Incidence and clinical significance of iliac vein compression.

Objectives: To determine the frequency of left common iliac vein (CIV) compression by the right common iliac artery (CIA) based on CT scan images.

Methods: CT scan images were reviewed and the diameter of CIV was measured at the area of minimal diameter and compared to the distal adjacent segment and the contralateral CIV at the same level. Medical records were reviewed for symptoms, deep vein thrombosis (DVT) and risk factors that might be associated with DVT.

Stent fracture in the brachiocephalic trunk.

Stents are commonly used as a tool for revascularization of different vascular beds in the body. However, many pitfalls have been reported with their use, such as thrombosis, migration, restenosis or fractures. The latter have been strongly correlated to in-stent restenosis with long-term follow-up.
