Using arteriovenous fistulae as a dual access for hemodialysis and total parenteral nutrition administration is feasible with a good outcome: a case series.

End stage renal failure patients requiring long term total parenteral nutrition (TPN) often have multiple central line placements due to line infection or occlusion. Sometimes this can cause central venous stenosis or even occlusion. We present three cases in this consecutive series, in which we have successfully used arteriovenous fistulae for both hemodialysis and long term TPN administration as an alternative route without any complications. We therefore think that native AVF and grafts can be used as dual access for hemodialysis and TPN administration provided careful case selection, counselling and follow-up.
