Endovascular Management of Central Venous Stenoses in the Hemodialysis Patient: Results of Percutaneous Therapy

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 arteri-ovenous 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 subcla-vian 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
