Dialysis Access Mapping Procedure (DAMP)

The Dialysis Access Mapping Procedure (DAMP) is mapping of the upper extremity and is a necessary prerequisite to the creation of any hemodialysis access. It is utilized to evaluate arterial inflow, venous outflow and the adequacy of the venous system to support an autogenous or prosthetic access in the extremity. It will maximize utilization of autogenous fistulae while reducing the need for prosthetic grafts and catheters.
