Article Abstract
Background: Percutaneous retrieval of intravascular foreign bodies has recently increased as a treatment option.
Purpose: To report our single-center experience of the percutaneous retrieval of 14 intravascular embolized catheter fragments in children and to conduct a literature review.
Material And Methods: MEDLINE 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 A total of 27 studies were selected comprising 74 children, plus our 14 unpublished cases.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.
Results: Port 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 min (range = 1.7-80 min) and median procedure length was 60 min (range = 35-208 min).
Conclusion: Percutaneous retrieval of intravascular foreign bodies is a feasible, safe, and efficient technique in children and should be considered the preferred treatment option.
Background: Obstructive complications in the Fontan circulation pose significant risks to affected patients. Traditional management strategies may be insufficient, necessitating innovative treatment approaches. This case report discusses the use of the FlowTriever Retrieval System for percutaneous aspiration thrombectomy in a patient with a history of Fontan procedure who developed conduit obstruction due to thrombus formation.
Background: Patent ductus arteriosus (PDA) is a congenital heart defect that requires closure to prevent complications like heart failure and pulmonary hypertension. Catheter-based closure using devices such as the Amplatzer duct occluder is the preferred method due to its minimally invasive nature. However, device embolization is a rare but recognized complication, particularly in small children or high-flow PDAs.
Background: Urocystolithiasis is a common problem in dogs; many canine uroliths are resistant to medical dissolution. Novel management options would expand, and in some cases improve, current urolith retrieval strategies.
Hypothesis/objectives: To describe a previously unreported technique by the Ellik bladder evacuator (EE) to assist in minimally invasive, cystoscopic retrieval of canine cystoliths.
Intrarenal foreign bodies are rare and could be iatrogenic through direct penetration, penetration through the gastrointestinal tract (GIT), or retrograde migration from the lower urinary tract. We present Intraoperatively incidental findings of an intrarenal foreign body during percutaneous nephrolithotomy (PCNL) with no previous urological intervention. However, there is a significant multiple percutaneous liver abscess drainage and endoscopic procedures.
