Saphenous vein versus synthetic graft in arteriovenous fistula for hemodialysis in patient with inaccessible veins.

BACKGROUND: An autologous arteriovenous fistula (AVF) provides an optimal and secure way for managing the condition. An optimal blood supply to hemodialysis is linked to decreased incidence of complications and mortality, as well as reduced expenses. The objective of this research was to evaluate the outcome of people with suboptimal superficial venous system quality or who had exhausted all available arteriovenous fistula options, who received either autologous saphenous vein graft or polytetrafluoroethylene (PTFE) interposition graft as an access for effective hemodialysis.

METHODS: This prospective randomized controlled trail was carried out on fifty cases with chronic renal failure on hemodialysis and inaccessible superficial veins of both upper limbs for AVF. Cases were separated into two equal groups: Group A: cases performed saphenous vein reposition graft for hemodialysis access. Group B: cases who underwent PTFE interposition graft for prosthetic hemodialysis access.

RESULTS: Time for maturation and time for graft maturation, operative time, hospital stay, and postoperative HB were significant increase in group A in contrast to group B (P<0.05). Blood loss was significant decrease in group A in contrast to group B (P<0.001).

CONCLUSIONS: Patients underwent saphenous vein repositioning graft for hemodialysis access required prolonged operative time and hospital stay. Cases that underwent PTFE interposition graft for prosthetic hemodialysis access were less in time for maturation and time for graft maturation.
