Impact of insertion site on complications in central venous access devices.

PURPOSE: There is still debate over the safest route for the placement of long-term central venous access devices. The aim of this study was to review a large, single-institution experience to determine the impact of access location on peri-operative complications.

METHODS

The records of patients undergoing subcutaneous port (SQP) and tunneled catheter insertion over a seven-year period were reviewed. Vein cannulated (subclavian (SCV) versus internal jugular (IJ) vein), and 30-day complications were assessed. Surgical complications included pneumothorax, hemothorax, infections, arrhythmia or malpositioning requiring intervention.

RESULTS

A total of 1,309 patients were included (618 SQP, 691 tunneled catheters). The location for insertion was SCV (909, 69.4%) and IJ (400, 30.6%). There were 69 complications (5.2%) (41, 4.5% SCV, 28, 7.0% IJV) including: malpositioning/malfunctioning (SCV 13, 1.4% and IJV 14, 3.0%), pneumothorax (SCV 4, 0.4% and IJV 1, 0.3%), hemothorax (SCV 0 and IJV 1, 0.3%), arrhythmia (SCV 1, 0.1%, and IJV 0), and infection within 30 days of placement (SCV 20, 2.2% and IJ 11, 2.8%). The complication rates were not significantly different based on site (p = 0.080).

CONCLUSION

There was no significant difference in complication rates when using the subclavian versus the internal jugular vein as the site for long-term central venous access.

LEVEL OF EVIDENCE: III, retrospective comparative study.
