Abstract: Objective To evaluate multi-slice spiral CT venography (MSCTV) and digital subtraction venography (DSV) in diagnosing iliac vein compression syndrome (IVCS) and secondary thrombosis. Methods The imaging materials, including MSCTV and DSV performed before and after the thrombolysis therapy, of 38 patients with clinically-suspected IVCS were collected. The inner diameters of the compressed iliac veins were measured on MSCTV images and the compression ratio was calculated. Usingχ2 test, the detection rates of IVCS by MSCTV and DSV were compared. Results Of 38 patients, IVCS was detected by MSCTV in 29, by pretreatment DSV in 20 and by post-treatment DSV in 29. The difference in the detection rate of IVCS between MSCTV and pre-treatment DSV was statistically significant (χ2=4.65, 0.010.05). Conclusion For the diagnosis of IVCS, MSCTV is superior to pre-treatment DSV in the diagnostic accuracy of iliac vein compression syndrome. Therefore, MSCTV should be used as the preferred method of examination.(J Intervent Radiol, 2015, 24:301-305)
