Diagrams show the steps of the technique in retrieval stent filter placement. (A) Membranous obstruction of the inferior vena cava (IVC) complicated with IVC thrombosis. (B) After the IVC membranes were ruptured, an angioplasty of the obstructive IVC was performed with a 10-mm balloon catheter. (C) A stent filter was deployed by the transjugular approach with the Z-stent positioned to the obstructive IVC. (D) A further dilation of the obstructive IVC was performed with a 30-mm balloon catheter. (E) Full expansion of the stent filter in IVC was shown with partial compression of the thrombosis, whereas thrombolysis was carried out with the use of urokinase at 60,000 U/hr for 10 hours per day with an intravenous drop through the dorsal venous of the foot for approximately 7∼14 days. (F) Retrieval of the stent filter was performed approximately 14 days after placement by the transjugular approach with an Amplatz gooseneck snare. (G) The IVC was patent with complete obliteration of the thrombosis after removal of the stent filter.

Patient 2: Budd Chiari syndrome complicated with inferior vena cava (IVC) thrombosis in a 40-year-old man. (A) Multiplanar reconstruction sagittal computed tomographic image through the IVC showed a low-density (17 mm × 132 mm) thrombus with an irregular border in the right posterior wall of the IVC. Note also the membranous obstruction of the IVC. (B) Inferior vena cavagram revealed complete membranous obstruction of the supra-hepatic portion of the IVC with reversed blood flow into the right hepatic vein. Note also an irregular filling defect in the distal part of the occluded IVC. (C) Inferior vena cavagram demonstrated the IVC was unobstructed with a huge filling defect after rupture of IVC membranes and deployment of a retrieval stent filter in the region of the occluded IVC. (D) Inferior vena cavagram demonstrated the patency of IVC with complete obliteration of the thrombosis before removal of the stent filter. (E) The stent filter was grasped by the Amplatz gooseneck snare and was being gently pulled out by the transjugular approach 24 days after placement. (F) Inferior vena cavagram showed complete normalization of the diameters and flow after removal of the stent filter. (G) Two-dimensional longitudinal sonogram confirmed the patency of IVC with smoothness of the wall and normalization of the diameters 4 months after removal of the stent filter.
