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 A total of 27 studies were selected comprising 74 children, plus our 14 unpublished cases.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.

Introduction: While a Desilets–Hoffman sheath rarely fractures, when it does, the presence of an intravenous foreign body can cause various complications. Case Presentation: A 74-year-old woman receiving hemodialysis for end-stage renal disease via a left forearm arteriovenous graft (AVG) was referred to the interventional radiology department following thrombotic occlusion of the AVG. A corrective procedure was initiated, and the 7F Desilets–Hoffman sheath fractured after the purse-string suture. A.035-inch guidewire was passed through the fractured sheath, and a 3.0-mm x 60-mm balloon catheter was inflated, allowing for the successful removal of the sheath fragment without complications. Conclusion: The fractured Desilets-Hoffman sheath was successfully removed in a patient with a loop arteriovenous graft using balloon-supported retrieval technique. [ABSTRACT FROM AUTHOR]

Several types of intravascular devices and catheters are frequently used for long-term drug therapy, especially for oncological patients. As a result, complications are becoming increasingly common, namely catheter embolization. Retrieving these devices is important, as embolized fragments may lead to serious consequences, such as arrhythmias, myocardial injury, thrombosis, infection, and even perforation and death. We describe 2 cases of long-term drug catheter (Port-A-Cath) fracture, incidentally documented in a routine chest radiograph. In both cases, percutaneous extraction was attempted, yet the procedure was complicated by embolization of smaller fragments into the arterial pulmonary vasculature. We describe unusual approaches in successfully retrieving the remaining fragments. The ideal approaches for removal of foreign bodies from the cardiovascular system differ from case to case, but percutaneous extraction should be preferred in most of the cases. Less common techniques may be helpful in challenging cases. [ABSTRACT FROM AUTHOR]

Peripheral catheter embolization to the heart is common but infrequently reported. In view of the hazardous complications of thrombosis, embolism, infection, arrhythmia and even death, percutaneous retrieval of such foreign bodies is usually attempted. Previously reported percutaneous technique of retrieval mainly involved the snaring technique. Herein, we report a novel nonsurgical retrieval technique for successful removal of a 46 cm long embolized intracardiac peripherally inserted central catheter by utilizing a flexible biopsy forceps. To the best of our knowledge, the use of flexible biopsy forceps for retrieval has hitherto been unreported and this case report therefore adds to the repertoire of percutaneous retrieval techniques for safe and easy removal of embolized catheters to the heart.

Relatamos o caso de um paciente com cateter vascular de longa permanência embolizado para o ventrículo direito. Este caso ganha peculiaridade por estarem as duas extremidades do cateter indisponíveis para serem laçadas, dificultando a sua captura pelas técnicas convencionais. Descrevemos um novo método para resgatar o corpo estranho através de sua porção central, utilizando apenas um cateter com dois sistemas independentes de "laço" e de "gancho".We report on the case of a patient with a long term vascular catheter embolized into the right ventricle. This case had unique characteristics since both ends of the catheter were inaccessible for snare, which made it difficult to capture them using conventional techniques. We describe a new method to retrieve the foreign body through its mid-point portion, using a single catheter with two independent snare and hook systems.

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.

This paper reports our experience with endovascular techniques for the retrieval of lost or misplaced intravascular objects. Over 12 years, 78 patients were referred for interventional retrieval of intravascular foreign objects. In this retrospective study, radiological procedure records and patients’ medical records were reviewed to determine the exact removal procedure in every case, to report success rates, and to identify significant procedure-related complications. Written, informed consent was obtained from all patients prior to the intervention; this retrospective analysis was performed according to the guidelines of the Institutional Review Board. Thirty-six of seventy-eight foreign objects (46%) were located in the venous system, 27 of 78 (35%) in the right heart, and 15 of 78 (19%) in the pulmonary arteries. For foreign object removal, in 71 of 78 (91%) cases a snare loop was used, in 6 of 78 (8%) cases a sidewinder catheter combined with a snare loop was used, and in 1 case (1%) a sidewinder catheter alone was used for foreign object removal. In 68 of 78 (87%) cases, primary success was achieved. In 3 of 78 cases (4%), foreign objects were successfully mobilized to the femoral vessels and surgically removed. In 7 of 78 cases (9%), complete removal of the foreign object was not possible. In 5 of 78 cases (6%), minor complications occurred during the removal procedure. In conclusion, endovascular retrieval of lost or misplaced intravascular objects is highly effective, with relatively few minor complications. On the basis of our findings, these techniques should be considered as the therapy of choice. [ABSTRACT FROM AUTHOR]

Abstract: Objective: Port-A catheter fracture with embolization is a serious complication. The percutaneous retrieval of intravascular foreign bodies avoids the need for surgery in this high risk population. We report on 14 patients who underwent percutaneous retrieval of dislodged Port-A catheters by loop retriever. Materials and Methods: Fourteen patients who had undergone percutaneous foreign body retrieval between 2002 and 2007 were evaluated retrospectively. In all procedures, retrieval of foreign bodies was performed using a 6.3-F angled wire loop retriever. Results: The percutaneous retrieval procedure was successful in all 14 patients. Repositioning of the foreign body was done in seven cases using an RC1 catheter for the intracardiac Port-A catheter fragments. Additional surgery was not required. No further complications, such as damage to the vascular wall, were noted. Conclusion: With the increasing use of indwelling catheters and interventional devices, we are frequently confronted with the problem of dislodged catheters. The percutaneous approach should be considered as the first choice when trying to resolve the problem of an embolized catheter in the cardiovascular system.

Peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication, and few cases have been reported in children. We report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. Catheter fragments may cause complications such as cardiac perforation, arrhythmias, sepsis, and pulmonary embolism. A 12-year-old female received chemotherapy for acute lymphocytic leukemia through a central venous port implanted into her right subclavian area. The patient completed chemotherapy without complications 6 months ago. Venous port was accidentally fractured during its removal. Chest radiographs of the patient revealed intracardiac catheter fragment extending from the right subclavian to the right atrium (RA) and looping in the RA. The procedure was performed under ketamine and midazolam anesthesia and fluoroscopic guidance using a percutaneous femoral vein approach. A snare with triple loops (10 mm in diameter) was used to successfully retrieve the catheter fragments without any complication. Percutaneous transcatheter retrieval of catheter fragments is occasionally extremely useful and should be considered by interventional cardiologists for retrieving migrated catheters and can be chosen before resorting to surgery, which has potential risks related to thoracotomy, cardiopulmonary bypass, and general anesthesia.
