case_images: However, a computed tomography (CT) scan of the IVC showed that the retrieval hook of a previously placed IVC filter had been removed, though the filter's legs had not expanded (Figure 1).
case_images: (left: 12*80 mm balloon dilated; middle: IVC partly revascularized; right: IVC partly occluded again 3 months post-surgery).

case_images: However, only partial recanalization was achieved in the IVC and the right common iliac vein (Figure 2). As expected, the IVC remained filled with chronic thrombosis, but limb swelling had significantly improved. (Figure 2) If severe symptoms recur despite strict anticoagulation, stent deployment may be considered as an option (Figure 2).
