Aims and objectives
Percutaneous retrieval of foreign bodies is an increasingly utilized technique as the range of endovascular procedures continues to expand.
It is generally safe,
effective and avoids the morbidity associated with open surgical retrieval (1).
Myriad of endovascular devices have evolved including vascular access catheters,
guidewires,
endovascular stents and embolization coils (2).
Of notevena cava filter devices have assumed a clinically important role in the prevention of life-threatening pulmonary embolism (PE) when anticoagulation has been ineffective or contraindicated (1,2).However,
such devices when left in situ are...
Methods and materials
Study was approved from institutional review board.
In a 3 year period,
from April 2011 to February 2014,
6 consecutive patients underwent endovascular foreign body retrieval.
Data of all cases was retrospectively acquired using the radiology reporting database.
All six patients were males.
Age range was from 23 to 77 years (mean 48 years).
Indication for retrieval included 3 misplaced guide wires lost during central venous access procedures.
Others were 3 temporary OptEase inferior vena cava filters which were placed in patients with DVT secondary...
Results
Percutaneous retrieval of the intravascular foreign bodies was successful in all 6 patients (100%) in the first attempt.
Cases included 3 OptEase IVC filters and 3 misplaced guide wires introduced for central venous access.
Mean duration of IVC filter placement was 4 weeks.
Misplaced guide wires were recovered within 24 hours of recognition.
Additional devices for retrieval were not required in any case.
No major or minor procedure related complications were encountered.

Conclusion
Considering 100 % technical success,
we conclude that self made wire snares may be safely employed as effective endovascular retrieval devices,
particularly when availability of newer commercial devices and cost are a key concern.
