Venous stenosis and thrombosis associated with the use of internal jugular vein catheters for hemodialysis.

Previous studies have demonstrated venous stenosis and thrombosis in hemodialysis patients who had repeated or prolonged cannulation of the subclavian vein. Early reports, however suggested that patients with catheters placed in the internal jugular vein were not at risk of such complications. We conducted a retrospective case series to determine if this was correct. We report a series of seven patients who were found to have stenosis of the upper neck veins despite having never had subclavian vein cannulation. We suggest that previous reports suggesting a superior safety profile with internal jugular catheters may have been misleading and propose that all measures be taken to encourage wider use of arteriovenous grafts and fistulae.
