BACKGROUND: In dialysis patients with exhausted usual central venous access sites, the translumbar hemodialysis catheter (TLC) provides a viable option for dialysis access. The technical success of catheter insertion, associated complications, and long-term patency of TLC were evaluated in this study.
MATERIAL AND METHODS: This retrospective study included 37 patients with occluded central thoracic veins in whom 39 TLC implantation procedures were performed and 196 patients with internal jugular vein hemodialysis catheters (JVC). TLC implantation was performed as a hybrid procedure with computed tomography (CT)-navigated translumbar inferior vena cava cannulation and subsequent fluoroscopy-guided hemodialysis catheter placement.
RESULTS: The rates of technical success of the implantations and minor periprocedural complications were 97.4% and 10.3% in the TLC group and 98.6% and 4.2% in the JVC group, respectively. The median follow-up in the TLC and JVC groups was 673 days and 310 days, respectively. The primary-assisted patency at the 1-year and 3-year follow-up was 88.7% and 72.0% in the TLC group and 81.6% and 67.0% in the JVC group, respectively, with no statistically significant difference between the 2 groups. The incidence rate of infection-related and patency-related complications calculated for 1000 catheter-days was 0.15 and 0.11 in the TLC group and 0.33 and 0.25 in the JVC group, respectively.
CONCLUSIONS: The CT-guided implantation of the TLC is a useful option to create dialysis access with a low complication rate and satisfactory long-term patency in patients without usual venous access.
