Clinical TrialThrombus on indwelling central venous catheters: the histopathology of "Fibrin sheaths".
Central venous catheters (CVC) may fail for many reasons, though "fibrin sheaths" blocking catheter ports are usually implicated. We examined the sheaths removed from dialysis catheters to determine their histopathology. ⋯ Dialysis catheters fail because of thrombus formation. This can occur in either the absence or presence of a protein coating on the catheter, the so-called "fibrin sheath."

Peripheral venous access ports: outcomes analysis in 109 patients.
To perform a retrospective outcomes analysis of central venous catheters with peripheral venous access ports, with comparison to published data. ⋯ Peripheral ports for long-term central venous access placed by interventional radiologists in the interventional radiology suite are as safe and as effective as chest ports.
