Percutaneous retrieval of intravascular foreign body in children: a case series and review.
Abstract
BACKGROUND\nPercutaneous retrieval of intravascular foreign bodies has recently increased as a treatment option.\n\n\nPURPOSE\nTo report our single-center experience of the percutaneous retrieval of 14 intravascular embolized catheter fragments in children and to conduct a literature review.\n\n\nMATERIAL AND METHODS\nMEDLINE databases were searched for case reports and series including children and iatrogenic catheter fragments or guidewires retrieved through percutaneous techniques. We also conducted a retrospective analysis of 14 cases from our institution over a 14-year period. A total of 27 studies were selected comprising 74 children, plus our 14 unpublished cases. Statistical analyses were performed using Microsoft Excel version 2016.\n\n\nRESULTS\nPort catheter fragments and peripherally inserted central catheters (PICCs) were the most embolized foreign bodies and the pulmonary artery was the most common site of embolization in 44.1% of cases. Analysis of the retrieval technique demonstrated a preference for extraction through the femoral vein (81.7%) and using snare techniques (93.5%). The success rate of percutaneous retrieval was 96.6% with only 1.1% of procedure-related complications. Patients were asymptomatic in 77.2% of cases, presented septic complications in 2.3%, and no deaths were reported. Median fluoroscopy time was 10\u2009min (range\u2009=\u20091.7-80\u2009min) and median procedure length was 60\u2009min (range\u2009=\u200935-208\u2009min).\n\n\nCONCLUSION\nPercutaneous retrieval of intravascular foreign bodies is a feasible, safe, and efficient technique in children and should be considered the preferred treatment option.
