摘要
目的:3D髂静脉造影在慢性静脉功能不全型非血栓性髂静脉病变(NIVL)诊断中的应用价值。方法:回顾性分析我科2015年1月至2016年12月收治的NIVL患者的临床资料,比较3D和2D髂静脉DSA对NIVL的诊断差异及在造影剂量和曝光时间上的区别。结果:共选取175例患者,3D-DSA诊断NIVL的敏感性为91.1%,特异性为91.2%,Youden指数为0.823,阳性似然比分别为11.234,阴性似然比为0.097;Kappa值为0.825;McNemar检验提示P>0.05,诊断NIVL的AUC>0.9,3D造影时造影剂用量及造影曝光时间均更少(P<0.05)。结论:3D-DSA对慢性静脉功能不全型NIVL诊断的敏感性、特异性均较好,与2D-DSA有较好的一致性,且造影剂量与曝光时间较2D-DSA更具优势。
Objective:To investigate the value of 3D-iliac vein DSA in nonthrombotic iliac venous lesions(NIVL)with chronic venous insufficiency(CVI).Methods:Clinical data of patients with NIVL with CVI experienced both 3D and 2D-distal subtraction angiography(DSA)examination in our department from January 2015 to December 2016 were analyzed.The differences of two methods in the diagnosis of NIVL with CVI were compared.Results:Altogether 175 cases were collected.Compared with DSA in the diagnosis of NIVL with CVI,sensitivity,specificity,Youden index,positive likelihood ratio and negative likelihood ratio was 91.1%,91.2%,0.823,11.234 and 0.097 respectively.Kappa value was 0.825 and there was no significant difference(P>0.05,McNemar test)between the two groups.Both areas under curves(AUC)were>0.9,showed by receiver operating characteristic(ROC)curve;imaging contrast agents and imaging exposure time of 3D-DSA were less(P<0.05),with statistical difference.Conclusion:3D-DSA is remarkable in sensitivity and specificity for NIVL with CVI,which is consistent with 2D-DSA.There is no significant difference between 3D and 2D-DSA in the diagnosis of NIVL with CVI.3D and 2D-DSA is important in the diagnosis and preoperative assessment of NIVL with CVI,imaging contrast agents and imaging exposure time of 3D-DSA were less.
