End-stage renal disease (ESRD) arises from many heterogeneous disease pathways that alter the function and structure of the kidney irreversibly, over months or years.End-stage renal disease (ESRD) arises from many heterogeneous disease pathways that alter the function and structure of the kidney irreversibly, over months or years. Haemodialysis (HD) is a lifeline therapy for patients with ESRD. A proportion of hemodialysis patients exhaust all options for permanent vascular access (fistula or graft) in both upper extremities.ePTFE grafts are easily subjected to graft outflow tract intimal hyperplasia, which may lead to graft outlet stenosis and graft thrombosis after a certain period of usage. The commonest cause of PTFE graft failure is intimal hyperplasia (IH) at the venous anastomoses. our study aims to evaluate the influence of double cuffed ePTFE grafts with autologous vein cuffs on the long-term patency of dialysis access, and compare the clinical patency and the complications occurring with the usage of the double cuffed graft to that with standard non cuffed grafts in chronic renal hemodialysis therapy.~this randomized controlled trial will compare the double vein cuffed synthetic arteriovenous graft to the single vein cuffed synthetic and the non cuffed synthetic as regard to long term patency of each modality
