Abstract
Background:
Tunneled-cuffed catheter (TCC) reaching the mid-atrium has been demonstrated to be associated with improved catheter survival. However, whether similar conclusions can be made for femoral TCC reaching the inferior vena cava (IVC) remains unknown.
Methods:
Data from 47 patients with end-stage renal disease receiving right femoral TCC were retrospectively collected and analyzed. The primary patency, catheter dysfunction, and TCC-associated infection rate were compared between patients with TCC tip at the IVC and those with TCC tip at non-IVC.
Results:
TCC tips were located at the IVC in 26 patients and non-IVC in 21 patients. The technical success rates for both groups were 100%. The primary patency of the former group were significantly higher than those of the latter group at 3 months (92.3% vs 61.9%, p = 0.011), 6 months (80.8% vs 52.4%, p = 0.017), and 12 months (50.0% vs 28.5%, p = 0.024) follow-up, respectively. Kaplan-Meier curve analysis demonstrated significantly different catheter dysfunction-free survival between the two groups (log-rank p = 0.017). The overall TCC-associated infection rate was similar between the two groups (7.7% vs 9.5%, p = 0.82).
Conclusion:
Femoral TCC with tips at IVC was associated with higher primary patency, lower catheter dysfunction but similar TCC-associated infection rate as compared with those at non-IVC.
