Abstract Objective: To explore the significance of three-dimensional reconstructional DSA used for evaluating the severity of iliac vein compression. Methods: Anterograde venography of lower extremity screened 72 patients as iliac vein compression, who were accepted in the author’s hospital from June 2019 to August 2021.Having further received three-dimensional reconstructional DSA and two-dimensional DSA, they were divided into three subgroups based on the degree of iliac vein compression (<50%, 50%-70% and >70%). Then the effect was compared between the two kinds of angiography on the visualization of iliac vein compression. Results: The proportion of lateral branch development and iliac vein impression was both rising with the severity of iliac vein compression under three-dimensional reconstructional DSA. Logistic regression analysis of ordinal categorical variables showed the severity of iliac vein compression reflected by contralateral iliac vein development was 16.66 times higher than that without development (P=0.003) and reflected by external iliac vein development was 19.13 times higher than that without development (P<0.001). The patients’ iliac vein compression was more severe when associated with contralateral iliac vein and external iliac vein development. Conclusion: Threedimensional reconstructional DSA can better reflect the information of iliac vein compression, especially lateral branch development and iliac vein impression trace can effectively assess the severity of iliac vein compression,which is worthy of further clinical study.
