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。
Objective To investigate the clinical value of transvaginal ultrasound (TVCDU) in the diagnosis of tubal pregnancy. Methods The 28 cases of tubal pregnancy confirmed by operation and pathology were retrospectively analyzed for two-dimensional images, distribution of blood flow and frequency spectrum. Results Preoperative ultrasound diagnosis of interstitial pregnancy in 17 cases, the ultrasound detection rate was 61% (17/28), the image features of the uterus increased asymmetry, the contralateral corner of the cornual Palace bulge, in the Bulging at the corner of the palace to explore and gestational sac or mass, mass and endometrial does not continue, mass around the muscular layer thickness varies. Ultrasound images can be divided into three types: gestational sac type (7 cases), heterogeneous mass (16 cases) and rupture type (5 cases). Conclusion TVCDU has important clinical value in the early diagnosis and differential diagnosis of tubal pregnancy.
