fibrin sheath

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.

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

There has also been speculation that the presence of a fibrin sheath after removal might be a mechanism for air entry.
2) We report a case of near-fatal pulmonary air embolism after removal of a central venous catheter, with radiologic documentation of a fibrin sheath as the portal for air entry.
5-9) Another complication of central venous catheters is a fibrin sheath or sleeve that commonly forms on indwelling catheters, often within 24 hours of insertion.
The CT angiogram did reveal a fibrin sheath filled with a column of air extending from the subclavian vein into the superior vena cava (Fig.
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.
With a 96% (in-vitro study) and 94% (animal study) reduction in thrombus and fibrin sheath formation,1 the Decathlon Gold catheter has the potential for reducing the frequency of thrombosis-related catheter obstructions (occlusions), which account for 58% of all occlusive events.
The coating on this next generation catheter is firmly bonded to both internal and external catheter surfaces, and has demonstrated the ability to reduce thrombus and fibrin sheath formation in both in vitro and animal studies.
The Fibrex(TM) device incorporates proprietary technology and design elements that, through mechanical means, non-invasively disrupt fibrin sheath formation on both the external and internal surface of vascular access catheters.
The resulting fibrin sheath occludes the side holes of the catheter and ultimately the end holes, rendering the catheter unusable.
