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.

“…Similar material has been described in banked blood components, hemodialysis tubing, hematopoietic stem cell collection lines, and in the LDL‐apheresis buffy coat, but this has not been described in TPE circuitry 1‐4 . The presence of PLTs and interspersed lymphocytes combined with the absence of fibrin suggest that the material's formation occurred secondary to the centrifugal layering of blood elements and procedural inefficiency.…”

“…Similar material has been described in banked blood components, hemodialysis tubing, hematopoietic stem cell collection lines, and in the LDL-apheresis buffy coat, but this has not been described in TPE circuitry. [1][2][3][4] The presence of PLTs and interspersed lymphocytes combined with the absence of fibrin suggest that the material's formation occurred secondary to the centrifugal layering of blood elements and procedural inefficiency. In banked components, similar material, referred to as "white particulate matter," is thought to result from centrifugal conditions and is composed of PLTs, white blood cells, fibrin, and cellular debris.…”

“…5 In dialysis, aggregates often occur in the "drip chamber," which is functionally analogous to the apheresis cassette reservoir, where an air/blood interface exists. 2 This phenomenon may be due to a combination of intraprocedural cellular loss compounded by intracircuit conditions. Fortunately, the material was not clinically problematic, as the 200-μm reservoir filter prevented it from entering the patient's circulation.…”

Dialysis catheters continue to play a vital role in the delivery of hemodialysis to patients for both temporary vascular access, serving as a bridge to permanent access, and for long-term access for patients with end-stage renal disease (ESRD). During the past decade, there has been an emergence of technological advancements in the design of dialysis catheters in an attempt to reduce catheter malfunction, decrease infection rates, and improve their long-term efficiency. New improvements in catheter design are aimed at translating into improved catheter performance. This review article summarizes some of the novel catheter designs developed within the last decade.
