Key result
Subclavian vein catheterization for hemodialysis shows ~46% rate of vein stenosis within six weeks.
Why the study?
Subclavian vein catheterization for temporary hemodialysis access can lead to subclavian vein stenosis, but the incidence and natural history were not well characterized.
Does subclavian vein catheterization cause subclavian vein stenosis in patients requiring hemodialysis?
Population
13 patients with subclavian vein catheter for temporary hemodialysis access
Comparison
No comparator; observational assessment of catheterization complication
Design
Observational case series

Subclavian catheterization was associated with early narrowing in this small series; hypothesis-generating and should not yet change practice.

Does subclavian vein catheterization cause subclavian vein stenosis in patients requiring hemodialysis?
Subclavian vein catheterization for hemodialysis frequently leads to subclavian vein stenosis, suggesting lines should be placed contralateral to planned permanent access.
Bruce Spinowitz (1987) conducted an observational in Hemodialysis requiring temporary vascular access (n=13). Subclavian vein catheterization was evaluated on Subclavian vein narrowing (stenosis). Subclavian vein catheterization for hemodialysis resulted in subclavian vein narrowing in 46% (6 of 13) of patients within two to six weeks.
