Retrospective assessment of risk factors to predict tunneled hemodialysis catheter outcome.
To identify factors that may influence the function, outcome, and complications associated with tunneled hemodialysis catheters. ⋯ Hypertension is a risk factor for poor outcome of tunneled hemodialysis catheters as measured by total complication rate requiring catheter removal or exchange. In this retrospective study, no other specific risk factors predicted an increased need for removal or exchange of tunneled hemodialysis catheters.

Case ReportsDelayed migration of a catheter fragment from the left to the right pulmonary artery.
A 45-year-old woman is described in whom an intrapulmonary venous access catheter fragment, originally left in place when discovered 1 year after port removal, migrated from one side to the other 2 years later. The patient underwent uncomplicated percutaneous removal of the fragment via the right internal jugular vein. The observed fragment mobility adds further argument for removing all intravenous catheter fragments, even if they have embolized to the pulmonary artery.
