经阴道超声诊断卵巢妊娠价值的初步探讨

目的评价经阴道超声对卵巢妊娠的诊断价值。方法回顾性分析21例卵巢妊娠的超声图像特征，并与手术及病理结果进行对照分析。结果所有病例经阴道超声检查均诊断为宫外孕，9例未破裂型卵巢妊娠中，经阴道超声检查进一步提示部位在卵巢者3例，在卵巢表面者3例，部位不清者1例，误诊为输卵管妊娠2例，定位符合率66．7％；12例破裂型卵巢妊娠中，经阴道超声检查均未进一步提示病灶部位。其声像图特征为：子宫正常或略大，宫腔内未见胚囊；卵巢内部或表面见完整的胚囊结构或不均质强回声；或附件区见杂乱不均质回声，其内可测及或未测及完整的胚囊结构，盆腹腔常见多量游离液体。结论经阴道超声对未破裂型卵巢妊娠的术前诊断有一定价值。

Value of transvaginal ultrasonography in diagnosis of ovarian pregnancy

Objective To evaluate the value of transvaginal ultrasonography in diagnosis of ovarian pregnancy. Methods Ultrasound features of 21 cases of ovarian pregnancy were retrospectively studied in comparison with those of surgery and pathology. Results All the cases were diagnosed extrauterine pregnancy and suggested 3 cases with the lesion localizing inside the ovary,3 cases superficial to the ovary, 1 case unclear localization and 2 cases misdiagnosed as tubal ectopic pregnancy, the correct localization was made in 66.7 % of 9 unruptured cases by endovaginal sonography. Twelve ruptured cases were unclear localization by endovaginal sonography. The sonographical appearance of ovarian pregnancies showed normal or little bigger uterus, empty uterine cavity, a gestational sac or inhomogenous strong echoes interior or superior to the ovary, or complex mass in the adnexal area with abundant free fluid in the pelvic. Conclusions Transvaginal sonography is of diagnostic value in ovarian unruptured pregnancy.
