Abstract:
Objective:To explore the compression stability in left common iliac vein (LCIV) at different times by contrast-enhanced CT in the same patients.Methods:This retrospective study included 124 patients (without signs of lower extremity venous diseases),who underwent contrast-enhanced CT at pelvic cavity and reexamined within one year.The degree of compression changes in LCIV was calculated and compared between the two examinations.Moreover,the relationship between age and the compression rate of LCIV was analyzed.Results:In the two examinations for the same patient,the compression rate of LCIV was almost the same,and there was no significant difference (t=-0.957,P＞0.05).Moreover,the compression rate of LCIV did not significantly change between different gender (P＞0.05).No matter whether the compression rate was more than 50％,there was no significant difference in the rate of LCIV compression between two examinations (P＞0.05).There was no significant correlation between age and the compression rate of LCIV (age＜50 years:r=0.152,P＞0.05;age ≥ 50 years:r=-0.214,P＞0.05).Conclusion:The compression degree of LCIV is almost stable,which is not significantly correlated with the age.The contrast-enhanced CT for single time can accurately display and diagnose the compression degree of LCIV.
