A 32-year-old man with venous thrombus in the inferior vena cava for whom Gunther tulip vena cava filter was implanted. (a) Roentgenogram shows that a 4-French angled catheter that had been inserted into the retrieval catheter was introduced to enter into the cone from an interstice between the filter struts and to emerge from another space (arrows) and that a hydrophilic guide wire was inserted into the 4-French catheter. A snare wire was inserted through another 4-French angled catheter and captured the distal edge of the hydrophilic guide wire (arrowhead). Both the hydrophilic guide wire and the snare wire were pulled toward the cephalad site with tension maintained at both ends. (b) Roentgenogram shows that the hook of the filter that had migrated into the right atrium was captured by the retrieval set inserted from the left jugular vein (arrow). Note that a leg of the filter was snared tightly to avoid further migration (arrowhead)

A multi-snare (10 mm in diameter, pfm, Koln, Germany) was advanced into this 4-French catheter (Create Medics) and captured the distal edge of the hydrophilic guide wire that had been advanced from the 4-French angled catheter (Clinical Supply) through the inside of the GTF'S cone (Fig. 1a). Finally, another GTF retrieval set was inserted from the left jugular vein and the hook of the GTF was successfully grasped with the retrieval snare that was included in the GTF retrieval set (Fig. 1b).
