The importance of imaging methods in catheter dysfunction: Two rare cases and their management

Cuffed-tunneled hemodialysis catheter is a reliable and effective alternative treatment option in the cases where all the peripheral vascular access points become useless for operative procedures or reinterventions. In addition, imaging methods have become more important to identify or prevent possible complications during or after catheter insertion. In this article, we report two rare cases to emphasize the importance of f luoroscopy and venography in determination and treatment of catheter-related complications and dysfunctions.
