Iatrogenic fistula between prosthetic haemodialysis access graft and autogenous vein: unusual cause of graft thrombosis.

Haemodialysis access graft is so important as to be called a lifeline for the patient on maintenance haemodialysis. The vascular access problem is the leading cause of admission in patients with end-stage renal disease. Many complications of the prosthetic vascular access graft are reported, such as graft thrombosis, infection, aneurysm or pseudoaneurysm, and arterial steal syndrome [1]. We recently experienced two cases of graft thrombosis related to the iatrogenic fistula between haemodialysis access graft and autogenous vein at the needling site during haemodialysis. We report our cases with their clinical manifestation and the treatment outcome and possible methods of prevention [2].
