However, because of filter caudal hook intimal migration into caval wall, it was difficult to retrieve the filter into the 10 Fr. vascular sheath (Figure 1).
Fluoroscopic image showing IVC filter hook intimal migration at the L1 level. The filter caudal hook was difficult to snare because it became embedded into the IVC wall.. IVC: inferior vena cava.

The biopsy forceps was used to reform the filter struts tenting, and the filter was removed through the same introducer 10 Fr. sheath by correcting the tilt of the caudal filter hook and snaring the hook (Figures 2 and 3).
The IVC filter could be removed by disposable biopsy forceps. Correction of the tenting struts using the biopsy forceps and snaring of the filter hook are shown on a cavogram.. IVC: inferior vena cava.

The biopsy forceps was used to reform the filter struts tenting, and the filter was removed through the same introducer 10 Fr. sheath by correcting the tilt of the caudal filter hook and snaring the hook (Figures 2 and 3).
The filter hook migrated into the caval wall in venography.

To separate the filter hook from the underlying caval wall, we utilized the disposal intestine biopsy forceps that corresponded to a 6 Fr. sheath (Figures 4 and 5).
The filter hook could be retouched by disposable biopsy forceps.

To separate the filter hook from the underlying caval wall, we utilized the disposal intestine biopsy forceps that corresponded to a 6 Fr. sheath (Figures 4 and 5).
Snaring of the filter hook and removal of the filter body into 10 Fr. sheath are shown.
