fibrin sheath

Nursing A tubular scar that is a potential complication of long-term catheterization, in which the catheter becomes encased in a fibrotic sheath, which may harbor bacteria and make it difficult to withdraw blood from the line. See Central line.

Patients with long term indwelling central catheters can develop sleeve thrombus or an associated fibrin sheath that could theoretically cause physical trapping of FDG [1, 8].

Cardiac Magnetic Resonance for Evaluating Catheter Related FDG Avidity

Skin flora migrates along the dermal tunnel and settles in the fibrin sheath that forms in 3 days around the intravascular portion of the catheter.

Nosocomial bacteraemia in children

Upon valve actuation for treatment, fibrin sheath formation is disrupted, lumens are thrombus free, and high flow rate hemodialysis can be freely delivered.

Phase One Medical Receives US Grant for Catheter Development

The other two reasons of catheter failure are thrombosis and fibrin sheath formation around the catheters.

Two years experience with tunneled dialysis catheters in patients requiring haemodialysis

There is a myriad of causes of catheter dysfunction, including patient positioning, mechanical kinking, malpositioning of the tip out of the right atrium, leakage, drug precipitation, thrombus accumulation, and growth of a fibrin sheath (Chan, 2008).

Similarly, Falk (2008) states that once a peri-catheter thrombus or fibrin sheath occurs, the patient is predisposed to infection; similarly, pericatheter infection increases the risk of thrombosis.

A practical review of the kidney dialysis outcomes quality initiative (KDOQI) guidelines for hemodialysis catheters and their potential impact on patient care

Fibrin sheath thrombus--forms when fibrin adheres to the external surface of the catheter, creating a "sock" over the end of the catheter.

Nurse's guide to understanding and treating thrombotic occlusion of central venous access devices

The distal tip of the LifeJet(TM) F-16 catheter has been specially designed to help resist fibrin sheath formation, a common and costly complication associated with conventional hemodialysis catheters.

HORIZON LAUNCHES LIFEJET F-16 HEMODIALYSIS CATHETER

The common thrombotic complications include fibrin sheath obstruction, subclavian vein thrombosis (SCVT), and superior vena cava thrombosis (SVCT).

* Thrombus accumulation within one or both lumens: the growth of a fibrin sheath over part or all of the exterior of the catheter; or a mural thrombus that changes the flow dynamic in the vessel and therefore the catheter.

Managing catheter dysfunction for better patient outcomes: a team approach

Poorly placed catheters are repositioned, while fibrin sheaths and thrombi are cleared by invasive mechanical methods, such as fibrin sheath stripping, or with thrombolytic therapy.

The use of tissue plasminogen activator infusion to re-establish function of tunneled hemodialysis catheters

Thrombotic occlusions occur as intraluminal clots, fibrin sheaths or tails, or thrombi in the venous walls of the vessels (Herbst, Kaplan, & McKinnon, 1998)(see Figure 1).
