Insights
Percutaneous retrieval of intravascular foreign bodies in children is a safe and effective procedure. Interventional radiology successfully removed embolized fragments from venous access devices in most pediatric patients.
Area of Science:
- Interventional Radiology
- Pediatric Medicine
- Vascular Surgery
Background:
- Vascular line use in children has increased, raising risks of intravascular foreign bodies.
- Percutaneous retrieval by interventional radiology is an established method for foreign body removal.
Purpose of the Study:
- To detail a single center's experience with percutaneous intravascular foreign body removal in pediatric patients.
Main Methods:
- Retrospective review of 18 pediatric patients undergoing retrieval between 2000-2008.
- Analysis of demographic data, clinical information, access device details, embolization site, and retrieval technique.
Main Results:
- Successful retrieval in 17 of 19 (89.5%) pediatric cases.
- Single-loop snares were used in 94.7% of successful retrievals.
- One unsuccessful retrieval required surgical intervention; another was retained.
Conclusions:
- Percutaneous intravascular foreign body retrieval is safe and effective in pediatric patients.
- Interventional radiology successfully removes embolized fragments from venous access devices.
Background:
The use of vascular lines both venous and arterial in children has significantly increased in the last decade with the potential risk that an intravascular device may become an intravascular foreign body. Percutaneous retrieval by interventional radiology has become an accepted method of foreign body removal.
Objective:
The objective of this study is to describe a single center's experience of percutaneous intravascular foreign body removal in pediatric patients.
Materials And Methods:
Between January 2000 and December 2008, 18 patients underwent percutaneous intravascular foreign body retrieval as a complication of venous access devices. The mean catheter days were 181.2 catheter days (1 to 1,146 days). A retrospective review was performed and demographic data and clinical information were recorded, including type, duration, location of access device, embolization location and retrieval technique.
Results:
Eighteen of 19 (94.7%) retrievals were performed with single-loop snares and 1/19 (5.3%) was a triple-loop snare. Seventeen of 19 (89.5%) retrievals were successful. One unsuccessful retrieval was successfully removed by surgery, while the other was retained.
Conclusion:
Percutaneous intravascular foreign body retrieval by interventional radiologists is a safe and effective method of retrieving embolized fragments from venous access devices in pediatric patients.
