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.

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).

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

too short to reach the back of port body) * Development of fibrin sheath at the tip of the catheter * Catheter or port separation, breakage, or dislodgement * Flushing with small-gauge syringe Agent related * Vesicant potential * Volume infiltrated * Drug concentration * Repeated use of same vein for vesicant administration Patient related * Age (very young or old) * Impaired communication * Compromised circulation * Altered sensory perception * Poor understanding of risk related to anxiety and fear, cultural barriers, and medications Clinician related * Lack of knowledge * Lack of IV skills * Unfamiliarity with central venous catheter use and management * Interruptions and distractions during drug administration

Can you recognize the risk factors for vesicant extravasation?

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.

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.
