Abstract
PURPOSE: Patients undergoing long-term hemodialysis may suffer upper extremity central venous access failure and require an alternative route. This study aimed to evaluate the safety and efficacy of transrenal hemodialysis catheter insertion/replacement in patients with upper extremity central venous access failure. MATERIALS AND METHODS: A multicenter retrospective cohort study was made of transrenal hemodialysis catheter insertion/replacement performed between 2014 and 2020. The history of renal replacement therapy and central venous catheters and the technical details of transrenal hemodialysis catheter insertion/replacement, patency, removal and complications were obtained for all patients. RESULTS: Six insertion and four replacement procedures involving transrenal hemodialysis catheters were evaluated in six patients (M:F = 3:3; median age, 49.5 years). Percutaneous transrenal (right:left = 1:5) hemodialysis catheter insertion was technically successful without complication in all six patients. In two patients, the tract was not lost because the safety guidewire was still in place, so no second puncture was required. The mean procedure time was 33.0 ± 9.2 min. The mean primary patency duration was 107.3 ± 70.9 days. During the mean follow-up duration of 141.2 ± 137.1 days, four hemodialysis catheter replacement procedures were successfully performed for catheter malfunction (n = 2) and dislodgement (n = 2). Catheter removal was successfully performed in four patients after confirming normal coagulation, followed by subsequent renal replacement therapy. CONCLUSION: Percutaneous insertion/replacement of transrenal hemodialysis catheters is feasible, safe, and effective when upper extremity central venous access is exhausted, and the catheters can be maintained for a reasonable period of time. LEVEL OF EVIDENCE: Level 4, Case Series.
