Subclavian vein stenosis as a complication of subclavian catheterization for hemodialysis.

Thirteen patients had placement of a subclavian vein catheter for temporary vascular access for hemodialysis. Peripheral venography was performed within two to six weeks of catheter placement. Forty-six percent (six of 13 patients) developed subclavian vein narrowing, which resolved in two patients. The duration of catheter placement had no impact on the incidence of this complication. Subclavian vein catheterization can frequently lead to subclavian vein stenosis, which often will resolve spontaneously. Consideration should be given to placement of subclavian lines on the contralateral side of a planned permanent vascular access.
