To determine the safety of power-injectable ports during placement, therapeutic use, and administration of intravenous contrast material using automated mechanical injectors. ⋯ Power-injectable tunneled catheters with attached subcutaneous ports are safe with low rates of complication during placement and dwell time. Power injection of contrast through these ports may be as safe as power injection using other venous access methods.

We report a case of cerebral air embolism after central dialysis line removal and the role of the fibrin sheath as portal (mechanism) of air entry. This case has been documented with computed tomographic (CT) images of the partially air-filled sheath tract.

Randomized Controlled Trial Comparative Study
The effect of peripherally inserted central catheter (PICC) valve technology on catheter occlusion rates--the 'ELeCTRiC' study.
Peripherally Inserted Central Catheters (PICCs) are increasingly being used to provide short to medium-term central venous access. The current study was designed to test the hypothesis that PICC valve technology does not influence PICC occlusion rates. ⋯ Valved PICCs do not appear to influence PICC occlusion rates.
