Background:
Renal patients with a tunnelled haemodialysis line are at risk of fibrin 'sheath' formation which can lead to occlusion. Dysfunctional lines are best treated by catheter exchange with a new subcutaneous tunnel; however, there is a risk of scarring, venous stenosis, potential loss of valuable access as well as the risk of infection.
Method:
We report a retrospective review of our experience using tunnelled line intraluminal plasty (TuLIP) in 11 patients over 16 months with fibrin sheath formation on pre-existing tunnelled haemodialysis catheters.
Result:
All patients responded well to treatment with median line patency post TuLIP reaching 112 days.
Conclusion:
TuLIP may have a role in extending catheter lifespan and delaying more invasive intervention.

Null and Alternative Hypotheses
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...
