[Practical aspects in the percutaneous extraction of foreign bodies using a Goose-Neck Snare].
OBJECTIVE
To present our clinical experience in the extraction of different foreign bodies (from vascular or other sites) using a goose-neck snare in 13 patients, with emphasis on practical and technical aspects used during the procedures.


METHODS
A total of 13 foreign bodies, including 9 intravascular objects and 4 in other locations, were included. The intravascular foreign bodies were stents (n = 2), coils (n = 2), fragments of broken central venous catheters (n = 3), and fragments of broken balloon catheters (n = 2). The nonvascular foreign bodies were fragments of broken double-J catheters (n = 2), one double-J catheter located entirely within the calyces of the kidney, and a fragment of a broken metallic guide wire in an intrahepatic bile duct. Goose-Neck Snares of different diameters (depending on the location) were used to extract the foreign bodies. Forceps were used as an auxiliary device in one patient with a fragment of double-J catheter, and in another case with a catheter fragment in a pulmonary vein, a pigtail catheter was also used to move the fragment and facilitate its extraction with the Goose-Neck Snare.


RESULTS
All of the foreign bodies were successfully extracted except a transjugular intrahepatic portosystemic shunt that migrated to the right heart cavities and was correctly repositioned in the right brachiocephalic venous trunk. No complications of any kind were seen during the procedures.


CONCLUSIONS
The Goose-Neck Snare is very useful, safe, and versatile for the extraction of different types of foreign bodies in different territories. Especially in vascular territories, it is necessary to have ample knowledge about and experience in the different techniques used for catheterization.
