The left common iliac vein is compressed against the vertebral body by the overlying right CIA.
The left common iliac vein is smaller than usual as it travels beyond the compression point due to chronic compression.

Appearances are consistent with May-Thurner syndrome and it explains the recurrent unilateral deep venous thrombosis in this patient.
