An intravascular foreign body is an iatrogenic complication that occur
s during arterial or venous catheterization or interventional procedur
es. The foreign body could either be a catheter fragment, a dislodged
coil, or a steel guide wire. From January 1987 to December 1992, 12 ca
ses of intravascular foreign-body removals were performed by a percuta
neous method at Mackay Memorial Hospital. Of the 12 cases, five were d
islodged steel guide wires, four were broken CVP catheters, two were d
islodged coils, and one was Port-A fragment. The techniques we used we
re the loop-snare technique (two cases) and stone basket retriever (10
cases). Eleven cases of intravascular foreign bodies were removed by
non-surgical percutaneous retrieval but one case was a failure due to
improper extraction of a dislodged steel guide wire. The patient recei
ved surgical extraction by regional venotomy finally. No major complic
ations were noted during or after these procedures.
