Abstract The purpose of this study was to determine the functional results of transvenous angioplasty for the treatment of central venous stenoses in patients with failing upper extremity arteriovenous access. Two hundred consecutive patients presented with threatened arteriovenous access from January 1999 through July 2002. Angiographic evidence of central venous stenosis was present in 35 patients (18\%) (superior vena cava 5, brachiocephalic veins 14, and subclavian veins 18). Follow-up averaged 873 days from the date of initial intervention. The initial technical success rate was 89\%. Primary patency for each intervention was 85\% at 30 days, 55\% at 6 months, 43\% at 1 year, and 0\% at 2 years. Assisted primary patency rates were 88\% at 30 days, 80\% at 1 year, and 64\% at 2 years. Freedom from central venous dialysis catheter placement was 82\% at 30 days, 63\% at 3 months, 51\% at 1 year, 37\% at 2 years, and 25\% at 3 years. Freedom from a dialysis catheter was superior in those patients with autogenous arteriovenous fistulas. Transvenous angioplasty appears to be beneficial for hemodialysis patients with central venous stenoses, and it helps preserve functional access in the affected extremity, particularly in patients with autogenous fistulas.
