Clinical studyRadiologically Placed Tunneled Hemodialysis Catheters: A Single Pediatric Institutional Experience of 120 Patients
Section snippets
Materials and Methods
The study was approved by the institutional review board. A retrospective review of the interventional radiology database was performed to identify all patients who received radiologically placed tunneled hemodialysis catheters from April 1997 to July 2010. The medical records of these patients were reviewed for demographic, clinical, and periprocedural data. There were a total of 120 children in the study (61 female, 59 male), with mean and median patient ages of 13.3 years and 15 years,
Results
A total of 523 procedures were performed in 120 patients during the study period. There were 193 primary catheter insertions, with 84 patients (70%) having only one catheter insertion and 36 patients (30%) having two or more primary catheter insertions. The latter group of patients had repeat insertions, ranging from two to six insertions each, for a total of 58 repeat insertions. The indications for repeat primary insertions included failed salvage for mechanical complications in 23 of 58
Discussion
Placement of hemodialysis and central venous catheters in pediatric subjects has been shown to be technically challenging and associated with higher rates of complications compared with their placement in the adult population (1, 24, 25). Higher success rates and lower complication rates have been reported for radiologically placed catheters in adult and pediatric populations (1, 3, 8, 9, 11, 12, 13, 14, 15). The 100% technical success rate reported in the present retrospective series further

Hemodialysis Catheters in Infants: A Retrospective Single-Center Cohort Study
2020, Journal of Vascular and Interventional RadiologyCitation Excerpt :Procedures requiring a return visit to IR (eg, catheter exchanges, contrast evaluations, cuff adjustments, resuturing) were called IR-maintenance procedures. Technical success, device service intervals, access site intervals, and complication categorization were defined using SIR guidelines (16–19). Catheter-related infections were analyzed if they met Society of International Radiology (SIR) definitions of catheter-related sepsis/bacteremia, with no alternative source of infection, and resulted in catheter removal (16).
Central venous catheter-related venous thrombosis in children with end-stage renal disease undergoing hemodialysis
2018, Thrombosis ResearchCitation Excerpt :Consequently, if a patient is severely oliguric or anuric at the time of dialysis, anticoagulation may no longer be required. CVC occlusion and thrombosis, not always amenable to local installation of fibrinolytic agents or systemic anticoagulation, may result in interruption of treatment, repeated CVC insertions (with potential acute insertion related complications [11,58,59,96]) and stenosis of the central vessels, potentially compromising future vascular access [53,73,74]. Central vein stenosis, affecting the major intrathoracic veins (subclavian vein, brachiocephalic vein, and SVC), is often asymptomatic, especially if the stenosis is not critical, or there is development of adequate collateral flow and is usually diagnosed at times of newly attempted CVC insertion or following the construction of an AVF in the ipsilateral extremity.
