BACKGROUND AND OBJECTIVES: For patients who rely on a tunneled cuffed catheter, the internal jugular vein is the preferred site of insertion. A few studies have suggested that the posterior approach for central lines is equivalent or better in comparison to the conventional central approach. However, there have been fewer studies examining tunneled cuffed catheter insertion using the posterior approach. We have performed many posterior insertions of tunneled cuffed catheters in our practice, and because the technique has not yet been comprehensively studied for long-term use, we performed a retrospective study to evaluate the safety and efficacy of posterior approach for tunneled cuffed catheter in maintained hemodialysis patients.

METHODS: A retrospective review was conducted of 200 hemodialysis patients who were treated with tunneled cuffed catheters over a period of 3 years. There were 104 patients in the study group, as well as a 96-patient control group, who underwent catheter insertion by central approach. The clinical follow-up data were collected and analyzed.

RESULTS: All catheters were successfully placed. The mean primary patency days per catheter were 712 catheter days for the study group and 585 catheter days for the control group. The episode of catheter infection was similar in both groups (p = 0.874), but the case of total catheter dysfunction was significantly lower in the study group compared to the control group (p = 0.006). The cumulative patency of catheters was higher in the study group than that in the control group (p = 0.02), while patient survival was the same in the two groups (p = 0.325).

CONCLUSION: The posterior approach is safe, and similar infection rates were observed with lower dysfunction rates compared to tunneled catheter insertion by the conventional central approach.
