[Removal of metallic foreign body in the soft tissue under fluoroscopy: 10 years of experiences].
OBJECTIVE
To summarize our 10-year experience with percutaneous fluoroscopically guided removal (PFGR) of metallic foreign body (MFB) in the soft tissue.


METHODS
PFGR was performed in 65 patients for removing a total of 368 MFBs from the soft tissues. The MFBs ranged from 0.2 to 0.3 cm in length embedded in the soft tissue for 7 days to 8 years. For superficial MFBs, the MFBs were removed directly with curved forceps under real time fluoroscopy. For deep MFBs, trocar technique was applied using the instruments for percutaneous diskectomy, with the outer cannula inserted toward the foreign body under real-time fluoroscopy followed by MFB removal by grasping forceps.


RESULTS
A total of 346 MFBs were successfully removed without any serious complications (success rate 94.0%), including 154 removed directly and 192 MFBs with trocal technique. The time of the procedures and radiation exposure for MFB removal was 30 s to 20 min and 1-6 min, respectively.


CONCLUSIONS
PGFR of MFBs in the soft tissue under fluoroscope is safe and effective. Direct removal using curved forceps is suitable for MFBs in superficial soft tissues, while trocal techniques needs to be utilized for deep MFBs.
