摘要
目的 探讨三维超声成像技术在宫内节育器 (IUD)定型与定位诊断中的应用价值。方法 对 30例经阴道二维超声检查怀疑IUD异常的患者行三维超声成像检查 ,通过对子宫腔与IUD的三维超声图像重建 ,明确IUD的形状与位置。将三维超声成像诊断结果与宫腔镜、腹腔镜或剖腹诊治结果进行对照。结果 2 9例患者 (96 .7% )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 ;1例因绝经 9年、子宫内膜菲薄而未能获取满意声像图 ,仅显示IUD嵌顿而无法显示IUD片段与宫腔的关系。诊断IUD完整者 17例 (单金属圆环 10例 ,γ型IUD 3例 ,宫腔型IUD2例 ,T型IUD 2例 ) ,IUD断裂者 13例 ;IUD嵌顿 2 4例 ,γ型IUD转位 3例 ,宫腔型IUD转位 1例 ,正常位置T型IUD 2例。 2 8例IUD异常患者中 2 6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 三维超声成像技术对IUD的定型和定位诊断具有很高的价值 。
Objective To assess the value of three dimensional ultrasound (3DUS) imaging in detecting the type and location of intrauterine contraceptive device(IUD). Methods Three dimensional ultrasound imaging examination was conducted in 30 patients suspected with abnormality of IUD based on transvaginal two dimensional ultrasound imaging examination. Through reconstruction of transvaginal 3DUS images, the type and location of IUDs were detected, and the results of hysteroscopy, laparoscopy or laparotomy were compared with the result of 3DUS. Results Satisfactory 3DUS images were obtained in 29 cases (96.7%) in which the type and location of IUDs and the relationship between IUD and uterine cavity were distinctly shown; satisfying imaging was not obtained in one menopausal case because of thinning of endometrium, the imaging only showed incarceration of IUD and not the relation between IUD fragment and uterine cavity. It was found that 17 IUDs (10 of single metal cirque type, 3 of γ type, 2 of uterine cavity type, and 2 of T type) remained intact and 13 became fractured. Twenty four IUDs were incarcerated, four were rotated (3 of γ type and 1 of uterine cavity type), and 2 T type IUDs were normal. IUD was removed by hysteroscopy, laparoscopy, or laparotomy successfully at one go in 26 of the 28 cases with IUD abnormality. The findings of operation was consistent with the results of 3DUS. Conclusion 3DUS is of great value in diagnosing IUD type and location, and helps select therapeutic plan.
