Superior vena cava syndrome due to subclavian hemodialysis catheters.

The widespread use of subclavian dialysis catheters has revealed a high incidence of venous thrombosis and exposed their potential to cause major obstructive complications that may compromise permanent vascular access. We describe for the first time a patient who developed superior vena cava syndrome secondary to central vein stenosis caused by multiple uses of subclavian dialysis catheters. Central vein stenosis in our patient probably caused the failure of permanent vascular accesses in the upper extremities and rendered both arms useless for any further temporary or permanent vascular access. In view of these late vascular complications, use of subclavian dialysis catheters should be kept to a minimum by creating an early permanent vascular access.
