Objective: Tunneled-cuffed catheters (TCCs) are frequently used for establishing hemodialysis access for maintenance hemodialysis in older patients with exhausted resources of peripheral vessels. Fibrin sheath formation around the catheter is one of the most common complications of long-term use of indwelling catheter, which may cause the malfunction of the catheter. In this study, we intend to compare the prognosis of two catheter replacement methods, in situ replacement and replacement through a fibrin sheath crevice, with both being assisted by balloon dilation, and to explore the optimal catheter replacement process.
Methods: A retrospective study was conducted with 52 patients who underwent a replacement of their TCCs. Among them, 27 cases had their TCC replaced by the modified method of replacement through a fibrin sheath crevice and were referred to as the sheath crevice group, while 25 cases underwent in situ catheter replacement and were referred to as the in situ group. The primary outcome indicators included maximum blood flow in hemodialysis catheter and the urea clearance rate calculated by Kt/V values at the 1, 3, and 6-month follow-ups. The secondary outcomes included dialyzer alarms being set off and catheter-related infections during follow-up.
Results: There was no significant difference between the general data of the two groups. There was no massive blood loss during the replacement procedure. Neither were there cardiac tamponade, catheter-associated infections, or other complications. Follow-ups were made 1, 3, and 6 months after the replacement procedure. The sheath crevice group had higher catheter blood flow and Kt/V values at the 6-month follow-up than the in situ group did ([241.85±9.62] mL/min vs. [234.40±11.21] mL/min, P=0.014 and 1.31±0.55 vs. 1.27±0.49, P=0.005, respectively). During the follow-up process, access alarms were reported in 5 patients (three in the in situ group and two in the sheath crevice group) during dialysis. No catheter-associated infection occurred in either group.
Conclusion: The catheter replacement method of balloon dilation-assisted catheter insertion through a fibrin sheath crevice is safe and effective, resulting in better long-term catheter blood flow compared with that of in situ catheter replacement.
