经阴道三维超声诊断宫内节育器变形及异位

目的 探讨经阴道三维超声成像技术在诊断宫内节育器(IUD)变形与异位中的应用价值.方法 对32例二维超声检查怀疑IUD异常的患者行经阴道三维超声成像检查,通过对子宫腔与IUD的三维超声图像分析,明确IUD的形状与位置.将三维超声成像诊断结果 与官腔镜、腹腔镜或剖腹探查术结果 进行对照.结果 31例患者(96.9%)获取满意的三维超声声像图,可清晰显示IUD的形状、位置及其与子宫腔的关系.29例行宫腔镜、腹腔镜或剖腹取器手术,均一次取器成功,术中所见与三维超声诊断结果 一致.结论 经阴道三维超声成像技术在诊断IUD变形和异位中具有很高的应用价值.

Diagnosis of distortion and malposition of the intrauterine contraceptive device using transvaginal three-dimensional ultrasonography

Objective To assess the value of transvaginal three-dimensional ultrasonography in diagnosis of distortion and malposition intrauterine contraceptive device(IUD).Methods Three-dimensional ultrasonography examinations were con- ducted in 32 patients suspected with IUD based on transvaginal two-dimensional ultrasonography scan.Through reconstruc- tion of transvaginal three-dimensional ultrasonography,the type and location of each IUD was detected,and the findings of hysteroscopy,laparoscopy or laparotomy was compared with the result of three-dimensional ultrasonography.Results Sat- isfactory three-dimensional ultrasonography images were obtained in 31 cases(96.9%)in which the type and location of IUD and the relationship between IUD and uterine cavity were distinctly shown.IUDs were removed by hysteroscopy,laparosco- py,or laparotomy successfully in 29 of the 31 cases with IUD.The findings of operation were consistent with the results of three-dimensional ultrasonography.Conclusion Transvaginal three-dimensional ultrasonography is of great value in diagno- sis the distortion and malposition of IUD.
