经阴道彩超对输卵管间质部妊娠的诊断(附28例分析)
Journal of Practical Radiology(2008)
Abstract
目的探讨经阴道彩超(TVCDU)对输卵管间质部妊娠诊断的临床价值。方法对经手术和病理证实的28例输卵管间质部妊娠二维图像、血流分布情况及频谱特征进行回顾性分析。结果术前超声诊断为间质部妊娠17例,超声检出率为61%(17/28),其图像特征为子宫不对称性增大,一侧宫角部较对侧宫角膨隆,在膨隆处的宫角处探及妊娠囊或包块,包块与宫内膜不延续,包块围绕着肌层厚薄不一。超声图像可分为3种类型:孕囊型(7例)、不均质包块(16例)和破裂型(5例)。结论TVCDU对输卵管间质部妊娠的早期诊断与鉴别诊断具有重要的临床价值。
