造影剂推注装置在子宫输卵管实时三维超声造影中的应用

Application of contrast agent injection device in real-time three-dimensional hysterosalpingo-contrast sonography

目的:探讨子宫输卵管实时三维超声造影检查过程中造影剂推注压力峰值与不同输卵管通畅程度的相关性。方法:选择在本院超声医学科行子宫输卵管实时三维超声造影(RT-3D-HyCoSy)的70例女性患者,通过造影剂推注装置,测量检查过程中的压力峰值,比较输卵管不同通畅程度的压力差异,同时绘制ROC曲线,确定压力峰值的最佳截断值。结果:依据不同的输卵管通畅程度将造影结果分成3组:双侧通畅组、一侧阳性组及双侧阳性组,3组的压力峰值分别为(34.69±9.30)、(52.71±18.55)、(73.88±11.01)kPa,各组间比较,差异均有统计学意义(P<0.05)。双侧通畅组和一侧阳性组压力峰值ROC曲线下面积(AUC)为0.785,峰值压力最佳截断值为51.90 kPa,一侧阳性组和双侧阳性组压力峰值ROC曲线下面积(AUC)为0.851,峰值压力最佳截断值为73.50 kPa。结论:RT-3D-HyCoSy中造影剂推注压力峰值可作为一种判断输卵管通畅程度的量化指标,压力峰值的大小与输卵管的通畅程度存在相关性。

Objective:To investigate the correlation between the peak pressure of contrast agent injection and tubal patency during real-time three-dimensional hysterosalpingo-contrast sonography.Methods:Seventy female patients who underwent real-time three-dimensional hysterosalpingo-contrast sonography of uterine and oviduct in the Department of Ultrasound Medicine in our hospital were selected to measure the peak pressure in the examination process through the pressure injection device of contrast agent,to compare the pressure differences of different obturability patency degree of oviduct,and to draw a ROC curve to determine the optimal cut-off value of the peak pressure.Results:According to the different patency degree of fallopian tubes,the contrast results were divided into three groups the bilateral tubes unobstructed group,the unilateral tube lesioned group and the bilateral tubes lesioned group.The peak pressures of the three groups were(34.69±9.30),(52.71±18.55)and(73.88±11.01)kPa,respectively.The area under the peak pressure ROC curve(AUC)of the unilateral tube lesioned group and bilateral tubes lesioned group was 0.785,the optimal cut-off value of the peak pressure was 51.90 kPa,the area under the peak pressure ROC curve(AUC)of the unilateral tube lesioned group and bilateral tubes lesioned group was 0.851,and the optimal cut-off value of the peak pressure was 73.50 kPa.Conclusion:The peak pressure of contrast agent injection in RT-3D-HyCoSy can be used as a quantitative index to deduce the patency degree of oviduct.There is a correlation between the peak pressure and the tubal patency.
