Comparative StudyMalfunctioning and infected tunneled infusion catheters: over-the-wire catheter exchange versus catheter removal and replacement.
To compare the safety and effectiveness of over-the-wire catheter exchange (catheter-exchange) with catheter removal and replacement (removal-replacement) at a new site for infected or malfunctioning tunneled infusion catheters. ⋯ Catheter-exchange of tunneled infusion catheters results in a higher infection rate compared with removal-replacement at a new site. The rate of catheter malfunction is not significantly different between the two groups. Catheter-exchange is an alternative for patients with tunneled infusion catheters who have limited venous access, but this technique should not be expanded for use in all patients. Because of the size of this initial study, further investigation is needed to verify the results in a larger sample size.

Comparative StudySilicone and polyurethane tunneled infusion catheters: a comparison of durability and breakage rates.
To examine the overall durability and breakage rates of dual-lumen silicone catheters in comparison with power-injectable dual-lumen polyurethane catheters. ⋯ There were fewer catheter fractures with the polyurethane catheter compared with the silicone catheter, although there was no difference in the total access site service interval for the two catheter types.

Case ReportsTherapeutic sclerosis of a small liver cyst that caused obstructive jaundice.
The authors describe the case of a small liver cyst (2 cm in diameter) causing obstructive jaundice that was treated with aspiration and therapeutic sclerosis. The procedure was performed with use of a microcatheter and wire system to access the cyst, which was injected with minocycline hydrochloride. At present, 9 months after treatment, the levels of hepatobiliary enzymes are within normal ranges, and no sign of cyst regrowth has been detected on imaging.
