摘　　要：目的:应用多层螺旋CT血管成像(CTA),探讨无下肢静脉疾病症状人群左髂总静脉受压的发生率及其临床意义。方法:对无下肢静脉疾病症状的130例患者行多层螺旋CT下腹部增强扫描,在右髂总动脉跨越左髂总静脉水平,采用多平面重建方法,显示并测量两侧髂总静脉正交断面上的短径及面积。所有数据经统计学处理。结果:在正交断面上,左髂总静脉短径受压率为33.97%±2.01%,面积受压率为9.98%±1.49%,短径受压率明显高于面积受压率(t=9.586,P=0.000)。对左髂总静脉面积受压率进行统计分析,平均受压程度为9.98%,左髂总静脉受压大于25%的患者占16.92%(n=22),左髂总静脉受压大于50%的患者占3.85%(n=5),其中4例为女性。结论:在无下肢静脉疾病症状患者中,左髂总静脉明显受压(受压率>50%)者较少。Objective：To study the incidence rate and clinical significance of left common iliac vein compression among asymtomatic patients by using CT angiography.Methods： one hundred and thirty cases without signs of lower extremity diseases were evaluated with multi-slice helical abdominal CT angiography.Using multiplanar reformation technique,the anteroposterior diameter and area of bilateral common iliac veins were mesured in orthogonal cross-sectional planes at the point where the right common iliac artery crossed. The data were examined using t test and F test. Results： In the orthogonal cross-sectional planes, the mean compression extent on anteroposterior diameter of left common iliac veins was 33.97 %± 2.01%, on area of left common iliac veins was 9198 %±1.49 %.The mean compression extent on anteroposterior diameter of left common iliac veins exceeded the extent on area obviously（t=-9.586,P=0. 000）. Statistically, the mean compression extent on area of left common iliac veins was 9.98 %. The extent of greater than 25 % of compression on left common iliac vein was found in 16.92 %（n=22） of the patients,and 3.85 %（n=5） oft he patients revealed the extent of compression of greater than 50 %, 4 of which were female. Conclusion： Based on the abdominal CT angiography, in asymptomatic individuals there were few patients revealing more than 50 % extent of left common iliac veins. Left common iliac vein compression has no statistically significant age and gender diffcrences.
