Case contributed by Abdallah Al Khateeb


Recurrent left sided lower limb deep venous thrombosis of undetermined cause.

Patient Data

Age: 40 years old
Gender: Female

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.

Case Discussion

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