经阴道三维超声在纵隔子宫诊断和鉴别诊断中的应用价值

目的：探讨经阴道三维超声在纵隔子宫诊断和鉴别诊断中的应用价值。方法：对55例疑似子宫畸形经阴道三维立体超声成像，与二维超声检查相比较，并和官腔镜、腹腔镜手术的结果做对照。结果：超声共诊断子宫畸形55例，经阴道二维超声符合率85．5％（47／55）；经阴道三维超声诊断符合率98．2％（54／55），三维超声对纵隔子宫的阳性预测值、阴性预测值均为100％。经阴道三维超声能更清晰显示子宫结构外形，特别是子宫腔及内膜的形态和结构。结论：经阴道三维超声对纵隔子宫诊断明显优于二维超声，与其他传统方法相比较，是一种无创、便捷、能更有效地诊断的子宫畸形，减少误诊的首选检查方法。

To Explore the Value of Transvaginal Three-dimensional Ultrasound in the Diagnosis and the Differential Diagnosis of Septate Uterus

Objective： To explore the value of transvaginal three-dimensional ultrasound in the diagnosis and the differential diagnosis of septate uterus. Method： 55 cases suspected of uterine malformations were respectively checked by transvaginal three-dimensional ultrasound and two dimensional ultrasound, then, the check-results of the three-dimensional or two-dimensional ultrasound were compared with final results from hysteroscopy and/or laparoscopy surgery. Result： The coincident rate of transvaginal two-dimensional ultrasound and hysteroscopy and/or laparoscopy was 85.4% （ 47/55 ） . Comparatively, the coincident of three dimensional was 98.2% （ 54/55 ）, and showed 100% positive and negative predictive value. Even more, the transvaginal three-dimensional ultrasound could show more details of the uterine, especially the shape and structure of the uterine cavity and endometrial. Conclusion： Transvaginal three-dimensional ultrasound diagnosis of septate uterus is significantly better than two-dimensional ultrasound, comparing with other traditional methods, it is the preferred method of examination, non-invasive, convenient and more effective in the diagnosis of uterine malformations and can reduce misdiagnosis.
