Double Mesh Nitinol Stent Versus Self-expanding Stent-graft in Recurrent/Resistant Cephalic Vein Arch Stenoses in Dialysis Fistulae: A Comparative Study.

Purpose: To compare the double mesh nitinol stent (DNS) versus the self-expanding stent-graft (SES) in recurrent/resistant cephalic vein arch stenosis in dialysis fistulae.

Materials And Methods: 17 cases with recurrent/resistant stenosis of the cephalic vein arch treated with a DNS were compared retrospectively with 18 cases treated with an SES. Stenting was performed either for significant recoil post-angioplasty with high-pressure balloons or in recurrent stenoses.
