A salvage technic for extruded arteriovenous shunts.
In view of the often prolonged periods of pretransplantation and chronic dialysis, every effort should be made to maintain existing arteriovenous shunts or fistulas and to salvage eroded ones when possible. The transposition of unwounded bipedicle flaps or small regional rotation advancement flaps over exposed cannulas is a surgical technic that can salvage eroded shunts and prevent their extrusion and removal.
