An 80-year-old woman presented with left lower limb pain and swelling with tenderness over the great saphenous vein. Venography revealed thrombus in the lower leg vein and occlusion of the femoral vein. A temporary vein filter was placed below the renal vein and catheter intervention was performed. The wire was carefully advanced from the left femoral vein to the vena cava. Hard resistance was felt at the proximal iliac vein. After balloon dilation, intravascular ultrasonography showed a very flat lumen at the occlusion site. Stent implantation was performed followed by anticoagulation therapy. Venography at 3 months follow-up showed a widely opened iliac vein. Angiography showed the occlusion site was the crossing point of the right iliac artery and left iliac vein. Stenting for iliac compression syndrome is effective to maintain patency of the vein.
