Background: Split/fracture and embolization of central venous/shunt catheters are rare but serious complications in children. Percutaneous retrieval of intravascular foreign bodies is an important minimal invasive treatment. This study is aimed to represent our largest pediatric sample experience till now of 17 years from a single institution. Another aim is to compare the results regarding the removal or leaving in place of embolized or ruptured intravascular or cardiac venous catheter parts in children. Patients and Methods: A total of 26 cases were included in this study. Any pediatric patient with normal coagulation parameters and a fractured catheter fragment was included in this study. Other intravascular foreign bodies related to interventional devices and/or pacemaker/implantable cardiac defibrillator leads were excluded from this study. Results: Twenty-six patients, of whom 25 had oncologic diseases and 1 had a ventriculoatrial shunt, were included. The median age was 83.5 months (between 20 mo and 18 y) at treatment. Superior vena cava (9 cases), followed by the right atrium (5 cases), were the most two common sites of embolization for cardiovascular foreign bodies. The success rate of percutaneous retrieval was 92.3% in all patients. There were neither complications nor deaths. The retrieval technique revealed a predisposition for extraction through the femoral vein (96.1%) and using snare techniques (100%). Additional catheters like pigtail, National Institutes of Health, or ablation catheters were used for stabilization in selective cases in which the permanent central venous fragments stuck to the vessels. A tractional maneuver and capturing the ruptured material in the middle were other trick points for successful retrieval. Patients were asymptomatic in 76.9% of cases (20/26). Conclusion: Percutaneous retrieval of cardiovascular foreign bodies is a reasonable, safe, and effective way in children when the catheter fragments are free and mobile. It should be considered the preferred treatment option instead of surgery. In patients where catheter fragments are stuck and are adherent to vessels, it could be left, and followed up by anticoagulation. Novel techniques accompanied by an experienced team could be helpful in difficult cases.
