摘　　要：目的通过直接法多层螺旋CT静脉成像(MSCTV)分析左侧髂总静脉(LCIV)管径与下肢深静脉血栓形成(DVT)的相关性。方法回顾性分析218例下肢DVT患者(DVT组)MSCTV图像及168例对照组患者增强CT图像,测量LCIV管径并评估其受压程度。结果DVT组LCIV管径明显减小,平均(5.150±2.352)mm,对照组LCIV管径平均(6.401±2.550)mm,差异有统计学意义(Z=-5.453,P<0.05);LCIV压缩程度DVT组61%(50%~95%),对照组39.6%(0%~73%),差异有统计学意义(Z=-10.555,P<0.05),DVT组与对照组各组间男性与女性LCIV管径差异有统计学意义(P<0.05),DVT组与对照组各组间男性与女性LCIV压缩程度差异无统计学意义(P>0.05);回归分析显示LCIV管径与下肢DVT呈正相关。结论下肢MSCTV通过显示LCIV受压情况并量化其受压程度,可准确诊断DVT。LCIV管径减小是下肢DVT的独立危险因素。Objective To analyze the correlation of the left common iliac vein(LCIV)diameter and the lower extremity deep venous thrombosis(DVT)by direct multi spiral computed tomography venography(MSCTV).Methods The MSCTV images of 218 patients with lower extremity DVT(DVT group)and the enhanced CT images of 168 patients in the control group were analyzed retrospectively.The diameter of the LCIV was measured and the compression degree was evaluated.Results In the DVT group,the diameter of the LCIV significantly reduced,with an average value of(5.150±2.352)mm.In the control group,the average diameter of the LCIV was(6.401±2.550)mm.The difference between the two groups was statistically significant(Z=-5.453,P<0.05).The degree of compression in the LCIV was 61%(50%-95%)in the DVT group and 39.6%(0%-73%)in the control group,showed a statistically significant difference(Z=-10.555,P<0.05).There were statistically significant differences in LCIV diameter between males and females within both DVT and control groups(P<0.05),and there were no statistically significant differences in LCIV compression degree between males and females within both DVT and control groups(P>0.05).Regression analysis showed a positive correlation between LCIV diameter and lower extremity DVT.Conclusion The lower extremity MSCTV enables accurate diagnosis of DVT by visualizing compression of the LCIV and quantifying its degree of compression.A reduced diameter of the LCIV is an independent risk factor for lower extremity DVT.
