Abstract:
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.
