Salvage of Malfunctioning Peritoneal Dialysis Catheters: An Algorithm for Recanalization and Repositioning.

A peritoneal dialysis catheter salvage algorithm was developed and performed for 40 patients with documented catheter malfunction (obstruction and/or malposition) referred to the interventional radiology suite. This procedure utilized a metallic stiffener for repositioning and rotating dual guide wires for recanalization. A retrospective analysis of 35 cases of fluoroscopic manipulation showed that in 83% of the cases, the catheters were successfully repositioned and/or recanalized, and in 59%, they remained patent at 30 days. No major adverse events occurred. The results suggest that this algorithm is a safe and effective approach to salvage malfunctioning peritoneal dialysis catheters and that a trial of fluoroscopic salvage can be considered prior to surgical intervention.
