Abstract 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.
