A cadaver study evaluating intraluminal anomalies of the left common iliac vein.

Objective: Intraluminal anomalies within the left common iliac vein, characteristic of iliac vein compression syndrome, are thought to result from compression by and pulsation of the overlying right common iliac artery. This cadaver study was designed to expand on the existing literature by surveying and photographing these spurs in addition to exploring whether certain factors, inherent to the cadaver, are associated with spur presence.

Methods: Dissection to expose the aorta, inferior vena cava, and common iliac arteries and veins was performed in 51 cadavers.
