左髂总静脉受压程度稳定性在不同时间的CT增强图像上的对比

摘要

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.%目的:探讨同一患者左髂总静脉受压率在不同时间CT增强图像上的稳定情况.方法:共124例无下肢静脉疾病症状者进行了盆腔CT增强检查,并在1年内复查了CT增强检查,测量和比较2次检查中左髂总静脉受压率的变化程度,并分析年龄与左髂总静脉受压率的相关性.结果:同一患者的2次检查中,左髂总静脉受压率基本相同,两者差异无统计学意义(t=-0.957,P＞0.05).不同性别患者的左髂总静脉受压率在2次检查中均无明显变化(P＞0.05).无论受压率是否大于50％,左髂总静脉受压率在前后2次检查中的差异无统计学意义(P＞0.05).年龄和左髂静脉受压率无明显相关性(年龄＜50岁:r=0.152,P＞0.05;年龄≥50岁:r=-0.214,P＞0.05).结论:左髂总静脉受压程度基本稳定,不随检查时间变化,受压率与年龄无明显相关性,单次CT增强检查可以准确地显示、诊断左髂总静脉的受压程度.
