Tunneled dialysis catheters are widely used for long-term hemodialysis (HD) vascular access, but they are many complications that may require catheter replacement. There are standard steps for placing a tunneled dialysis catheter, one of which is the peel-away sheath, a key device that makes this design function safely. However, there are many conditions that make non-peel-away techniques necessary. We report two cases in which the peel-away sheath could not be advanced despite adequate dilation, due to perivenous fibrosis from a previous catheter.
In both patients, tunneled dialysis catheter placement was performed in the left internal jugular vein due to catheter-related bloodstream infection (CRBSI) resulting from a non-tunneled dialysis catheter in the right internal jugular vein and an AVF in the patient's left arm that was no longer usable. After successful subcutaneous tunneling and dilation of the tissue tract with sequential dilators, the peel-away sheath encountered significant resistance and could not be advanced into the vein despite repeated attempts, including re-dilation and the use of a dilator-sheath combination.
Secure wire access was maintained. The decision was made to attempt a catheter-over-wire rescue technique. The tunnel catheter was then carefully advanced over the guidewire through the subcutaneous tunnel and into the tissue tract with gentle rotational movements. The catheter was advanced to the desired depth, aspiration and flushing of both lumens were successful, confirmed by chest X-ray after the placement procedure. Following placement of the tunnel dialysis catheter, the patient immediately underwent regular HD without complications.
Emphasize that while peel-away sheaths are standard, the catheter-over-wire technique is a viable salvage option when performed carefully by an experienced operator, emphasizing the importance of maintaining safe wire access.
