“…The Palindrome catheter, with a symmetrical spiral end tip and laser-cut side slots, has the potential theoretical benefit of improved rheological performance, reduced propensity for thrombosis and CRBI, and hence enhanced catheter survival (6,(15)(16)(17). When compared with the Hemostar catheter, characterized by a staggered tip and machine-punched side holes, catheter survival was not different.…”

“…In this study, we find the coated catheter's mean indwell time to be 107 days. A recent paper by Spector et al 27 describing outcome with a similar design catheter without heparin coating showed that 13.9% of the catheters were removed due to clinical signs of infection compared with 10% (6 of 60) in this paper. The total infection rate with noncoated catheters was 1.4/1000 catheter‐days compared with 1.12/1000 catheter‐days in this paper.…”

In this paper we wish to report our clinical experience with a new heparin-coated dialysis catheter with a symmetric tip. Over a 16-month period, 60 heparin-coated Tal Palindrome catheters were placed in 57 patients. Catheter patency, catheter-related complications, and reasons for catheter removal were recorded. The patient's initial cause of end-stage renal disease, underlying diseases, and site of access were recorded as well. Patients were specifically followed for development of heparin-induced thrombocytopenia. Patient ages were 34-91 (average 66). Fifty-four percent of patients had a history of diabetes. Sixty catheters were placed for a total of 5353 catheter-days. The average catheter indwell time was 107 days (range of 2-381 days). Catheter-related infection occurred in 6 patients over the study period, with a rate of 1.12/1000 catheter-days. Bacteremia occurred in 3 patients with a rate of 0.56/1000 catheter-days. Six catheters were removed or exchanged due to malfunction. There was no incidence of heparin-induced thrombocytopenia. Initial clinical experience with the heparin-coated Tal Palindrome hemodialysis catheter demonstrated safe, reliable use, and low infection rates.

“…14 It is estimated that catheter dysfunction accounts for 17-33% of untimely catheter removals. 24,25 Therefore, the lower incidence rate of low blood flow observed with symmetricaltip versus step-tip catheters in this study may be a contributing factor to the significantly longer mean dwell time associated with this catheter design.…”

“…1,10 The symmetrical-tip dialysis catheter (Tal PalindromeÔ, Covidien, Mansfield, MA) is a recent catheter design with a symmetric, spiral tip, and biased ports. 14 Results from previous studies suggest that the symmetrical-tip catheter has several functional advantages over other catheter designs; for example, lower rates of thrombosis and re-intervention compared with split distal tip catheters, 15 and a lower dysfunction rate compared with steptip catheters. 16 However, there is relatively little clinical data describing long-term performance of the symmetrical-tip catheter for chronic hemodialysis, as much of the existing clinical research was conducted over a timescale of only a few months.…”

Hemodialysis catheters remain necessary for long-term vascular access in patients for whom arteriovenous access may be problematic or impossible. Developments in catheter design have improved long-term catheter functionality, and reduced the rate of infection and complications associated with their use. This retrospective study of 284 cases of chronic catheterization in 271 patients treated between 2009 and 2011 using Tal Palindromeä symmetrical-tip (N ¼ 118) or Quintonä Permcathä step-tip (N ¼ 166) hemodialysis catheters evaluates the efficacy and the safety of symmetrical-tip dialysis catheters for chronic hemodialysis, compared with a step-tip catheter. Measurements of catheter performance included mean catheter dwell time, incidence of low blood flow, and rates of infection and catheter-related blood stream infection (CRBSI). The symmetrical-tip catheter had a significantly longer mean dwell time compared with the step-tip catheter; 329.4 ± 38.1 versus 273.1 ± 25.4 d (p50.05). In addition, the rate of occurrence of low blood flow per 1000 catheter days was lower for the symmetrical-tip compared with the step-tip catheter; 1.13 versus 6.86 (p50.01). The symmetrical-tip catheter was also associated with a lower incidence of complications; the rates of infection (0.28 vs. 0.78; p50.01) and CRBSI (0.15 vs. 0.44; p50.01) were lower compared with those for step-tip catheters, and catheter removal occurred less often for the symmetrical-tip catheter (8% vs. 16%; p50.05). The symmetrical-tip hemodialysis catheter was associated with a longer mean dwell time, lower incidence of low blood flow, and lower infection rate compared with the step-tip catheter.
