Tunneled central venous catheters have two lumens, each having a length of 40 cm, 10 cm of which is tunneled under the skin; the cannulae are made of synthetic polymer with a large internal lumen and a Dacron cuff to ensure subcutaneous anchoring. The catheter characteristics rely on the type of polymer, design, and geometry Low-maintenance cost has been reported with the Groshong catheter (Bard Access, Cranston, RI, U.S.A.) relative to other tunneled right atrial catheters. 1, 5 The Groshong catheter has a slit valve at its tip and needs to be flushed only once a week with saline as opposed to daily flushes with heparinized saline for nonvalve tip catheters. Tunneled Catheters. Non-tunneled catheters are fixed in place at the site of insertion, with the catheter and attachments protruding directly. Commonly used non-tunneled catheters include Quinton catheters. Tunneled catheters are passed under the skin from the insertion site to a separate exit site, where the catheter and its attachments emerge Tunneled cuffed catheters, a type recommended by the NKF for temporary access, can be used for longer than 3 weeks when: An AV fistula or graft has been placed but is not yet ready for use.
Catheter-related thrombosis itself are of the most important complications of tunneled HD catheter, leading to access dysfunction, decreased quality of life and increased rate of mortality.

Depending on the expected use of the catheter, it may be tunneled or non-tunneled. Non-Tunneled Catheter Samples were not collected mainly when catheters were removed during the night shift or when samples thawed before/during transport. Table 1 gives the demographic details of the patient population. Two in each group received catheters for plasma exchange, the remaining patients for renal replacement therapy.
