经阴道彩色多普勒超声对未破裂型输卵管妊娠的诊断价值

目的探讨经阴道彩色多普勒超声(TV-CDFI)在未破裂型输卵管妊娠的诊断与鉴别诊断的价值。方法对75例临床确诊的未破裂型输卵管妊娠的二维声像图、血供分布及血流动力学参数进行回顾性分析。结果未破裂型输卵管妊娠的二维声像图可分为三型,以“输卵管环”为特征性表现(占76%),回声多数(82.5%)高于同侧卵巢实质回声,多数(78.9%)位于卵巢内侧。“输卵管环”型和非特异性包块型以星点形血供分布为主,RI值比较无统计学差异(P>0.05)。胎心胎囊型血供最丰富,流速曲线呈高速低阻型。结论TV-CDFI对未破裂型输卵管妊娠的早期诊断价值较高,是一种有效的方法。

The value of transvaginal color Dopplor flow imaging In the diagnosis of unruptured tubal pregnancy

Objective To discuss the value of transvaginal color Doppler power imaging(TV-CDFI)in the diagnosis and differential diagnosis of unbroken tubal pregnancy. Methods Two-dimensional sonogram, blood supply distribution and hemodynamics in 75 cases of clinically confirmed unruptured tubal pregnancy were analyzed retrospectively. Results The two-dimensional sonograms of unruptured tubal pregnancy could be divided into three types. The "tubal ring" was the specific appearance(76%). Most(82.5%) of their echogenicity were higher than the parenchyma in the ovary, and mostly located interior to the ovary(78.9%). The "tubal ring" type and the non-specificity mass type were mainly asteria blood supply distribution. There were no significant statistical differences of RI value (P>0.05). Fetal heart and gestational sac type had the most affluent blood supply with high velocity speed and low resistance. Conclusion Transvaginal color Dopplor flow imaging is an efficient and valuable method for the early diagnosis of unruptured tubal pregnancy.
