Self-expanding stents for the treatment of a long venous stenosis in a dialysis shunt: case report.

This report describes the successful management of a long venous stenosis that resulted from intimal hyperplasia in a synthetic hemodialysis graft. The recurrent stenosis was kept patent with four overlapping, self-expanding metallic stents, which allowed coverage of the 16 cm distance from the axillary vein to the synthetic graft.
