%.99 cases were diagnosed by three-dimensional transvaginal ultrasound,the diagnostic accuracy was 87.61%. Three-dimensionaltransvaginal ultrasound combined with tomography was used to diagnose 111 cases,and the diagnostic accuracy was 98.23%. Three-dimensional transvaginal ultrasound combined with tomography was the most accurate method for diagnosing the abnormal position of different types of intrauterine devices,and the diagnostic accuracy for the intrauterine device distortion and malposition was higher than that of two-dimensional transvaginal ultrasound and three-dimensional transvaginal ultrasound alone. The difference were statistically significant(both P<0.05).Conclusion Three-dimensional transvaginal ultrasound combined with tomography can clearly and completely show the shape of the intrauterine devices,and which can improve the diagnostic accuracy for intrauterine device position abnormalities,and which is worthy of clinical application.
