目的探讨经阴道三维超声对早期诊断输卵管妊娠中的临床价值。方法49例输卵管妊娠患者分别用经阴道三维成像和二维超声成像检查,并将两种方法的结果进行比较,其中36例经手术证实,12例保守治疗成功。结果经阴道三维超声能更好显示病灶内部的细微结构,提高了输卵管妊娠的早期诊断率。结论经阴道三维超声对早期诊断输卵管妊娠具有重要价值。 Objective To investigate the clinical value of transvaginal three-dimensional ultrasound in the early diagnosis of tubal pregnancy. Methods 49 cases of tubal pregnancy were examined by transvaginal three-dimensional imaging and two-dimensional ultrasound imaging, and the results of two methods were compared, of which 36 cases were confirmed by surgery, 12 cases of conservative treatment success. Results Transvaginal three-dimensional ultrasound can better display the fine structure of the lesion and improve the early diagnosis of tubal pregnancy. Conclusion Transvaginal three-dimensional ultrasound is of great value in the early diagnosis of tubal pregnancy.
