Background: The “optimal” positioning of a permanent dialysis catheter tip has been long debated, with multiple conflicting recommendations. As with any other dialysis access, hydraulic performance is of paramount importance for tunneled catheters. This depends mainly on the catheter tip position. Thus, an agreement on the optimal catheter tip position is of significant importance. Methods: A retrospective review was performed to identify all patients requiring permanent dialysis access catheters from 2010 to 2017 at our institution. Demographic data including age and gender were collected. Data regarding access site, catheter type used, and tip location were also collected. Results: A total of 665 permanent catheters were placed in 595 patients. Multiple types of catheters including staggered tip and split tip were used. The tip location included distal superior vena cava, sinoatrial junction, distal right atrium, and inferior vena cava. Conclusion: Our data suggest that, among multiple variables including patient size, catheter length, type of catheter, and operator technique, tip location is the most important factor affecting catheter functionality and postprocedure complications. A standardized approach regarding tip positioning should be adopted to improve the catheter performance and prevent future complications.
