Polytetrafluoroethylene aorta-vena cava graft for hemodialysis: Report of a case

In children with chronic renal failure, vascular access for hemodialysis is difficult because of the small size of the vessels and the requirement for substantial blood flow through the fistula or graft. As the child grows older, the ease of constructing a satisfactory access usually increases as the vessels increase in size. Unfortunately, this increased ease is often offset by the paucity of suitable access sites because the larger peripheral sites have already been used with only transient success. We report a child with chronic renal failure since 1 month of age with no peripheral sites available because of prior failed procedures who underwent placement of polytetrafluoroethylene limbs to the aorta and vena cava at the age of 6 years. He has continued on hemodialysis for the past 412 years with this technique of vascular access.
