综合改良法下肢深静脉造影的临床应用

目的通过比较分析常规法与综合改良法在下肢深静脉造影中的显示率,分析常规法下肢深静脉造影时显影不良的原因,探讨综合改良法下肢深静脉造影的临床应用价值。方法回顾性分析了71例常规法下肢深静脉造影结果深静脉显影不良的原因。对47例患者采用了综合改良法下肢深静脉造影。对比分析常规法与综合改良法下肢深静脉造影的深静脉显示率。结果造影结果显示,常规单纯束扎法进行顺行造影中,深静脉显示率为60.76%;髂静脉图像优质率为37.97%;在综合改良法顺行造影中,深静脉显示率为86%,髂静脉图像优质率为64%;两种方法造影结果经统计学分析有显著性差异(p<0.05)。结论综合多种改良法行下肢顺行静脉造影,有助于下肢深静脉显示。

THE CLINICAL APPLICATION OF LOWERLIMBS VENOGRAPHY BY THE COMPREHENSIVE IMPROVEMENT METHOD

Objective To analyze the reasons for poor visualization of lower limbs venography using conventional method and probe into the clinical value of lower extremity venography using comprehensive method. Methods 71 cases had been reviewed to investigate the reasons of poor visualization of phlebography in deep vein. 47 cases accepted the composite ascending phlebography（APG） so as to compare and analyze the visualization of venography of lower limbs in the conventional method and comprehensive method. Results The phlebography showed that for the common APG and the improved APG,the visualization rates of deep vein were respectively 60. 76% and 86% and the high- quality image rate of iliac vein respectively accounted for 37. 97% and 64%. There was statistically significant difference between the groups（p 〈 0. 05）. Conclusion The comprehensive method may improve APG and contributes to the visualization of deep veins of lower limb.
