The Effect of Tip Placement on Fibrin Sheath Formation in Poorly Functioning Tunnelled Haemodialysis Lines
One of the most common causes of a poorly functioning haemodialysis (HD) line is the formation of a fibrin sheath. Tunnelled HD lines contain a Dacron® (Invista, Wichita, Kansas, USA) cuff at the skin entry site, which helps secure the catheter in place due to the fibrosis that occurs in the subdermal tissues.
