超声诊断宫内节育器合并中、晚期妊娠的临床价值

摘要

目的:探讨应用超声诊断宫内节育器(IUD)合并妊娠的准确性及临床应用价值.方法:对16例带节育器合并妊娠的中、晚期妊娠患者行超声检查,直观地显示节育器在宫腔内的位置及类型.结果:本组带节育器妊娠均在妊娠中、晚期发现,多见于带节育器5年内.IUD下移是导致妊娠的最主要原因.结论:放置IUD后应用超声监护宫内节育器的位置是一种较为理想的监测手段,特别是放置IUD 5年内要加强随访,以便发现IUD下移,预防意外妊娠.%Objective: To evaluate the clinical application value and the veracity of ultrasonic diagnosis in the intrauterine device (IUD) with pregnancy. Methods: An ultrasonography was done for 16 patients during the second and third pregnancy with intrauterine device to directly show the type and location of the intrauterine device. Results: The ILJD of the 16 patients were all discovered during the second and third pregnancy, most of the patients applied the ILJD within 5 years. The moving down of the ILJD was the main reason of pregnancy. Conclusion: The ultrasound technique is suitable for women to monitor the position of ILJD, especially for those who has been with ILJD for less than 5 years. They should be strengthened follow-up in order to discover the moving down of the ILJD earlier and prevent unplanned pregnancy.
