PurposeTo report the outcome of tunneled dialysis catheter insertion in 120 patients.Materials And MethodsA retrospective review of the interventional radiology database and electronic medical records of 120 patients who had tunneled dialysis catheters inserted from April 1997 to July 2010 was performed with institutional review board approval. There were 61 female patients and 59 male patients, with a mean age of 13.3 years (range, 0.2-28.5 y). A total of 193 primary insertions and 330 salvage procedures were performed.ResultsThe technical success rate for primary catheter insertions was 100%. Immediate complications included self-limiting tract bleeding and air embolism in two of 193 insertions each (1.03%). Mean indwell duration for primary insertions was 66 catheter-days (range, 1-765 d), compared with a total mean of 159.4 catheter-days (range, 1-1,034 d). Rates of infection and mechanical complications were 0.21 and 0.9 per 100 total catheter-days, respectively. Mechanical and infections complications were increased in children younger than 9 years of age and weighing less than 20 kg. The catheter removal rates for infection and mechanical complications were 0.084 and 0.081 per 100 catheter-days, respectively. Medical salvage procedures, ie, intracatheter thrombolytic agent use or antibiotic therapy (52.1%) and interventional radiologic catheter salvage procedures (47.1%), increased catheter survival by an average of 54.8 days (range, 0-959 d).ConclusionsRadiologic placement of tunneled hemodialysis catheters is a safe and technically successful procedure in pediatric patients. However, there is a high rate of infectious and mechanical complications, particularly in younger and smaller patients.Copyright © 2012 SIR. Published by Elsevier Inc. All rights reserved.
