Abstract
Purpose
To compare the clinical performance of a newly designed, symmetric-tip Arrow–Clark™ VectorFlow® tunnelled haemodialysis catheter, with a Glidepath™, symmetric-tip tunnelled haemodialysis catheter.
Material and Methods
From November 2018 to October 2020, patients with End-Stage Renal Disease requiring a de novo tunnelled catheter for hemodialysis, were randomized to Vectorflow® (n = 50) or to Glidepath™ catheter (n = 48). The primary outcome was catheter patency at one year following catheter insertion. Catheter failure was defined as the removal of the catheter due to infectious complications, or low blood flow rate by intraluminal thrombosis or fibrin sheath occlusion. Secondary outcomes were blood flow rate, fractional urea clearance and urea reduction ratio during dialysis.
Results
Demographic characteristics were not different between the two groups. At three months and on the one-year endpoint the patency rates with the Vectorflow® catheter were 95.83% and 83.33% respectively, compared to 93.02% at both endpoints with the Glidepath™ catheter (P = 0.27). Catheter failure to infectious complications or low blood flow rate was similar in both groups. Catheter blood flow rate reached the threshold of 300 ml/min at all time points for both catheters. All patients had a high mean fractional urea clearance (1.6–1.7).
Conclusions
The catheter patency rate was not significantly different in patients with a VectorFlow® or a Glidepath™ catheter. Both catheters presented satisfactory dialysis adequacy over one year.
