Occlusion of the subclavian vein: a complication of indwelling subclavian venous catheters for hemodialysis.

We are reporting two cases of subclavian vein occlusion following the use of dual lumen subclavian vein catheters as a temporary access to the circulation for hemodialysis. Both patients presented with arm swelling and developed significant collateral circulation established by venography. There was no recanalization of the veins following removal of the subclavian catheters in both cases. This complication has not been previously reported. Its possible pathogenesis is discussed.
