“…The published reports cite complication rates of 4-6% [1,3,5,6] occur ring with the initial insertion of the catheter. This rate is not much different from cannulation of the subclavian vein done for nondialytic purposes [2,4,10,11], Late complications from these cannulae that have been re ported include partial thrombosis of the subclavian vein, air emboli, infection, catheter thrombosis and catheterinduced hemopericardium [7], To this list must be added contralateral hemothorax. The introduction of nonrigid urethane and silastic catheters may minimize the risk of perforation.…”
