输卵管超声造影中输管通畅度定量的初步研究

Quantitative study of patency of fallopian tube in hysterosalpingo-contrast sonography

目的探讨四维子宫输卵管超声造影中运用通液诊疗仪产生的压力曲线的上升斜率定量评估输卵管通畅度的可行性。方法收集不孕症患者205例,造影检查时固定通液诊疗仪的造影剂浓度、通液量及通液速度,依据造影剂推注过程产生的实时压力曲线计算得到该曲线的上升斜率。根据超声造影结果分为一侧通畅组、一侧通而不畅组及一侧不通组。进行二元Logistic回归分析中,探讨斜率与输卵管的通畅性的相关性。结果二元Logistic回归分析显示一侧通畅组、一侧通而不畅组均与一侧不通组间斜率与输卵管通畅性有很好的相关性(回归系数及常数均P<0.05),而一侧通畅组与一侧通而不畅组间斜率与输卵管通畅性无相关性(回归系数P>0.05,回归常数P=0.000)。结论四维输卵管超声造影中产生的压力曲线的斜率值可用于定量评估输卵管的通畅性,为客观评估输卵管通畅性提供的新的辅助指标。

Objective To evaluate the feasibility of quantitative evaluation of fallopian tubes patency bythe rising slope of pressure curve produced by bolus injection using a liquid diagnostic apparatus in the four-dimen-sional hysterosalpingo-contrast sonography. Methods A total of 205 patients with infertility were collected for four-dimensional hysterosalpingo-contrast sonography. In the examination,the contrast medium concentration,the liquidvolume of the liquid diagnostic apparatus and the speed of the liquid were stationary calculated. The rising slope ofthe curve was calculated according to the real-time pressure curve produced by the contrast agent injection process.According to the hysterosalpingo-contrast sonography examination′s results,patients were divided into one sidepatency group,one side partial obstruction group and one side obstruction group. The correlation between the slopeand the patency of the fallopian tube was analyzed by binary logistic regression. Results Binary logistic regressionshowed that the slope and fallopian tube patency had good correlation（all P〈0.05）between one side patencygroup and one side obstruction group,and also between one side partial obstruction group and one side obstructiongroup;but had no correlation between one side patency group and one side partial obstruction group（regressioncoefficient P〉0.05,regression constant P = 0.000）. Conclusion The slope of pressure curve produced by four-dimensional hysterosalpingo-contrast sonography can be used to assess the patency of fallopian tubes quantitatively.It is a new auxiliary index for evaluating the patency of fallopian tubes.
